Membrane Filtration: Microfiltration - FCT Water Treatment

Because microfiltration is a physical separation process, it can remove contaminants from water without the need for harsh or expensive chemicals. Its larger pore size makes it excellent for a 'first pass' filtration, to partially filter water before sending it on for further filtration, such as ultrafiltration or reverse osmosis.
