Introduction

UF- ultrafiltration is a type of Physical Filtration in which Pressure removes Suspended Particles from water based on the pore size of the membrane. Its pores size varies from 10-100 nm and sometimes pore size can be measured by molecular weight cut-off (MWCO), expressed in Dalton, It gives an idea of which size molecules will pass through a membrane. Filtrations having smaller cut-off than UF are Nano-filtration and Reverse osmosis and Filtration having Large Pore size then UF is Microfiltration. Most of Uf plants are Run Automatic with the help of PLC. The lifespan of the UF membrane is 2 to 5 Years depending on inlet Water Quality. Because of high porosity, we have to apply less pressure compare to Nanofiltration and R.O.
