What does the product divert valve do when the TDS alarm limit is reached?

The product divert valve plays a crucial role in maintaining water quality and system integrity when the total dissolved solids (TDS) alarm limit is reached. When this alarm is triggered, indicating that the concentration of dissolved minerals or contaminants in the water has exceeded acceptable levels, the product divert valve automatically diverts the flow of water. This diversion typically sends the water to the drain rather than allowing it to continue into the system or other components where it could cause harm or compromise the purity of the treated water.

By directing the non-compliant water to the drain, the system helps to prevent the delivery of water that does not meet the quality standards, ensuring that only water appropriate for use is processed further or delivered to the end-users. This function is essential for protecting downstream processes and maintaining compliance with safety and quality regulations in water treatment applications.
