	ULTRA FILTRATION 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 ( TF™)
	Turbo Filtration™ 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 , seprating higher molecular particles TF™ 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 + Recycling of wastewater

	NANO FILTERATION Nano filtration is a pressure driven separation process. It is much the same as reverse osmosis. The key difference is the high degree of removal of monovalent ions, multivalent salts and low molecular weight organics in the reject. Reverse osmosis removes the monovalent ions at 98-99% level at 200 psi. Nano filtration membranes’ removal of monovalent ions varies between 50% to 90% depending on the material and manufacture of the membrane. There is variety of Nano filtration membranes available. Each type is particularly suited to a certain application and may not be acceptable to a different application.
