INTRODUCTION
Your new Reverse Osmosis Drinking Water System uses a combination of filtration technologies to
reduce unwanted contaminants in your water supply. Your Reverse Osmosis System uses the 5 filtration
stages which combines to give you the best in clear sparkling Reverse Osmosis water.
FILTRATION STAGES
Mechanical Filtration
The Reverse Osmosis Turbidity Pre-filter will remove suspended matter that are larger than 5-micron as
well as silt, dirt, scale and rust. The 5-Micron nominal rating helps give maximum life to the Reverse
Osmosis Membranes.
Carbon Blocks
The Reverse Osmosis Carbon Block Pre-filters contains carbon with a vast network of pores. The
tremendous surface area of these pores (typically 800-1200 square meters per gram of carbon) gives the
Reverse Osmosis carbon very good adsorption sites for substances that contribute to tastes and odors.
The Reverse Osmosis carbon block in the Pre-filters will remove chlorine that may be present in the feed
water. This Reverse Osmosis pretreatment is necessary for membrane protection.
Reverse Osmosis Membrane
The Reverse Osmosis Membrane is the heart of Reverse Osmosis filtration system. The Reverse Osmosis
system is designed to reduce the dissolved mineral content of the water. Minerals picked up in the
environment by the water are measured as Total Dissolved Solids (TDS). In the Reverse Osmosis process,
dissolved minerals are separated from the incoming water (feed water). The Reverse Osmosis excess
minerals are rinsed to drain (the Reject Water) and clean water (permeate water) is stored in tank.
Enalka Filter (EWR 5075E Model Only)
The Reverse Osmosis Enalka filter includes an ultra-clean white granular media. Enalka filter is the last
stage of Reverse Osmosis system to neutralize the pH of water.
In-Line Activated Carbon-Coconut Shell Post Filter
The Reverse Osmosis In-Line Activated Carbon Post Filter is located after the Holding Tank and reduces
tastes and odors that may pass through the Reverse Osmosis system. It adds a final polish to the water.
REVERSE OSMOSIS COMPONENTS
Automatic Reverse Osmosis Shut Off Valve (ASO)
The Reverse Osmosis ASO Valve senses when the product water tank is full and closes the feed water
supply to prevent excess Reverse Osmosis reject water going to drain when the Reverse Osmosis System
is not producing water.
