Aquatec Permeate

Aquatec’s Permeate Pump (ERP1000) is a simple, yet revolutionary, device.  Powered only by the hydraulic energy of brine water usually lost to the drain (meaning no electricity required), the Permeate Pump forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure. These pumps dramatically improve the efficiency of RO water production, reducing wastewater by up to 85%.  

In other words, if your current system requires 10 gallons of tap water to produce a gallon of pure water (10:1), adding a Permeate Pump should reduce this ratio below 3:1.

This pump can also bring storage tanks up to line pressure and then shut the system down when these tanks reach capacity, eliminating the need for a hydraulic shut-off valve.
