The original traditional ion exchange water treatment system with output capacity of 200 t/h has been retrofitted into a membrane water treatment system with output capacity of 320 t/h

the practical application shows that the membrane technology has many advatages: (1) The occupied area to be smaller

comparing with the traditional ion exchange water treatment system

the occupied area to be reduced about 3000 m2 ; (2) in the period of seawater poured backwards

the membrane water treatment system can still be in normal operation

the anually saved tap water hitting 1

5 million t; (3) the membrane technology to be simple

its automatic control can be easily realized; (4) the quality of output water to be high; (5) without discharge of waste acid and alkali

being advantageous for environmental protection.
