&Weihai ton ship water production device Since the middle of the century, seawater desalination technology has developed rapidly with the intensification of the freshwater resource crisis. Seawater desalination is an effective strategic way to solve the problem of freshwater resource shortage. For maritime transportation, especially ocean transportation, in order to increase the load and reduce the amount of fresh water carried, ships are basically equipped with seawater desalination devices (commonly known as water generation devices) to increase the economy and endurance of ship operations.
The reverse osmosis membrane method uses a semi-permeable membrane that only allows solvents to pass through but does not allow solutes to pass through to separate seawater and fresh water. Under normal circumstances, fresh water diffuses to the seawater side through the semipermeable membrane, causing the liquid level on the seawater side to gradually rise until it reaches a certain height. This process is called osmosis. At this time, the static pressure of the water column above the seawater side is called osmotic pressure. If an external pressure greater than the osmotic pressure of seawater is applied to the seawater side, the pure water in the seawater will reverse osmosis into the freshwater. The reverse osmosis membrane method can remove more than % of soluble salts and more than % of colloidal microorganisms and organic matter from water. The biggest advantage of reverse osmosis is energy saving. Its energy consumption is only / of electrodialysis and / of distillation.
The process flow of the reverse osmosis membrane method is: raw water&rrr pretreatment system&rrr high-pressure water pump&rrr reverse osmosis membrane module&rrr purified water. Among them, the pretreatment system can adopt rough filtration, activated carbon adsorption, fine filtration, etc., depending on the water quality of the raw water and the effluent requirements. Fine filtration is essential and is established to protect the reverse osmosis membrane and extend its service life. In addition, the composite membrane It is very sensitive to free chlorine in water, so the pretreatment system is usually equipped with activated carbon adsorption.
