Micron Cartridge Filtration

The principle of micro filtration is physical separation. The extent to which dissolved solids, turbidity and microorganisms are removed is determined by the size of the pores in the membranes. Substances that are larger than the pores in the membranes are fully removed. Substances that are smaller than the pores of the membranes are partially removed, depending on the construction of a refuse layer on the membrane.

Micro filtration is pressure-dependent processes, which remove dissolved solids and other substances from water to a lesser extent than nano filtration and Reverse Osmosis.

Membranes with a pore size of 0.1 – 10 µm perform micro filtration. Microfiltration membranes remove all bacteria. Only part of the viral contamination is caught up in the process, even though viruses are smaller than the pores of a micro filtration membrane. This is because viruses can attach themselves to bacterial biofilm.

Micro filtration can be implemented in many different water treatment processes when particles with a diameter greater than 0.1 mm need to be removed from a liquid.

Examples of micro filtration applications are cold sterilization of beverages and pharmaceuticals, • Clearing of fruit juice, wines and beer, Separation of bacteria from water (biological wastewater treatment), Effluent treatment, Separation of oil/ water emulsions, Pre-treatment of water for nano filtration or Reverse Osmosis, Solid-liquid separation for pharmacies or food industries.
