Thermal Desalination

Desalination is a sustainable answer to the problems of limited access to fresh water and BWA is proud to have been providing water additives for use in thermal desalination processes since 1973.

Thermal desalination is a complex process with many potential pitfalls. Controlling foam, preventing fouling and inhibiting the formation of scale all require constant monitoring and control. BWA provides thermal desalination water additives that address all of these potential problems and keep them from occurring. We provide water treatment options for both Multi Stage Flash (MSF) and Multi Effect Distillation (MED) desalination systems.

For foam control and tube wetting (MED), we offer Belite® M8 and Belite® AF10, liquid water additives that prevents foam during the distillation process. To prevent water fouling, we offer several scale inhibiting products: Belgard ® EV, EVN, EV2030, EV2035, and EV2050. These products keep calcium carbonate, calcium sulfate and magnesium hydroxide scaling from occurring in a wide range of environments and at different points in the thermal desalination process. We provide several options which are required to protect systems with multiple variables of design, heat flux, top brine temperature and seawater chemistry.

BWA also provides market-leading technical service and support with both on-site optimization of your process using fluorimetry and web-based tools focused on operational performance, monitoring, and feedback.
