Microfiltration (MF)

Microfiltration (MF) is the most basic form of thin layered semi-permeable membrane based process to treat water and wastewater. MF process can be used to remove suspended solids, pathogens and other macromolecular compounds which are responsible for bad taste, odor or color.

​

The main driving force for the separation is hydraulic pressure (typically 1-4 barg) applied to the feed side. The pore size of MF membranes is in the range of 0.03 to 10 microns.

​

GPT's MF products are made from a robust and efficient polymeric material. It gives enhanced product water quality with significantly less chemical and energy usage. 

​

There is growing concern over effective pretreatment of influent stream prior to inlet to water recovery stages of Nanofiltration (NF) and Reverse Osmosis (RO). Having MF as pretreatment helps in limiting number of chemicals that are added to feed stream. By removing pathogens, MF process can help achieve the objective of reducing chemical addition processes such as chlorination and dichlorination.

Applications of Microfiltration (MF)

• Pretreatment or Concentration of beverages and pharma products

• Recovery of biologically aerated sewage water

• Industrial effluent treatment

• Oil-Water Separation

• Pretreatment of nanofiltration or reverse osmosis in desalination

• Solid-liquid separation for pharma and biotech industries
