GENERAL SYSTEM OVERVIEW
This manual covers three different models of our Drinking Water Systems; MPDW-90, DWS-90, DWS-PP-90. Each of these
models has four stages that the water passes through.
1
st
Stage (Sediment Prefilter) — The incoming feed water from a cold water source passes through a sediment prefilter. This
filter removes excess turbidity, sand, dust, silt, etc., that would otherwise cause the carbon filter to become prematurely
fouled.
2
nd
Stage (Carbon Block Prefilter) — After passing through the sediment filter, the water passes through the carbon block
prefilter. The activated carbon removes tastes, odors, colors, and contaminants from the water. It will also reduce the
amount of particulates, microscopic cysts, lead, volatile organic compounds (VOCs), and other contaminants.
3
rd
Stage (RO Membrane) — After passing through the two prefilters, the water then passes through the Reverse Osmosis
(RO) membrane. With a pore size of 0.0001 microns (0.00000004 inches), the RO membrane is capable of removing over
99% of TDS (Total Dissolved Solids) in the water.
After passing through the first three stages, the purified water goes to a pressurized storage tank where it is held until
the faucet is opened.
4th Stage (Post Carbon Filter) — Once the faucet is opened, the water flows from the storage tank back to the RO system
where it passes through the fourth and final stage. This carbon stage removes any tastes or odors that the purified water
might have acquired while stored in the tank. This ensures that the water from the faucet is as pure and fresh tasting as
possible when you drink it.
Optional 4
th
Stage (DWS-90 and DWS-PP-90) — Optionally, the fourth stage may be replaced with a remineralization
cartridge or a combination carbon/remineralization cartridge. The RO process removes “good” minerals such as calcium
and magnesium. This can give RO water a “flat” taste. A remineralization cartridge will add calcium and magnesium back
into the final product water. This gives the purified water a “sparkly” flavor and helps to improve the taste of coffee or
tea that is made with the RO water.
