Boiler feed water treatment plants utilize several contaminants that remove are hardness, iron, silica, sodium and chlorides. The basic process removes the suspended matter before reverse osmosis (dissolved solids reduction) and finally EDI polishing. RO pre-treatment commonly consists of coagulation, flocculation, clarification, sand filtration, etc. Essentially 100% of the suspended particles must be removed in the pre-treatment. RO removes approximately 99+% of dissolved salts and solids in water.

BOILER FEED WATER PURIFICATION PROCESS

bow the sex toy work engine,EDI is the final polisher. Continuous Electrodeionization (CEDI or EDI) is a process that uses electricity to produce ultra-pure deionized/demineralized water. While it utilizes ion exchange resin, it is continuously self-regenerated without the use of chemicals (i.e. caustic and acid used with conventional ion exchange systems).

There are a number of advantages to EDI system versus mixed bed (IX):
  1. Easier to obtain permits
  2. Green technology – chemical free process
  3. Lower operating costs
  4. No hazardous waste (no neutralization sump/system required)
  5. No handling, disposal, or storage issues/concerns
  6. Safer
  7. Smaller footprint/space requirement

The boiler feed industry standard is moving toward reverse osmosis RO pretreatment and EDI versus conventional treatment with ion exchange. Particularly in the United States where it is becoming difficult to obtain permits for the hazardous chemicals (storage and disposal). We have boiler feed water plants and systems utilizing RO-EDI technology in California, Hawaii, Venezuela, etc.
