Osmosis membranes - Import export

Reverse osmosis is the finest level of filtration available. The reverse osmosis membrane acts as a barrier to all dissolved salts and inorganic molecules, as well as organic molecules with a molecular weight greater than approximately 100. Water molecules, on the other hand, pass freely through the membrane creating a purified product stream. Rejection of dissolved salts is typically 95% to greater than 99%. Classification of brackish water: • Low salinity brackish waters: up to 5.000 ppm • High salinity brackish waters: between 5.000 - 15.000 ppm • Sea water: up to 45.000 ppm Reverse osmosis is a technology that is used in the production of ultrapure water for use in the semiconductor industry, power industry (boiler feed water), and medical/laboratory applications. Utilizing reverse osmosis prior to ion exchanger dramatically reduces operating costs and regeneration frequency of the Ionen exchanger plant.

Media filter is used to reduce the level of suspended solids (turbidity) in feed water. Suspended solids consist of small particles such as silt, clay, grit, organic matter, algae and other microorganisms. Feed water that is high in suspended solids can cause a high pressure drop and reduce the effectiveness of downstream equipment such as reverse osmosis membranes and ion exchange beds.
