Demineralization System (TB/MB DI )

Demineralization system

1) Feed water Pumps
2) Multi-media filter units
3) Activated Carbon filter units
4) Strong Acid Cation units
5) Strong Base Anion units
6) Mixed Bed units

Demineralizer accessories include:
1) Cation Regeneration skid
2) Anion Regeneration skid
3) Mixed bed Regeneration skid

This system receives feed water and then pumps it into the Multi-media Filters and the Activated Carbon Filters through Feed Water pumps; Each rated at 66 gpm max at 50psig (15m3/hr @ 3.5 barg). The water then enters the Multi-media Filters and the Activated Carbon Filters. Each filter is rated for a service flow rate of 66gpm (15m3/hr) and a backwash flow rate of 66gpm (15m3/hr).

The water then enters the Strong Acid Cations each rated for Service flow of 66 gpm (15m3/hr). These units remove Cationic ions from the water. Then the water enters through the Strong Base Anions. Again, these are rated for 66 gpm (15m3/hr) flow rate each. The Strong Base Anions remove Anions from the water stream.
The last equipment to process the water is the Mixed Bed units. These units contain both Anion and Cation resin mixed together. This mixed resin polishes the water, greatly reducing the conductivity level.
The feed pumps provide regeneration water to the regeneration skids. Three different regeneration skids are supplied with the plant. One Cation regeneration skid, one Anion regeneration skid and one mixed bed regeneration skid. They each provide the necessary amount of dilute chemical to the demineralization vessels to regenerate the resins contained inside. The mixed bed units also need mixing air. The compressed air is used during regeneration to the resin after it has been regenerated.
