CLEAN WATER: Protecting How does Ultrafiltration Work? Ultrafiltration belongs to the family of liquid membrane filtration processes that include reverse osmosis, nanofiltration, ultrafiltration and microfiltration. Whereas reverse osmosis and nanofiltration reject inorganic molecules and ions present in water, ultrafiltration removes organic molecules such as proteins and polysaccharides with molecular weights of 10,000 and higher. It is also used for removal of particles such as viruses, bacteria, parasites and suspended solids from a fluid. The ultrafilter pore size can be from 0.005 micron to 0.1 micron, and a specific pore size range is selected for each
to achieve high removal efficiency of viruses and bacteria. The dead-end operation achieves very high recovery as all water fed during the filtration cycle is recovered as product. Periodic backwash using treated water dislodges solids accumulated in pores. This is followed by air flush of the outside surfaces to dislodge suspended solids sticking to the surface. A water wash then removes these solids from the modules. Chemically enhanced cleaning, in which a chemical is added to the backwash water, is also implemented to dissolve biofilm and colloidal solids in membrane pores. The modules are installed vertically to permit air flush and integrity test.

Ultrafiltration Membranes the world’s most precious resource project, if the size of the project justifies it. Modules are available in three lengths, each in a 0.225 m diameter to simplify installation. BIOREM ultrafiltration products are being used in applications ranging from drinking water, seawater desalination, sewage treatment, water recovery, and industrial processes such as power generation and mineral processing.
Key Features: ■ Highly uniform pore structure leading to consistent removal of viruses, bacteria and parasites ■ PVDF chemistry with high chlorine concentration resistance that permits aggressive cleaning and long life ■ Dead end operation with very high water recovery and low power use
■ Three module sizes for easy system retrofit with minimum modifications to existing infrastructure. ■ Ability exists to custom manufacture modules for retrofit of large systems

water, seawater desalination, sewage treatment, water recovery, and industrial processes such as mineral processing. With over 25,000 m3/h of installed capacity in thirty high profile applications on surface, recycle, ground and sea water sources, our engineers and technicians have the experience to make your project a success. We offer membranes in two chemistries. Our NIPS (Non-solvent Induced Phase Separation) membranes are asymmetric, are made from a highly hydrophilic PVDF chemistry, and deliver low fouling rates and low pressure drop. Our TIPS (Thermally Induced Phase Separation) membranes have highly uniform symmetric pores, and are five times stronger than NIPS membranes. This
