GPT - Ultrafiltration Membrane System for Water Treatment
The Ultrafiltration (UF) Membrane System by Green Pebble Technologies is designed for effective water and wastewater treatment. Utilizing a low-pressure membrane filtration process, it efficiently removes suspended solids, colloids, bacteria, and viruses with typical pore sizes of 0.05 to 0.3 microns. This system operates under pressures ranging from 3 to 8 barg (300 to 800 kPa), enabling the passage of water and low molecular weight solutes while rejecting larger particles. The proprietary design eliminates the need for chemical-intensive treatments, which enhances its sustainability and modularity. The hollow fiber configuration supports both inside-out and outside-in water flows, ensuring high water flux, minimal fouling, and long membrane life. It's an efficient pretreatment stage for nanofiltration and reverse osmosis, offering adaptability for diverse water sources and reducing operating costs. Comprised of materials like PES or PVDF, the system provides a range of size options and features components constructed from UPVC, benefiting sectors that demand consistent water quality.
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.
