Ultrafiltration Plant (UFP)
Ultrafiltration is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes. Ultrafiltration is frequently used to pretreat surface water, seawater and biologically treated municipal water upstream of the reverse osmosis unit.27-Feb-2015
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, while water and low-molecular-weight solutes filter through the membrane to the permeate side.
Ultrafiltration with 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, while water and low-molecular-weight solutes filter through the membrane to the permeate side.
UF 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.
UF Membrane Characteristics
The pore size of ultrafiltration membranes ranges from 0.1 to 0.01 microns,
- 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 industryapplications
- Water softening
Advantages of UF
Ultrafiltration technology is able to do more work in 50% less space than legacy processes, which is why UF pretreatment was chosen as standard equipment for all of Fluence’s compact NIROBOX™ seawater and brackish water modular desalination units.
UF pretreatment can extend the life of reverse-osmosis membranes in the treatment of high-silt density index (SDI) waters. They require lower investment, deliver reduced operating costs, use no coagulants, and require little chemical use.
Standalone stainless steel skid-mounted Fluence UF units are available for a variety of uses, such as reverse osmosis (RO) pretreatment, surface water clarification, treatment of high-SDI groundwater, seawater pretreatment, arsenic removal, primary and secondary treatment of effluents for reuse, and bacteriological treatment for mineral water.
