Reverse Osmosis watermakers can be used to remove dissolved solids including mineral salts and other inorganic chemicals from sea water. It is the desalination technology of choice of most commercial shipping and shore based communities. Desalinators, sometimes called watermakers, typically operate at pressures of 50 to 60 Bar depending upon the water temperature.
Sea water desalinators often operate in remote locations and harsh conditions. Our desalinators are engineered with proven durable components to ensure reliable operation and minimal down time. They are supported by factory trained technicians who are available for commissioning and routine maintenance.
Sea water contains approximately 35,000 milligram per litre of dissolved salts. The sea water is pumped into the reverse osmosis membranes at 50 to 60 Bar pressure. Approximately a third of the water passes through the membrane leaving the salt behind. Desalinator pure water usually contains less than 500 milligrams per litre. The remaing two thirds of the sea water is now concentrated in dissolved salts of approximately 52,000 milligrams per litre and is usually retrurned to the sea.
Reverse osmosis is not particularly suited to removing suspended solids such as silt or organic chemicals such as tannins. Additional water treatment methods may be required particularly when operating in turbid river esturies.
The reverse osmosis sea water desalinator units can be supplied as stand alone modules, skid mounted systems including pretreatment equipment, enclose cabinet models and transportable shipping containers.
