Which component is designed to enhance the recovery efficiency of a water system?

The permeate pump is specifically designed to enhance the recovery efficiency of a water system, particularly in reverse osmosis (RO) systems. This pump works by using the energy of the pressurized feed water to provide an additional force that helps to push the permeate (the purified water) more effectively when the system is operating.

By improving the flow of processed water to the storage tank, the permeate pump helps ensure that a greater volume of water is recovered as product water rather than being wasted as brine. This leads to a more efficient system, as it maximizes the usable water output in relation to the input. In essence, by reducing the reliance on the feed water pressure alone, the permeate pump can significantly enhance the overall efficiency of the water treatment process.

The other components listed, while essential for various functions in water systems, do not specifically enhance recovery efficiency in the same way. The pressure tank primarily stores water under pressure for immediate use, the filtration system focuses on removing contaminants from water, and the check valve prevents backflow within the system. While all these components are important, they do not directly contribute to increasing the amount of product water recovered.
