The process
Treatment plants evaporate reject streams with MVR, scrub odour from the tanks, and aerate biological stages with blowers. Corrosion resistance throughout.
The gas
Saturated vapour, often with dissolved solids and a low pH. Wetted parts in stainless steel, a shaft seal rated for the vapour, drain points and a casing designed for condensate.
Selection for this process
