Reverse osmosis is a high-efficient technique for dewatering process streams, concentrating/separating low-molecular-weight substances in solution, or cleaning wastewater. It has the ability to concentrate all dissolved and suspended solids.
Nano-filtration is selected when Reverse Osmosis and Ultrafiltration are not the correct choice for separation. Nanofiltration can perform separation applications such as demineralization, color removal, and desalination.
Ultrafiltration is a selective fractionation process using pressures up to 145 psi (10 bar). It removes bacteria, viruses, suspended solids and solutes of molecular weight greater than 1,000.
Microfiltration is a low-pressure cross-flow membrane process for separating colloidal and suspended particles in the range of 0.05-10 microns. Microfiltration is used for fermentation, broth clarification and biomass clarification and recovery.
Membrane Bio-Reactor is a combination of two basic processes – biological degradation and membrane separation – into a single process where suspended solids and microorganisms responsible for biodegradation are separated from the treated water by membrane filtration unit.
