Industrial ultrafiltration uses hollow-fibre or spiral membranes with pores around 0.01-0.1 micron to remove suspended solids, colloids, bacteria and most viruses — without removing dissolved salts and without chemicals.
Its two main industrial roles are worth distinguishing. As a standalone treatment, UF produces clear, microbiologically safe water where TDS is already acceptable — surface water clarification, for instance. As RO pre-treatment, UF delivers consistently low-turbidity feed regardless of raw water variation, which extends membrane life significantly and is why it increasingly replaces conventional multigrade sand filtration on plants with variable surface-water feed.
The economics favour UF pre-treatment where raw water quality swings — monsoon turbidity, canal supply, river intake. Where feed is stable borewell water, conventional filtration is usually adequate and cheaper.
UF vs conventional filtration vs RO
- Multigrade sand filtration — cheapest, effective on stable feed, but output turbidity follows input turbidity.
- Ultrafiltration — consistent sub-0.1 NTU output regardless of feed variation, removes bacteria and most viruses, no chemicals, but higher capex and needs backwash.
- Reverse osmosis — the only one that removes dissolved salts. UF and sand filtration do not reduce TDS at all.
- Common architecture: UF as pre-treatment feeding RO, which protects the RO membranes and stabilises plant performance through monsoon.
Multi-stage purification architecture
Commercial and industrial systems are engineered as a treatment train, not a single appliance. Each module protects the one after it, and skipping a stage to save capex is the most common reason plants fail early.
- Pre-treatment module — multigrade sand filter removes suspended solids and turbidity; activated carbon filter strips chlorine and organics that would oxidise the RO membrane.
- Softening or antiscalant dosing — protects membranes from calcium and magnesium scaling. On hard feed water this is not optional.
- High-pressure RO module — heavy-duty booster pump drives feed water through industrial spiral-wound membranes at 12-18 bar.
- Post-treatment disinfection — UV disinfection and/or ozonation, with mineral dosing where potable taste matters.
- Microprocessor / PLC control — auto start-stop on tank level, dry-run protection, low and high pressure cut-offs, and timed membrane flushing to extend membrane life.
Tip
Total cost of ownership, not just capex
Capital cost is usually 30-40% of what a commercial water system costs you over five years. The rest is power, membrane and cartridge replacement, reject water, and labour. Two plants with identical price tags can differ by 60% in five-year TCO.
- Power — energy-efficient pumps and correctly sized motors are the largest controllable operating cost on plants above 500 LPH.
- Recovery ratio — a plant recovering 70% instead of 45% cuts both your feed water bill and your reject disposal volume substantially.
- Membrane life — driven almost entirely by pre-treatment quality and flushing discipline, not by membrane brand.
- Consumables — cartridge filters, antiscalant and salt for softener regeneration, budgeted monthly rather than as surprises.
- AMC and downtime — for a production facility, unplanned downtime usually dwarfs every other line item.
What a quotation includes
- Raw water characterisation including turbidity variation across seasons
- UF membrane module selection and skid design
- Backwash and CEB (chemically enhanced backwash) system
- Integration as standalone treatment or RO pre-treatment
- Commissioning, performance testing and operator training
Why specify with us
Low total cost of ownership
High-rejection membranes, correctly sized pre-treatment and efficient pumps reduce power draw, consumable spend and reject volume. We quote five-year operating cost alongside capex, because that is the number that actually matters.
Heavy-duty SS-304 / SS-316 build
Corrosion-resistant stainless chassis and wetted parts engineered for continuous 24/7 duty, with SS-316 specified where chlorides or process chemistry demand it.
Rapid on-site servicing & AMC
Pan-India installation and service, with written response times and escalation in the AMC rather than verbal assurances — because plant downtime, not the repair, is your real cost.
Custom TDS tuning
Systems engineered against your actual water analysis — brackish groundwater, municipal supply or heavy borewell input, including high-TDS configurations for 3,000+ ppm feed.
Treatment architecture
- 1
Pre-treatment module
Multigrade sand and activated carbon filtration strips suspended solids, turbidity and chlorine that would otherwise oxidise the RO membrane.
- 2
Softening / antiscalant dosing
Protects membranes from calcium and magnesium scaling. On hard feed water this stage is not optional — it determines membrane life.
- 3
High-pressure RO module
Heavy-duty booster pumps drive feed water through industrial spiral-wound membranes at 12-18 bar in an array sized for your recovery target.
- 4
Post-treatment disinfection
UV disinfection and ozonation, with mineral dosing where potable taste and consistency matter.
- 5
Microprocessor / PLC controls
Auto start-stop on tank level, dry-run protection, high and low pressure cut-offs, and timed membrane flushing — with data logging on industrial plants.
