Containerized seawater desalination systems are becoming more and more popular for people living on islands and pure water supplying of tourism, suburbs and emergencies, etc. It produces pure water in a very short time that obviously makes efficiency. The systems mainly include electric controlling systems, chemical dosing systems, pretreatment, reverse osmosis filtration and backwashing systems, etc.

1.    PretreatmentMark: Other sizes and capacities are customized.

Pretreatment is a key part to protect the RO systems running stably and long no matter for seawater desalination, but also for brackish water desalination. Here are the main parts that we have to fully consider for making the pretreatment proposals:

a.     Abundant germ, bacteria and algae. Their propagation and fast growth not only brings a lot of trouble to intake devices, but also directly interfere in desalination equipments and pipes normal running.

b.    Periodical tide. It brings a lot of sediment and makes the turbidity be high, which makes the pretreatment unstable.

c.     Corrosivity. All equipments, valves and pipes should have corrosion resistance.

2.    Reverse Osmosis Seawater Desalination

Seawater has high dissolved salt and high hardness, which brings big corrosion to equipments. And the big water temperature range makes the seawater desalination systems much more complicated than other desalination systems. The project investment and power consumption are much higher too. In this case, the elaborative engineering seems very important to reduce the investment, power consumption cost and system running cost.

Waterland, as a water solution team, provides special and elaborative engineering for all area seawater desalination. We promise to make your coastal life happy with pure water.
