Pretreatment equipment is used to remove impurities from water to reduce the problems associated with those impurities and to reduce dependence on chemical treatment. Various pretreatment technologies are used for boilers, cooling towers, closed loops, heat recovery steam generators, and process water applications.
Some pretreatment systems include:
- Sodium Zeolite Softening
- Sodium Chloride Dealkalization
- Weak Acid / Strong Acid Ion Exchange
- Split Stream Softening
- Demineralization by Ion Exchange
- Countercurrent Ion Exchange
- Acid Dealkalization
- Cold Lime Softening
- Hot Process Softening
- Sand Filter
- Anthracite Filter
- Carbon Filter
- Manganese Greensand Filter
- Reverse Osmosis
- Ultrafiltration
- Nanofiltration
- Microfiltration
- Electrodialysis (ED), Electrodialysis Reversal (EDR)
- Continuous Deionization (CDI)
