Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation , accessible drinking water , public and private aquariums , and the safe use of ponds and swimming ...
The permeate water from a NF separation is demineralised and may be disposed to large changes in pH, thus providing a substantial risk of corrosion in piping and other equipment components. To increase the stability of the water, chemical addition of alkaline solutions such as lime and caustic soda is employed.

Fouling of a membrane in different steps 1–5. 1) virgin membrane 2) pore narrowing 3) pore blocking 4) cake layer formation 5) cleaned membrane Membrane fouling is a process whereby a solution or a particle is deposited on a membrane surface or in membrane pores in a processes such as in a membrane bioreactor, [1] reverse osmosis, [2] forward osmosis, [3] membrane distillation, [4 ...
Ultrafiltration can be used for the removal of particulates and macromolecules from raw water to produce potable water. It has been used to either replace existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems employed in water treatment plants or as standalone systems in ...
