Ultrafiltration Membrane Technology Water Treatment

REKPRO offer latest UF semipermeable membranes can play an important role in water purification because of its compactness and efficiency Ultrafiltration (UF) is a water purification process in which water is forced through a semipermeable membrane. Suspended solids and high-molecular-weight solutes remain on one side of the membrane, the retentate side, while water and low-molecular-weight solutes filter through the membrane to the permeate side. UF offered by REKPRO can remove most organic molecules and viruses, as well as a range of salts. It has gained popularity because it produces a stable water quality no matter the source water, has a compact physical footprint, removes 90-100% of pathogens, and does not require chemicals, except for cleaning membranes.

Where to use UF Technology ?
  • Drinking water application
  • Sewage Treatment Plant - Final Post Treatment
  • Grey Water Treatment systems - Final Post Treatment
  • Car Wash industry
  • Sediment Particle separation application’s in various used industries
History of UF Technology :

UF was first described at the end of the 19th century, but the practical start of ultrafiltration as a separation process came in 1963, coming on the heels of the discovery of the asymmetric cellulose acetate reverse osmosis membrane in the 1950s, and MIT’s discovery of polyelectrolyte complex hydrogels at the beginning of the 1960s. Modern membrane technology started in the late 1990s, when polymeric membrane chemistry and processing techniques began to be used in membrane manufacturing. These new materials and manufacturing methods made UF an efficient, competitive process for water treatment. In 2019, the global ultrafiltration membrane market size was $5.3 billion dollar. While the pandemic put a damper on investment in 2020, the market is projected to recover in 2021 and grow substantially moving forward, with efficiency advancements and increasing water safety regulations expected to drive adoption. UF Membrane Characteristics The pore size of ultrafiltration membranes ranges from 0.1 to 0.01 microns, but “molecular weight cut-off” (MWCO) is now one of the best ways to describe UF membranes. The science of MWCO is the molecular weight at which 90% of a macromolecular solute does not pass through the membrane. UF’s range of filtration lies between microfiltration and nanofiltration. The membranes used in ultrafiltration require maintenance cleaning to prevent fouling with solids, scaling, and microbiological agents such as microbes and algaes The Typical UF applications include: Treatment and recycling of wastewater and industrial process water Removal of particulates and macromolecules (for example, 90-95% arsenic removal) for potable water production Standalone systems Augmentation or replacement of secondary and tertiary filtration stages in existing water treatment plants Filtration of paper pulp mill effluent Food and beverage industry applications Water softening
