Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This separation process is used in industry and research for purifying and concentrating macromolecular (103 - 106 Da) solutions, especially protein solutions. Ultrafiltration is not fundamentally different from microfiltration or nanofiltration, except in terms of the size of the molecules it retains. Mostly, ultrafiltration is applied in cross-flow mode and separation in ultrafiltration undergoes concentration polarization. UF membranes typically have pore sizes in the range of 0.01 - 0.10 µm. The smaller the nominal pore size, the higher the removal capability.
TURBO FILTERATION ( TFTM)
Turbo FiltrationTM is one of the patented technologies of Wock-Oliver, which has been done after years of R&D.
Its low pressure UF and is devised where re-cycling of effluent is required, separating higher molecular particles
TFTM has been utilised in variety of industry for re-cycling i.e. STP, Textile, paper, ceramics, pharmaceuticals, edible oil water treatment, etc.
Advantages
High removal capability for bacteria and most viruses, colloids and silt
Does not introduce any chemicals to the water
Produces no by-products
Does not alter the taste, pH or other properties of the water
Easy and cost-effective to install and maintain without any special training
Application
At home/work place for pretreatment of water supply before domestic use
