Ultrafiltration (UF) is a membrane-based physical separation technology used for effective removal of suspended solids, turbidity, colloids, bacteria and high-molecular-weight organic compounds from water and treated wastewater.
UF membranes typically operate in the pore size range of 0.01 to 0.1 micron, making them highly suitable as a polishing stage or as pretreatment for advanced membrane systems.
UF systems are widely used in water and wastewater treatment applications to ensure low turbidity, controlled SDI and stable feed water quality for reuse and downstream processes such as Reverse Osmosis (RO). The system operates at relatively low pressure and incorporates periodic backwashing and chemical cleaning (CIP) to maintain long-term membrane performance.
Applications of UF Systems
Pretreatment before RO systems to protect membranes and improve recovery
Tertiary treatment in ETP and STP for improved effluent quality
Water recycling and reuse applications requiring low turbidity and SDI control
Process and utility water treatment systems
How S N Group of Environment Delivers UF Systems
At S N Group of Environment, UF systems are engineered with a strong focus on membrane protection, hydraulic balance and operational reliability rather than simple skid supply.
Our designs ensure stable performance, extended membrane life and consistent treated water quality under variable operating conditions.
