Membrane Deminarilisation

Reverse Osmosis :
Reverse Osmosis is a process by which a solvent (water) passes through a porous membrane in the direction opposite to that for natural osmosis when subjected to a hydrostatic pressure greater than the osmotic pressure.

The applications for membrane technology are numerous including treatment of water for drinking purposes, industrial process water treatment, water treatment for food and beverage processing, wastewater recovery, purification of home drinking water etc.t is also used for seawater and brackish water desalination and where the requirement is for ultra-pure water, such as semi-conductor industry, boiler feed water and medical / laboratory applications.

Utilising Reverse Osmosis prior to ion-exchange polishing plants dramatically reduces operating costs and regeneration frequency.

Membrane Filtration

Ultra Filtration :
Ultra Filtration is a process where solute ( particulates & macromolecules ) are separated by an induced pressure from a solvent (water) through a semi permeable membrane.

Ultra Filtration processes are currently preferred over traditional treatment methods for the following reasons :
Filtration levelPore sizeTarget Contaminants
Microfiltration 0.05-1.0 μm Particulate material like algae, Crypto, bacteria and clays.
Ultrafiltration 0.005 μm -0.5 μm All Substances removed by micro filters and ultra filters plus dissolved metals and salts
Nanofiltration 0.0005-0.01 μm All substances removed by microfilters and ultrafilters plus dissolved metals and salts.
Reverse Osmosis 0.0001-0.001 μm All substances removed by microfilters, ultrafilter, nanofilters plus smaller dissolved metals and salts.
