Marine seawater desalination machine
Marine seawater desalination machine
Product details

The marine seawater desalination machine is specially designed considering the issue of draft on board, and adopts reverse osmosis membrane separation technology for seawater desalination and desalination. It is small in size, light in weight, and easy to install, and can be installed in narrow and crowded cabins, decks, corridors, and other places.

Desalination process of marine seawater desalination equipment:

Computer room seawater pump → sterilization system → pipeline booster pump → bag filter → precision filter → ultrafiltration system → high-pressure pump reverse osmosis system → ultraviolet sterilizer → intermediate booster pump → primary filtration → secondary filtration → high and low pressure switch → high-pressure pump → small reverse osmosis system → activated carbon filter → ultraviolet sterilizer → direct drinking water

Working principle of seawater desalination equipment:

The marine seawater desalination machine adopts reverse osmosis membrane separation technology for seawater desalination and desalination. The reverse osmosis desalination method uses a "semi permeable membrane" that only allows fresh water to pass through and does not allow salt to pass through. By using a high-pressure pump to apply pressure to seawater, the fresh water in the seawater passes through the membrane and goes to the fresh water side, hence it is called reverse osmosis or reverse osmosis.

Parameters of marine seawater desalination equipment

Inlet salt content: ≤ 40000mg/L Inlet water temperature: 0~45 ℃
Specific gravity of seawater: 1.025 Seawater viscosity: 1.05mm2/s (25 ℃)
Inlet pH range: 2.0~11.0 PH range of effluent: 6.5~8.5
Salt content in effluent: ≤ 700mg/1 System desalination rate: ≥ 98.5%
Outlet water quality: meets the GB5749-2006 standard for drinking water quality
Outlet pressure:> 0.15MPa System recovery rate: * 30% (depending on temperature and water quality)
Piston pump oil: SAE90 industrial gear oil Oil consumption of plunger pump: 1.5 liters/time
Power supply: 380Vac/50Hz High pressure pump motor power: 5.5-18.5KW

Price of marine seawater desalination equipment:

The quotation for marine seawater desalination equipment is mainly based on the daily processing of fresh water tons. However, for ordinary marine seawater desalination equipment, the daily processing of fresh water tons is not much, and the price is about one or two thousand yuan. If it is a marine seawater desalination equipment used by large ships, the cost is higher, and specific details need to be communicated with our technical personnel.
