A reverse osmosis plant is a manufacturing plant where the process of reverse osmosis takes place. Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective," this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.
Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules.
Ultra filtration is used for the separation of suspended solids, colloids, bacteria and virus. This technique uses membranes with pore size between 1-100nm.
L.D Engineering design and build tailor-made ultra filtrationplants.
Our UF plants are build with hollow fiber outside-in membranes, up to 100 m3/h, to purify surface or groundwater from suspended solids, colloids and all kind of micro-organisms such as bacteria, virus, protozoa, germs and larvae.
Ultra filtration is also commonly use as a Reverse Osmosis plant pre-treatment.
