Belmar called on Compagnie Hydrotechnique to supply an osmosis plant for an oil customer in West Africa.
Standing 2 m high and weighing almost 800 kg, this osmosis unit is actually a large watermaker.
Installed on board a ship, this machine produces fresh water from seawater.
Similar to a karcher pump, the machine draws in filtered seawater and sends it through the watermaker's membranes at a pressure of around 60 bar (high pressure). The membrane behaves like the pores in the skin, which dilate with temperature and allow particles of varying size to pass through (this is known as reverse osmosis desalination). It blocks not only salt crystals, but also bacteria and certain viruses present in salt water.
On average, for every 100 L of water drawn, a watermaker produces 10 L of fresh water.
Thanks Jamy!
