Ultrafiltration
Assured and Reliable Purification for Water and Wastewater Treatment Plants
Ultrafiltration (UF) is a low-pressure membrane filtration process for water and wastewater treatment to remove suspended solids, colloids, bacteria and viruses.
UF is typically a hollow fiber configuration where feed water flows either inside the fiber (inside-out) or outside (outside-in) of the fibers. Typical pore size of the UF membrane is 0.05 to 0.3 microns and operating pressure is in the range of 3 to 8 barg (300 to 800 kPa).
Suspended solids, particles, colloids and solutes of high molecular weight are effectively rejected, while water and low molecular weight solutes pass through the membrane.
GPT’s proprietary UF membrane system removes the need of spacious and chemical-consuming coagulation, flocculation and settler unit operations and thus it is compact, modular and sustainable. Ideally UF is placed as a pretreatment to Nanofiltration (NF) or Reverse Osmosis (RO) system.
GreenPebble Technologies uses custom-made UF modules that are giving high water flux, less fouling, longer membrane life and cost advantage.
Our Ultrafiltration (UF) membrane and system provides flexibility to operate in a range of conditions that can be optimized for a specific water source to reduce operating costs.
