I need a water purification system for industrial wastewater treatment.

Designing or selecting an industrial wastewater purification system requires matching the treatment technology to your specific chemical or biological contaminant profile, flow rate, and discharge or reuse goals.

Core Industrial Wastewater Technologies

1. Reverse Osmosis (RO) & Nanofiltration (NF): Excellent for removing dissolved salts, heavy metals, and residual organics, often used as a tertiary polishing step for water reuse.[1]
2. Membrane Bioreactors (MBR): Combines biological secondary treatment with membrane filtration for high-efficiency breakdown of organic matter and suspended solids.
3. Dissolved Air Flotation (DAF): A physical-chemical pretreatment process used to separate suspended solids, oils, fats, and greases from the wastewater stream.
4. Electrocoagulation (EC): Uses electrical current to destabilize suspended, emulsified, or dissolved contaminants, effectively removing heavy metals and dyes.
5. Advanced Oxidation Processes (AOP): Utilizes ozone, hydrogen peroxide, and/or UV light to break down stubborn or toxic refractory organic compounds that biological systems cannot handle.

Next Steps for Customization

To configure or source a proper skid-mounted or integrated system (such as those customizable via platforms like Made-in-China.com Wastewater Equipment ), it helps to narrow down the operational parameters.[1][2]

If you'd like to narrow this down, please share:

• What industry or specific contaminants (e.g., heavy metals, oils, high BOD/COD, salts) are in the wastewater?
• What is your estimated daily flow rate (in gallons per day or cubic meters per hour)?
• Is the goal discharged compliance to a municipal sewer/environment or internal water recycling/reuse?

Yes. For industrial wastewater, the right system is usually a treatment train, not simply a standalone RO or filter. The configuration depends heavily on what is in the wastewater and what quality you need at the outlet.

A typical industrial system might look like:

Equalization → pH adjustment → coagulation/flocculation → DAF/clarifier → biological treatment or MBR → UF → RO → disinfection/polishing

EPA's industrial wastewater database documents technologies including DAF, biological treatment, MBR, UF/MF, activated carbon, ion exchange, nanofiltration, and RO, with treatment performance data from pilot- and full-scale systems.

Which technology you need depends on the wastewater

• Oil & grease: oil/water separator and/or DAF
• Suspended solids: clarification, DAF, multimedia filtration, UF
• High BOD/COD: biological treatment such as activated sludge, MBBR, or MBR
• Heavy metals: chemical precipitation, coagulation, electrocoagulation, or ion exchange
• Dissolved salts/TDS: RO or sometimes nanofiltration
• Organic chemicals: activated carbon, biological treatment, oxidation/AOP, or combinations
• Nitrogen/phosphorus: biological nutrient removal or specialized chemical treatment
• Very high-quality reuse water: typically UF/MBR followed by RO, with appropriate pretreatment

RO is particularly useful for dissolved salts and many dissolved contaminants, but it creates a concentrate/reject stream, so that disposal or further treatment has to be designed into the system.

I can size a system for you

Send me these six things:

1. Industry: e.g. metal finishing, food processing, pharmaceutical, manufacturing, oil & gas
2. Wastewater flow: gallons/day (GPD) or gallons/minute (GPM)
3. Wastewater analysis: pH, TSS, BOD, COD, TDS/conductivity, oil & grease, metals, nitrogen, etc.
4. Required treated-water quality: discharge, sewer discharge, or reuse/recycle
5. Operating hours: hours/day and days/week
6. Budget: approximate capital budget, if known

If you don't have a laboratory analysis yet, tell me the industry and approximate flow and I can give you a preliminary treatment train and equipment sizing.

For example, if you're treating 10,000 GPD of manufacturing wastewater for reuse, I can work out a preliminary process flow, tank/filter/membrane sizes, expected recovery, reject volume, and a rough equipment budget.

Selecting an industrial wastewater treatment and purification system depends heavily on your specific effluent composition, flow rate, and discharge or reuse goals. Industrial setups typically utilize a multi-stage treatment train rather than a single device.

Common Industrial Purification Technologies

• Reverse Osmosis (RO) Systems: High-pressure membrane filtration used to remove dissolved ions, salts, and organics (such as the [Zonesun Industrial RO Systems Go to product viewer dialog for this item. ](https://www.zonesunpack.com/el/products/zonesun-zs-ro10t-industrial-10t-reverse-osmosis-system-water-purification-plant-for-beverage-pharma?srsltid=AfmBOooeayIiEEej_6DQmzc9TECgmD0HeLcbt6bS5VPb5PaWj7_QWv-eeoo) or commercial setups on US Water Systems ). Ideal for polishing and water reuse.
• Modular/Clarification Units: Physical-chemical treatment systems (like modular stainless steel units found via Electro Plating Tank System ) designed for heavy metals, suspended solids, and pH adjustment.
• Advanced Oxidation & Filtration: Integration of activated carbon, UV, ozone, and ion exchange (custom-engineered by providers like Veolia Water Technologies ) to tackle heavy chemical oxygen demand (COD) or specific pharmaceutical/chemical contaminants.

To help narrow down the right configuration or vendor specifications, please share:

• The industry type (e.g., plating, food & beverage, chemical, pharma)
• Estimated daily flow rate (in gallons per day or cubic meters per hour)
• Key contaminants or parameters (e.g., high TDS, heavy metals, oils/grease, high BOD/COD)
• Your primary objective (meeting municipal discharge limits vs. zero liquid discharge/water recycling)

Yes. For industrial wastewater, I’d recommend designing a treatment train, rather than buying a single “water purification system.” The right configuration depends heavily on the wastewater chemistry, flow rate, and required effluent quality. EPA’s industrial wastewater database specifically evaluates treatment systems by industry, pollutant, and treatment technology.

A typical industrial system

A common configuration is:

Equalization → pH adjustment → solids/oil removal → biological treatment → UF/MBR → RO → disinfection/reuse

Depending on your wastewater, components can include:

• Equalization tank — smooths out flow and contaminant fluctuations.
• DAF/clarifier — removes suspended solids, oils, and grease.
• Biological treatment (MBBR/activated sludge/MBR) — reduces biodegradable COD/BOD and can address nitrogen. EPA identifies MBBR and MBR as established industrial biological-treatment approaches.
• UF/MF — removes fine suspended solids and colloidal material.
• Reverse osmosis (RO) — removes dissolved salts and many small dissolved contaminants; EPA classifies RO as a membrane technology for removing small ions.
• Activated carbon/AOP — useful for specific dissolved organics or difficult-to-degrade contaminants.
• Disinfection — UV, ozone, or chemical treatment where required.
• Concentrate management — essential if RO is used; the rejected stream needs a disposal or further-treatment strategy.

If your objective is high-quality water reuse, an MBR followed by RO can be particularly attractive. MBR combines biological treatment with membrane filtration and can produce low-solids effluent suitable for further polishing.

I can size a system for you

Send me these 6 numbers/details:

1. Industry/process: e.g. food processing, metal finishing, oil & gas, pharmaceutical, textile, etc.
2. Wastewater flow: gallons/day (or gallons/hour)
3. Current water analysis: pH, TDS/conductivity, COD, BOD, TSS, oil & grease, ammonia/nitrogen, metals, and any other known contaminants.
4. Required treated-water quality: discharge, sewer discharge, process reuse, boiler feed, cooling tower, or near-zero-liquid-discharge.
5. Operating schedule: hours/day and days/week.
6. Location: state/country, because discharge requirements are site-specific. In the U.S., NPDES requirements and effluent guidelines depend on the industrial category and discharge situation.

For example, if you tell me “food-processing wastewater, 100,000 gal/day, COD 2,000 mg/L, BOD 1,000 mg/L, TSS 500 mg/L, pH 6–9, and we want to reuse the water,” I can lay out a preliminary treatment train, estimated equipment capacities, footprint, major equipment list, and a rough CAPEX/OPEX range.

Selecting an industrial wastewater purification system requires matching the treatment technology to your specific chemical or biological contaminants, flow rates, and discharge or reuse goals.

Common industrial purification technologies and configurations include:

• Membrane Bioreactors (MBR) — Combines biological treatment with membrane filtration to remove suspended solids and organic matter effectively. Ideal for high-strength organic wastewaters.[1]
• Commercial Reverse Osmosis (RO) — Heavy-duty systems (such as high-capacity units available at Clean Water Store or US Water Systems ) use high-pressure pumps and thin-film composite membranes to strip dissolved solids, salts, and heavy metals for water reuse.[1][2]
• Modular Stainless Steel Systems — Corrosion-resistant 304 or 316-grade setups (like modular units found on platforms like Electro Plating Tank System ) are tailored for metal finishing, plating, and heavy industrial effluent.[1]
• UV Disinfection Systems — Advanced ultraviolet units (such as the [Hallett UV Pure Go to product viewer dialog for this item. ](https://uswatersystems.com/products/1-hallett-uv-pure-uv-for-wastewater-flows-up-to-18-gpm-model-750w?variant=45584046391600&country=US&currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&srsltid=AfmBOoqbR8rzzjoHl6GLi52X_psZ34o7B2_P-mcOJYlceNSI1oJCxwD-4mo) ) provide chemical-free pathogen and microorganism destruction for final effluent cleanup.[1]

To help narrow down the exact specifications or configure a setup, please share:

• Your industry type (e.g., food processing, metal plating, chemical manufacturing)
• The estimated daily flow rate (in gallons or cubic meters per day)
• Your primary target contaminants or discharge requirements (e.g., TDS, BOD, heavy metals)

Yes. For industrial wastewater, I would not recommend buying a standalone RO/filter system without first defining the wastewater chemistry. Industrial systems are usually a treatment train, and the right train depends heavily on the contaminants and discharge/reuse target.

A typical industrial treatment train

A common configuration is:

Screening → Equalization → pH adjustment → Oil/grease removal or DAF → Biological treatment → Clarification/UF → RO → Disinfection/reuse

EPA's industrial wastewater database lists technologies including DAF, biological treatment, MBR/MBBR, activated carbon, ion exchange, ultrafiltration, nanofiltration, and RO, among others.

• DAF: good for suspended solids, oil and grease.
• Biological treatment / MBBR / MBR: useful when BOD/COD and nutrients are significant.
• UF/MF: removes suspended solids and provides membrane pretreatment.
• Activated carbon: useful for certain dissolved organics and residual contaminants.
• RO: appropriate when you need substantial dissolved-solids/salt removal or high-quality process/reuse water.
• Evaporation/ZLD: worth considering when discharge is severely restricted and you need to minimize or eliminate liquid waste.

Important: RO generally should not be placed directly on untreated industrial wastewater. Pretreatment is critical because solids, biological growth, colloids and scaling can foul RO membranes and increase operating costs.

If you want a system I can size

Send me these 7 things:

1. Industry/process: e.g. metal finishing, food, textile, chemical, automotive, pharmaceutical
2. Wastewater flow: gallons/day or gallons/hour
3. Current water analysis: pH, TSS, TDS/conductivity, BOD, COD, oil & grease, metals, nitrogen/phosphorus, etc.
4. Main contaminants you need removed
5. Required output: sewer discharge, surface-water discharge, or water reuse
6. Desired recovery: e.g. 50%, 75%, 90%+
7. Budget: approximate equipment budget

If you give me flow rate + industry + a wastewater lab analysis, I can recommend a specific treatment train, approximate equipment capacity, and identify commercially available industrial systems. EPA's IWTT is also useful for matching particular industrial pollutants with proven treatment technologies.

If your goal is specifically RO/reuse, I can also narrow this down to a complete pretreatment + UF + industrial RO system rather than a drinking-water RO unit.

Selecting an industrial wastewater treatment and purification system depends heavily on your specific contaminants, flow rate, and discharge or reuse goals. Industrial systems are rarely "one-size-fits-all" and generally combine multiple physical, chemical, and biological stages.

Core Industrial Treatment Technologies

• Reverse Osmosis (RO) & Nanofiltration: Highly effective for removing dissolved solids, ions, and heavy metals. Heavy-duty units like the [ZONESUN ZS-RO10T Industrial RO System Go to product viewer dialog for this item. ](https://www.zonesunpack.com/ru/products/zonesun-zs-ro10t-industrial-10t-reverse-osmosis-system-water-purification-plant-for-beverage-pharma?srsltid=AfmBOop3ofEwwF5OPurNUZQ_2GfYwxV4nfCNuTTygJyrhSlcuA9HHmXC1rE) or high-capacity setups via [US Water Systems Defender Commercial RO Go to product viewer dialog for this item. ](https://uswatersystems.com/products/us-water-systems-defender-commercial-floor-mount-reverse-osmosis-system-2000-to-16000-gpd?variant=49945661407536&country=US&currency=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&srsltid=AfmBOopOHr6_m5O_lFvRxb_iTKUP46gfxX6TXUpHF1_BYrcZjID92qRGwRE) achieve high desalination and purity rates.[1][2]
• Modular Chemical & Physical Systems: Ideal for metal finishing, plating, and heavy manufacturing. Modular configurations like the [Stainless Steel Wastewater Treatment System (5000L)Go to product viewer dialog for this item. ](https://electroplatingtanksystem.com/products/stainless-steel-wastewater-treatment-system-modular-design-5000l) provide scalable capacity and corrosion resistance.[1]
• Ultrafiltration (UF) & Media Filtration: Used as a pretreatment step to remove suspended solids, turbidity, oils, and large macromolecules before secondary membrane treatment.
• Biological & Advanced Oxidation (AOP): Used for breaking down high chemical oxygen demand (COD), biological waste, or persistent organic compounds.

To help narrow down the right configuration and ballpark pricing, could you share:

• What is your industry type (e.g., food & beverage, metal plating, chemical processing)?
• What is your estimated daily flow rate (Gallons Per Day or cubic meters/day)?
• What are the key target contaminants or regulatory limits you need to meet?

For industrial wastewater treatment, the right purification system depends on what contaminants are in the wastewater, the flow rate, and whether you need discharge compliance or water reuse. Industrial systems are usually engineered as a treatment train rather than a single filter.

A typical industrial wastewater purification system may include:

1. Pretreatment

Used to protect downstream equipment.

• Screening — removes large solids and debris
• Oil/water separation — removes free oils and hydrocarbons
• Equalization tank — balances fluctuating wastewater flow and contaminant loads
• pH adjustment — neutralizes acidic or alkaline wastewater

Waters Geo## 2. Primary treatment

For suspended solids and chemical contaminants:

• Coagulation/flocculation + clarification
• Dissolved air flotation (DAF) for oils, fats, and suspended solids
• Chemical precipitation for heavy metals (such as chromium, nickel, copper, zinc)

3. Biological treatment (for organic wastewater)

Best for industries with high BOD/COD:

• Activated sludge systems
• Moving Bed Biofilm Reactor (MBBR)
• Membrane Bioreactor (MBR)

MBR combines biological treatment with membrane filtration and can provide high-quality effluent suitable for many reuse applications.

4. Advanced purification

Used when high-quality reuse water is required:

• Ultrafiltration (UF) — removes fine suspended solids, bacteria, and colloids
• Nanofiltration (NF) — removes some dissolved ions and organic compounds
• Reverse osmosis (RO) — removes dissolved salts and many dissolved contaminants

Waters Geo DuPontA common high-recovery reuse configuration is:

Wastewater → Screening → Equalization → DAF/Chemical Treatment → MBR → RO → Reuse Water

RO is often used as a polishing step after pretreatment or biological treatment to achieve low dissolved solids water quality.

Common system choices by industry

To recommend a properly sized system, I would need:

1. Industry type (food, metal, chemical, textile, etc.)
2. Wastewater flow rate (gallons/day or m³/day)
3. Main contaminants (COD, BOD, TSS, oil, metals, salts, pH, etc.)
4. Goal: - discharge to sewer

• meet environmental discharge limits
• recycle/reuse water
• zero liquid discharge (ZLD)

If you provide those details, I can suggest a treatment configuration and approximate equipment sizing.

Common system choices by industry

To recommend a properly sized system, I would need:

An industrial wastewater purification system needs to be designed around the contaminants, wastewater flow rate, discharge/reuse requirements, and industry type. There is no single “best” system; most facilities use a treatment train combining physical, chemical, biological, and/or membrane processes. The U.S. EPA’s Industrial Wastewater Treatment Technology Database lists many proven technologies, including filtration, dissolved air flotation, biological treatment, activated carbon, ion exchange, reverse osmosis, and advanced oxidation processes.

Common industrial wastewater treatment system configuration

1. Pre-treatment

• Bar screens or strainers (remove large solids)
• Oil/water separators (remove oils and grease)
• Equalization tank (balances flow and pollutant loading)

2. Primary treatment

• Coagulation/flocculation
• Clarification or dissolved air flotation (DAF)
• Chemical precipitation for metals or suspended solids

3. Secondary treatment

• Activated sludge systems
• Moving bed biofilm reactors (MBBR)
• Membrane bioreactors (MBR)
• Anaerobic treatment for high-organic wastewater

4. Advanced purification (as needed)

• Reverse osmosis (RO) for dissolved salts and high-purity reuse water
• Ultrafiltration/nanofiltration for fine solids and larger dissolved contaminants
• Activated carbon for organic chemicals, color, and odors
• Ion exchange for specific ions (such as metals or hardness)
• Advanced oxidation (ozone, UV, peroxide processes) for difficult-to-remove organics

Waters Geo## Example systems by wastewater type

• Food & beverage wastewater

• Screening → DAF → biological treatment → filtration → disinfection

• Metal finishing / plating wastewater

• Equalization → pH adjustment → chemical precipitation → filtration → ion exchange/RO

• Chemical or pharmaceutical wastewater

• Equalization → biological treatment (if biodegradable) → activated carbon → advanced oxidation or membranes

• Textile wastewater

• Coagulation → DAF → biological treatment → color removal (carbon/AOP) → filtration

• High-salinity wastewater

• Pretreatment → RO → evaporator/crystallizer (for near-zero liquid discharge systems)

To size the right system, I would need:

1. Industry type (e.g., manufacturing, food, chemical, mining, metal finishing)
2. Wastewater flow: - gallons per day (GPD), gallons per minute (GPM), or m³/day
3. Wastewater analysis (if available): - pH

• COD/BOD
• TSS
• Oil & grease
• Metals
• Salinity/TDS
• Specific chemicals

4. Goal: - Discharge to sewer?

• Surface water discharge?
• Reuse/recycle water?
• Zero liquid discharge?

5. Location and regulatory requirements

If you provide those details, I can help outline a suitable treatment train and approximate equipment list.

An industrial wastewater treatment system cannot be purchased as a "one-size-fits-all" product because the ideal configuration depends entirely on your specific industry, the contaminants present, and your daily water volume. To achieve compliance or clean water for reuse, industrial facilities typically deploy a multi-stage treatment train combining physical, chemical, and biological technologies.

⚙️ Core Technologies by Treatment Stage

A typical industrial system sequences these specialized technologies:

[Influent Feed] ➡️ Primary (Physical) ➡️ Secondary (Biological/Chemical) ➡️ Tertiary (Advanced Purity) ➡️ [Clean Effluent]

1. Primary Treatment (Physical Separation)

• Dissolved Air Flotation (DAF): Uses micro-air bubbles to float fats, oils, grease (FOG), and suspended solids to the surface for skimming. Ideal for food processing and oil/gas.
• Automatic Self-Cleaning Strainers & Bag Filters: Trap large debris, sand, and heavy sediment to protect downstream equipment from clogging.

2. Secondary Treatment (Biological & Chemical Breakdown)

• Membrane Bioreactors (MBR): Combines suspended growth biological treatment with ultrafiltration membranes. Highly effective for removing high biochemical oxygen demand (BOD) and organics in pharmaceutical or food industries.
• pH Neutralization & Chemical Precipitation: Automatically injects acids or bases to balance pH and introduces flocculants to clump dissolved heavy metals into solids for easy removal.

3. Tertiary & Advanced Treatment (Polishing & Purification)

• Ultrafiltration (UF) Systems: Pressure-driven membrane systems that strip out sub-micron particles, emulsified oils, and pathogens.
• Industrial Reverse Osmosis (RO): Forces water through semi-permeable membranes under high pressure to reject up to 99% of total dissolved solids (TDS), heavy metals, and chemical ions. Turnkey skid-mounted units like the [US Water Systems Patriot XL Series Go to product viewer dialog for this item. ](https://uswatersystems.com/products/us-water-systems-patriot-xl-turnkey-skid-mounted-commercial-industrial-reverse-osmosis-system-2000-to-16000-gpd) are widely deployed for process water purification. [1][2][3][4]
• Vacuum Evaporation & Distillation: Clean separation tech that boils off clean water while concentrating complex chemical waste, maximizing wastewater recovery.
