Ultra-Filtration (UF) Plants
Consistent, high-quality filtrate — membrane-based certainty for your process water supply.
Chemical-Free Pathogen & Colloid Removal
Ultra-Filtration (UF) represents the state-of-the-art in physical water clarification. It is a highly efficient membrane separation process designed to remove bacteria, viruses, colloids, suspended silt, and high-molecular-weight organic compounds from raw water feed.
Unlike conventional filtration, UF functions without requiring heavy coagulant chemistry, producing extremely consistent, high-purity filtrate regardless of seasonal raw water turbidity and feed variations. Hydrocare Engineers supplies, installs, and commissions premium Thermax UF skids across South Gujarat industrial estates.
How It Works
A simple three-step explanation of the low-pressure physical separation process.
Feed Pressurisation
Raw water is gently pressurized under low pressure (typically 1 to 3 bar) and fed into the membrane housings.
Barrier Filtration
Water passes through hollow-fibre or tubular membrane barriers containing microscopically graded pores of 0.01 to 0.1 microns.
High-Purity Permeate
Microorganisms, suspended solids, and colloids are blocked on the surface, while pure filtrate (permeate) flows out continuously.
Key Advantages Over Conventional Filters
Why modern industries are replacing pressure sand filters with advanced membrane systems.
Consistent Output Quality
Ensures a uniform filtrate quality and low turbidity output, even during severe seasonal surface/river water fluctuations.
Complete Log 6 Pathogen Removal
Achieves complete physical exclusion of bacteria, viruses, pathogens, and cysts, eliminating biological hazards.
Compact Physical Footprint
High packing density of hollow-fiber membranes requires up to 60% less space compared to sand filters or clarifiers.
Chemical-Free Operation
Separates contaminants without the addition of chemical coagulants, flocculants, or pH correction chemicals.
Ideal Pre-Treatment for RO
Consistently keeps Silt Density Index (SDI) < 3, drastically reducing RO membrane biofouling and cleaning frequency.
Industrial Applications
UF plants provide reliability across diverse industrial sectors and municipal schemes.
| Industrial Application | Process Benefit |
|---|---|
| Pre-treatment before RO Systems | Reduces feed SDI below 3, protecting expensive reverse osmosis membranes from colloid clogging. |
| Pharmaceutical Process Water | Produces bacteria and pyrogen-free water, suitable for sterile loops and chemical washing. |
| Potable Water Schemes | Delivers safe, pathogen-free drinking water for residential colonies, commercial buildings, and hospitals. |
| Tertiary ETP / STP Treatment | Clears secondary treated wastewater effluent to reach process-reuse quality, supporting zero-discharge. |
| Surface / River Water Filtration | Successfully handles spikes in river water turbidity, organic carbon, and colloidal silica. |
