Operation Overview
A pressurized water source is fed to the first pre-filter which is a 5 micron spun poly sediment
filter. The water then passes through the sediment filter to the carbon block filters. Water
passes through the carbon block filters and then on to the membrane filters. Product water
(permeate) from the membrane filters is conveyed to the automatic shutoff valve (ASO).
Product water from the “Out” port on the ASO can then be attached to a tank or point of use.
Waste water (concentrate) from the membrane is conveyed to the flow restrictor. The water
leaving the flow restrictor is conveyed to an onsite drain.
