PRETREATMENT

Virtually all steam producing boilers require properly pretreated feedwater. While sodium zeolite softening is still the most common pretreatment for scale control in low to medium pressure boilers, the need to conserve energy, reduce treatment costs, and improve steam purity is now requiring other pretreatment approaches. Even returned condensate, often the purest source of makeup water in the plant is often polished before it enters the boiler.

ChemTreat staff engineers have extensive experience with all types of pretreatment equipment, including deaerators, softeners, demineralizers, reverse osmosis, EDI/EDR, and condensate polishers. In addition, we have personnel who are experts with hot process lime and lime/soda softening and in-line filtration pretreatment. We can help enhance zeolite softening with RO membranes, replace hot process softening with other options and optimize regeneration and pretreatment costs with competent plant audits and surveys.
