2 REVERSE OSMOSIS INSTALLATION AND USER GUIDE BARRIE ● ONTARIO ● CANADA 705.733.8900 WWW.EXCALIBURWATER.COM 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 Block The Reverse Osmosis Carbon Block Pre-filter 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. Ceramic Filter (EWR 7100P model Only) This filter removes the bacteria, cysts and particles. This filter also prevents the microbiological growth within the ceramic element. 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 5100E & EWR 7100P models only) The Reverse Osmosis Enalka filter includes an ultra-clean white granular media. Enalka filter of Reverse Osmosis system is used 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.
