    Reverse Osmosis Water Testing

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached. Reverse Osmosis (RO) is a membrane process of purification which removes most of the the total dissolved solids (TDS) in water by reversing the natural process of osmosis. Pressure is applied to a TDS-concentrated solution against a semi-permeable membrane, causing pure water to diffuse through the membrane. RO has become an important process for a wide variety of applications including: medical, laboratory, desalination, industrial wastewater, Deionized (Dl) pretreatment, and drinking water.

    ADVANCEES - Advanced water treatment equipments for desalination

    Areas that have no or limited surface water or groundwater may choose to desalinate seawater or brackish water to obtain drinking water. Reverse osmosis is the most common method of desalination, Sea Water Reverse Osmosis (SWRO) is a reverse osmosis desalination membrane process that has been commercially used since the early 1970s. Because no heating or phase changes are needed, energy requirements are low in comparison to other processes of desalination, though still much higher than other forms of water supply (including reverse osmosis treatment of wastewater).

    Water treatment solutions for the desalination

    Our Filters are Highly Resistant to Corrosivity. Reverse osmosis is one of the most widely applied desalination technologies. Previous to the process of separtion of water from salt and minerals, seawater or brackish wter requires the elimination of large size particles in order to assure a good performance of reverse osmosis membranes. Our sand filters facilitate the removal of these suspended solids to avoid membrane fouling. In addition, after reverse osmosis process, water has to be remineralized through calcite filters to increase the alcalinity and hardness of desalted water and reduce its corrosivity to fit for human consumption, domestic use, industrial or irrigation.
