Tanker water that arrives muddy. Borewell water that turns cloudy after rain. Treated STP water that needs to be clean enough for flushing. RO membranes that foul within weeks. All of these Chennai problems have the same solution at their core: ultrafiltration. Intellect Aqua designs and installs UF plants in Chennai that remove turbidity, suspended solids, bacteria and cysts reliably, with very little water wasted.
What Ultrafiltration Does
A UF plant pushes water through hollow-fibre membranes with very fine pores. Particles, colloids, most bacteria and cysts are held back; dissolved minerals pass through. Regular automatic backwashes clean the membrane surface, and periodic chemically enhanced backwashes remove stubborn fouling.
Unlike RO, UF does not remove dissolved salts, does not need high pressure and does not produce a large reject stream. That makes it ideal where water is clear of excess salts but not clean enough to trust.
UF Applications in Chennai
Treating Tanker and Borewell Water
Many Chennai buildings depend on tankers whose water quality varies from load to load. A UF plant at the inlet removes mud, turbidity and bacteria, giving consistent clean water to overhead tanks. Combined with a water treatment plant for iron or hardness, it protects every tap in the building.
Pre-Treatment for RO
Chennai's high-TDS water often needs RO, and RO membranes hate fine particles and colloids. UF before RO dramatically reduces membrane fouling, extends membrane life and stabilises output — especially for industrial RO plants running on difficult feed water.
STP Water Reuse
Treated STP water often looks clear but carries fine solids and bacteria. UF after the STP raises quality so it can be confidently reused for flushing and cooling towers. See wastewater recycling in Chennai.
Process Water for Food and Beverage
UF removes bacteria and particles without changing mineral content — useful for food, beverage and some pharma processes.
UF or RO — Which Do You Need?
| Your water problem | Recommended |
|---|---|
| Muddy, cloudy, turbid water | UF |
| Bacteria or cysts with acceptable TDS | UF + UV |
| Salty or high-TDS water | RO (with UF pre-treatment if feed is dirty) |
| STP water for reuse | UF + disinfection |
| Industrial RO fouling quickly | Add UF before RO |
We decide after a water test. If RO is needed, we tell you; if UF alone will solve the problem, we will not oversell. See also RO plants in Chennai.
Benefits of a UF Plant
- Removes turbidity, suspended solids, bacteria and cysts
- Very high recovery — little water wasted
- Low pressure and low power use
- No routine chemical dosing for basic treatment
- Compact, skid-mounted design
- Keeps natural minerals in drinking water
How We Design UF Plants
We test turbidity, organics, iron and microbial load, and assess how variable your source is. Then we choose membrane type and area, flux rate, pre-filtration (disc, screen or sand filters), backwash and CEB frequency, and automation. For variable tanker supply, we size conservatively so the plant handles the worst loads, not just the average.
UF for Apartments That Depend on Tankers
For many apartments in OMR, Medavakkam, Pallikaranai and the southern suburbs, tankers are the main water source for months at a time. Residents see cloudy water, sediment in buckets and frequent choking of individual flat filters. A central UF plant installed between the sump and the overhead tanks solves this at the root. Every flat receives clear, filtered water, individual purifiers last longer, and the association has one system to maintain instead of hundreds of small filters.
We size the plant for the community's peak pumping rate and add a small buffer so overhead tanks fill quickly. Automatic backwash runs during low-demand hours so residents are not affected.
Running Cost of a UF Plant
UF is economical to run. Power use is low because the plant operates at low pressure. The main running costs are cleaning chemicals for periodic chemically enhanced backwash, pre-filter maintenance and eventual membrane replacement. Because recovery is high, very little water is lost — an important advantage when every litre of tanker water has a price.
Common UF Problems We Fix
When existing UF plants fail, the causes are usually missing pre-filtration, skipped chemical backwash, iron fouling or broken fibres. We test membrane integrity, clean or replace modules, correct backwash settings and add pre-treatment where needed.
Maintenance and AMC
UF needs routine backwash checks, chemical enhanced cleaning, integrity tests and pre-filter care. Our AMC in Chennai covers all of this, plus chemicals and membrane replacement when due.
