Applications:

1. Feed water of steam boiler, hot water boiler exchanger,evaporative condenser,air conditioner ect.

2. Domestic water of hotel, restaurant, office building, apartment ect;

3. Water softening for food and beverage, brewing, washing, printing, chemical and medicine ect.

Working process includes:

Operating Principle:

Multimedia filter and activate carbo filter are pre-treatment filters which is done by filter media (quartz sand, activate carbon, gravel, anthracite..etc) to purify raw water first then enter into water softener.

As Calcium and Magnesium are the main substances for the hardness water. In order to exchange Ca2+, Mg2+(main component of scale), cation exchanger (softener) is needed. After running for a long time, resin shall be regenerated by sodium chloride(NaCl).

Reaction equation of softening (R is resin):

2RNa+Ca2+=R2Ca+2Na+ 2RNa+Mg2+=R2Mg+2Na+

Reaction equation of regeneration:

R2Ca+2NaCl=2RNa+CaCl2 R2Mg+2NaCl=2RNa+MgCl2

Flow chart:

Discription:

1.In order to cut down the cost, can change into manual control system.

2.If the device run for 24 hours continuously, can choose two sets alternately, one for spare one

for operating.

3.According to the outlet water's quality, can add some device before water softener.

Like Multimedia Filter(effectively remove sand, iron rust, colloid and seston) and Active Carbon Filter

(effectively remove remained chlorine and pesticides as well as pigment, odor, organice).

4.Outlet water's quality can reach state standard of low pressure boiler water.
