Characteristics of seawater desalination pretreatment filter

Seawater cannot be used directly because of its high salt content. At present, two methods are mainly used to desalinate seawater, namely distillation and reverse osmosis. Distillation method is mainly used in super large seawater desalination treatment and places rich in heat energy. Reverse osmosis membrane method is widely used because of its wide application…
