AI Technical Summary
The condensate produced by the salt production MVR unit has an alkaline pH and a high ammonium ion content, which easily leads to scaling of the equipment. Traditional methods use hydrochloric acid to adjust the pH value, which increases conductivity and reduces system operating efficiency.
The system employs a combination of a condensate tank, filter, cation exchanger, decarbonator, anion exchanger, and mixed ion exchanger. Scale is removed via a backwash pump to maintain the original water quality and prevent pH changes.
It improves condensate recovery efficiency, extends system operating time, maintains system stability, and increases water production rate.
