Ultra Filtration Plant for Clean, Safe & Reliable Water
Surface water is full of bacteria. River intake with high turbidity. Wastewater that needs polishing before reuse. These are not problems a basic sand filter can solve. They need an Ultra Filtration Plant — a membrane system that physically blocks bacteria, viruses, suspended solids, and colloidal matter without a single chemical. At Unitech Water Solution, we manufacture UF plants that deliver consistent, safe, chemical-free output across industries, municipalities, and water businesses. As a trusted Ultra Filtration Plant manufacturer India with 20+ years of experience and 5,874+ successful projects, we build systems designed for performance — not just paperwork.
Request A QuoteWhat Is an Ultra Filtration Plant?
An Ultra Filtration Plant — or UF plant — is a low-pressure membrane filtration system using hollow-fibre membranes with pore sizes between 0.01 and 0.1 microns. These pores are small enough to physically block bacteria, viruses, suspended solids, colloidal particles, endotoxins, and high-molecular-weight organics. No chemistry is involved — the membrane does the work.
Feed water enters the UF membrane plant under low pressure. Clean permeate flows through the membrane while contaminants are retained on the feed side and periodically flushed away during automated backwash cycles. The result is consistently clean, low-turbidity output — regardless of how variable the incoming water quality is.
One of the most powerful uses of a UF plant is as a UF plant as pre-treatment for the RO system. UF reduces the SDI (Silt Density Index) of the feed water to below 3 — the safe threshold for RO membrane feed. This protects your RO membranes, extends their lifespan, and improves overall system recovery. If you are operating an Industrial RO Plant, adding UF upstream is one of the most valuable improvements you can make.
Who Benefits from an Ultra Filtration Plant?
A UF plant from Unitech Water Solution serves a wide range of real-world water challenges:
- Municipal Drinking Water Supply: Towns and villages treating river or lake water need an UF plant for drinking water that removes pathogens reliably — without chemical handling risks. Our Sewage Treatment Plant works hand-in-hand with UF for complete municipal water management.
- Pharmaceutical & Hospital Facilities: Endotoxin-free, bacteria-free water is non-negotiable. A UF water plant for the pharma and food industry is the recommended first stage before RO or further high-purity processing. For dialysis-grade water, combine UF with our Dialysis RO Plant.
- Food & Beverage Manufacturing: Breweries, dairies, juice plants, and carbonated drinks manufacturers need an ultrafiltration plant for industrial water that delivers low-turbidity, bacteria-free process water consistently — every shift, every season.
- Mineral Water & Packaged Drinking Water Plants: A UF plant for drinking water as the first treatment stage ensures ISI and FSSAI compliance by delivering bacteria-free, SDI-safe feed to your RO system. Pair it with our SS RO Plant for a complete hygienic production line.
- Textile, Dyeing & Chemical Industries: High-turbidity process water with dye particles and colloidal matter is handled effectively by an ultrafiltration water treatment plant. It enables water reuse within the plant, cutting freshwater consumption and reducing effluent discharge.
- Power Plants & Steel / Cement Industries: Cooling tower makeup and boiler pre-feed water need a reliable Ultra Filtration Plant to remove suspended matter at scale. Combine with our Water Softening Plant for complete pre-treatment.
- Wastewater Tertiary Treatment & Water Reuse: After biological treatment, a UF plant polishes the effluent for safe reuse within the facility — reducing freshwater dependency and helping meet environmental discharge norms.
Why Unitech Water Solution Stands Apart
We Design for Your Water — Not a Generic Template
Most Ultra Filtration Plant suppliers provide a standard system and expect your water quality to fit it. At Unitech Water Solution, every UF membrane plant begins with your actual water report — turbidity, SDI, bacterial load, flow rate, and end-use application. We then engineer the membrane array, backwash frequency, and pre-treatment specifically for those conditions. You get a system built for your water, not whatever was easiest to quote.
Two Decades of Field Experience Behind Every Build
Since 2004, Unitech Water Solution has delivered water treatment projects across pharmaceuticals, food processing, municipalities, and heavy industry. Our engineers have worked with every type of surface water, every type of industrial effluent, and every type of site constraint. Being an experienced Ultra Filtration Plant manufacturer India means we bring real field knowledge — not just factory specs — to your project.
No Chemicals. Lower Running Cost. Simpler Operations.
Chemical-free operation is not just a selling point — it is a meaningful daily advantage. Your UF plant from Unitech Water Solution needs no coagulants, flocculants, or disinfectants in the UF stage. That means no chemical procurement, no dosing system calibration, no chemical handling hazards for your staff, and no disposal compliance headaches. An ultrafiltration plant for industrial water running without chemicals is genuinely simpler to manage month after month.
Genuine DOW Filmtec UF Membranes — Certified, Traceable, Long-Lasting
The performance of any UF water plant for the pharma and food industry comes down to membrane quality. Unitech Water Solution is an authorised DOW Filmtec channel partner in India. Every system we supply uses genuine, certified DOW membranes with documented rejection rates and full supply traceability. This is a meaningful difference when your water output has to meet regulatory standards.
Factory-Tested. Site-Ready. No Surprises.
Every Ultra Filtration Plant manufacturer Ahmedabad built from our Vatva GIDC factory is fully assembled, tested on water, and commissioned before dispatch. Backwash sequences, pressure alarms, flow rates — all verified. When our team arrives at your site, they are commissioning a system that has already worked. That makes your go-live fast, clean, and reliable.

FAQs
An Ultra Filtration Plant uses 0.01–0.1 micron membranes to remove bacteria, viruses, and suspended solids without removing dissolved salts. RO removes dissolved salts but needs clean feed water. A UF plant as pre-treatment for the RO system combines both technologies for complete purification.
No. A UF plant removes contaminants through physical membrane filtration — no coagulants, flocculants, or disinfectants are needed in the UF stage. This makes an ultrafiltration water treatment plant simpler, safer, and more economical to run every day.
An Ultra Filtration Plant removes bacteria (99.99% rejection), viruses, suspended solids, colloidal particles, endotoxins, silt, silica, and high-molecular-weight organics. It does not remove dissolved salts — combine with RO for full demineralisation.
Yes. A UF water plant for the pharma and food industry delivers bacteria-free, endotoxin-free, low-turbidity water meeting WHO, GMP, and BIS standards. It is the recommended pre-treatment before RO in pharmaceutical, hospital, and food production applications.
Yes. An ultrafiltration plant for industrial water treatment is designed to handle river water, surface water, and secondary treated effluent with variable turbidity. The automated backwash system maintains consistent flux even as feed water quality changes.
