Processes Used For Different Water Quality Requirements

According to the water quality requirements, the process is usually used

1.The conductivity of the water produced is 10-20 μs/cm

The conductivity of the production water is required to be 10~20μs/cm, and RO pretreatment + first-stage reverse osmosis (chemical) is used.

2.Conductivity of water production 2~9μs/cm

Conductivity of water production 2~9μs/cm, using RO pretreatment + secondary reverse osmosis (pharmaceutical, chemical) or using RO pretreatment + softening + primary reverse osmosis +EDI (pharmaceutical, chemical)

3.The conductivity of produced water is less than 0.2~2μs/cm

The conductivity of the water produced is less than 0.2~2μs/cm, using RO pretreatment + one stage reverse osmosis + mixed bed

4.Water production resistance 5~13 mω.cm

Water production resistance 5~13 mω.cm, using R0 pretreatment + softening + one stage reverse osmosis +EDI

Or use RO pretreatment + secondary reverse osmosis +EDI (pharmaceutical, chemical, electronics, power generation)

5.Water production resistance 13~17 mω.cm

Water production resistance 13~17 mω.cm, using R0 pretreatment + softening + one stage reverse osmosis +EDI+ mixed bed
Or use RO pretreatment + secondary reverse osmosis +EDI+ mixed bed (pharmaceutical, chemical, electronics, power generation)

6.Water production resistance 18 mω.cm

Water production resistance 18 mω.cm, using RO pretreatment + two stage reverse osmosis +EDI+ mixed bed + sterilization + nitrogen seal.
