Ultra Filtration Plants
Membrane-based filtration that removes suspended solids, bacteria, and macromolecules — achieving consistent output quality regardless of feed water variation.
Membrane-based filtration that removes suspended solids, bacteria, and macromolecules — achieving consistent output quality regardless of feed water variation.
Overview
Ultra Filtration is a pressure-driven membrane separation process that operates at pore sizes of 0.01 to 0.1 microns — fine enough to remove suspended solids, colloids, bacteria, viruses, and high-molecular-weight organics while allowing dissolved salts and water to pass through freely.
HPT's UF systems are deployed as standalone treatment units or as pre-treatment stages ahead of Reverse Osmosis — extending RO membrane life and reducing operating costs significantly. Our UF plants use hollow-fibre or tubular configurations selected for your specific feed water characteristics.
How It Works
Raw or pre-screened water enters the UF system feed tank.
Cartridge or strainer filters remove large particulates that could damage membranes.
Feed water is pressurised through hollow-fibre membranes; solids, bacteria, and macromolecules are retained on the feed side.
Filtered water (permeate) passes through to the product tank or downstream RO system.
Automated backwash cycles and periodic chemical cleaning restore membrane flux.
Key Features
UF membranes provide a physical barrier — output quality is independent of feed water variation.
Skid-mounted systems with small footprint. Capacity scalable by adding membrane modules.
Dramatically reduces SDI of RO feed water, protecting downstream membranes and reducing replacement frequency.
Timed or pressure-differential triggered backwash cycles maintain flux without operator intervention.
Integrated CIP skid for periodic membrane recovery and extended membrane life.
Properly maintained UF membranes deliver 5–8 years of service life under normal conditions.
Applications
Industries Served
UF is the technology of choice wherever consistent output quality is non-negotiable — regardless of how much raw water quality fluctuates with rainfall, season, or process variation. Its compact footprint and modular design make it deployable in virtually any plant configuration.
Why Membrane?

Our Approach
Turbidity, SDI, TOC, and microbial analysis to select the optimal membrane configuration and pre-treatment.
Hollow-fibre, tubular, or spiral wound selection; flux, recovery, and CIP cycle design to your output spec.
Skid fabrication, site installation, commissioning, and post-handover O&M support under one contract.
HPT selects UF membrane configuration — hollow-fibre, tubular, or spiral wound — based on your feed water characteristics and downstream requirements. For RO pre-treatment applications, we design UF systems to achieve SDI values below 3, ensuring maximum RO membrane protection. For standalone applications, we design to the required output quality standard with minimum energy and chemical consumption.
