Aquatec’s original Permeate Pump (ERP1000) is a simple, yet revolutionary, device.
Powered only by the hydraulic energy of brine water usually lost to the drain (i.e. 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 R.O. water production, reducing wastewater
by up to 80%. 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. Other benefits include higher delivery pressures, faster R.O.
water production, superior water quality, and extended filter/membrane life. Our newest
Permeate Pump (ERP 500) is specifically designed for residential applications (less
than 50 GPD) where overall system noise is a key concern. The ERP 500 includes a
specially designed insert which helps the system operate in near silence, eliminating
the occasional clicking or gurgling sounds that can otherwise occur. Both the ERP1000
and the ERP500 can easily be retrofitted to upgrade existing R.O. systems.
