DEMINERALIZATION SYSTEM

* FEATURES
- Regeneration effect is very high.
- The silica removing capacity is veryhigh.
- It can show flexible response to changes in the quality of the rawwater.
- Prices are reasonable and manufacturing is easy.
- Operation is simple.

* KINDS
There are two kinds of demineralizers :

- DOUBLE BED DEMINERALIZER

* Two-bed and two-tower type : H-tower is linked to OH- tower.

* Two-bed and three-tower type : H-tower, degasfier and OH-tower arelinked to one after another.

- MIXED BED DEMINERALIZER

Type

Application

Quality of Treated water

Use of

Treate water

Mixed bed

When the raw water contains little salt and the quality of treated water is high. It is necessary to operate the demineralizer at a constant rate if SiO₂is guaranteed.

Electricity conductivity is less than 2

μΩ/cm and silica containing ( SiO₂)

is less than 0.3ppm.

Polymerization

water,

cooling water and

washing water

2-Bed and

2-Tower

(type1)

When the raw water contains little HCO₃.

Electricity conductivity is less than

10μΩ/cm. SiO₂is not removed

Boiler water,

process water,

washing water.

2-Bed and

2-Tower

(type2)

When the raw water contains little HCO₃.

Electricity conductivity is less than

10μΩ/cm and the containing of

silica as SiO₂(SA2OA) is less than

0.2ppm.

Boiler water,

process water,

washing water.

2-Bed and

3-Tower

(type1)

The most general treatment method.

Electricity conductivity is less than

10μΩ/cm and the containing of

silica as SiO₂is less than 0.2ppm

(SA20A)and less than0.1ppm

(SA10A).

Boiler water,

process water,

washing water.

2-Bed and

3-Tower

(type2)

When the raw water contains much CI₂SO₄and little SiO₂. The regeneration effect is excellent because WA is mixed in the anion tower.

Electricity conductivity is less than

10μΩ/cm and the containing of silica

as SiO₂is less than 0.5ppm.

Boiler water,

process water,

washing water.

2-Bed and

3-Tower

(type3)

When the raw water contains much HCO₃

and is very hard.

Electricity conductivity is less than

10μΩ/cm and the containing of

silica as SiO₂is less than 0.2ppm.

Boiler water,

process water.

2-Bed and

3-Tower

(type1)with

Polisher

This the combination of the 2-Bed and

3-tower deminralizer(type-1) and the mi-

xed bed demineralizer. This can produce water with higher purity.

Electricity conductivity is less than

1μΩ/cm and the containing of silica

as SiO₂is less than 0.2 ppm.

Boiler water,

process water.
