Membrane ultra-filtration unit

for wastewaterprocess water

Membrane technologies Microfiltration General introduction Microfiltration (MF) is a physical membrane separation technique, separating suspended materials, algae, and some microorganisms according to their particle size. Particles larger than the pores of the membrane (0.1 – 10 micrometers) are fully removed. Applied membranes can be flat-sheet, hollow fiber, tubular and spiral wound. The process can be pressurized or vacuum driven (submerged design). Fields of application • filtration of fruit juices, wines and beers; • metal recovery in a form of colloids • waste water treatment; • removal of suspended solids and some microorganisms; • pretreatment of desalination Ultrafiltration (UF) General introduction UF is usually used for removal of particles and macromolecules from raw water. As one of its most dominant place within any technologies, it is responsible for the pretreatment phase, followed by a RO installation. In case high suspended solids are present in the flow to be treated, UF is often integrated into the process, but additional pretreatment units (e.g. microfiltration) prior to UF might be required to prevent damage of the membrane units. Advantages • Constantly high product quality, • High TSS removal efficiency • Compact plant size, • 90-100% pathogen removal efficiency. Fields of application • microbiological pollutants removal from water, • industrial process water production • laundry waste water recirculation, • waste water treatment in membrane bio reactors.
