Boiler feed water

Boiler Feed Water Treatment Plants

Boiler feed water treatment plants remove hardness, iron, silica, sodium and chlorides from a variety of contaminants. The basic process is to remove suspended solids before reverse osmosis (reduction of dissolved solids) and final EDI polishing. RO pretreatment typically includes coagulation, flocculation, clarification, sand filtration, etc. 100% of suspended particles must be removed during pretreatment. RO removes approximately 99%+ of dissolved salts and solids from water.

Our water treatment technologies for boiler feed water solutions include:

Nanofiltration Systems

Reverse Osmosis Systems

Water Softeners

Deionized Water Systems

Industrial Ultrafiltration Systems

Boiler Feed Water Purification Processes

EDI is the final polishing step. Continuous Electrodeionization (CEDI or EDI) is a process that uses electricity to produce ultrapure deionized/softened water. Although it uses ion exchange resins, the resins can continuously regenerate themselves without the use of chemicals (such as alkali and acid used in traditional ion exchange systems).

EDI systems offer many advantages over mixed bed (IX):

Easier to obtain permits

Green technology – no chemical processes

Lower operating costs

No hazardous waste (no neutralization tanks/systems required)

No handling, disposal or storage issues/concerns

Safer

Smaller footprint/space requirements

Industry standards for boiler feed water are moving toward RO pretreatment and EDI rather than traditional ion exchange treatment.
