Ultra filtration systems with a membrane diameter of 0,02 micron structure without use of chemicals turbidity, bacteria, viruses and other microorganisms, suspended solids up to 99% of that can go at a rate of membrane filtration systems. 

Ultra-filtration is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). 

Ultra-filtration technology uses a membrane barrier to exclude very small particles, including bacteria, viruses and colloids. Advantages of UF compared to conventional treatment such as clarifiers and media filters, are its high tolerance to feed water quality upsets, absolute barrier and improved water quality.
