What component ensures water quality by diverting excess TDS to waste?

The product divert valve is a crucial component in water purification systems that helps maintain water quality by managing the total dissolved solids (TDS) levels in the output water. When the concentration of TDS in the product water exceeds a predetermined threshold, the product divert valve activates to redirect some of the water to waste. This mechanism prevents the delivery of overly concentrated water from the system, ensuring that only water that meets quality standards is made available for use.

The operation of the product divert valve not only protects the quality of the water being processed but also enhances the longevity and efficiency of the overall system by preventing the circulation of contaminated or low-quality water. This is particularly important in settings such as dialysis, where precise water quality is essential for patient safety.

In contrast, the other components mentioned fulfill different roles; for example, a pre-filter serves to remove larger particles before they can enter the main filtration system, a TDS meter measures the concentration of dissolved solids without actively managing them, and a pressure regulator ensures consistent water pressure but does not specifically address TDS levels.
