Reverse Osmosis System

Reverse Osmosis System Household RO Water Filtration Unit Introduction The household RO water filtration unit is a miniaturized water filtration station. It is simple to connect water dispenser with drinking water pipeline directly, connect the tee-joint outlet of water dispenser with pressure tank, and connect rear active carbon with drinking water gooseneck tap. It consists of automatic water feeding system, 5μm PPF melt blowing PP fine filter element, CTO active carbon adsorbent filter and 5μm PPF fine filter + UDF coco shell particle active carbon adsorbent rear filter. The household RO water filtration unit is able to detect running water pressure and make judgment if there is water at the inlet. The water pump is protected as it runs only with water.

Features of RO Filtration System No additive is used or chemical reaction is occurred during treatment and the water is drinkable directly. Automatically make filtered water uninterruptedly with a constant water quality to avoid the risk of secondary contamination. Self-regulate water making system in accordance with demand and energy is saved. Simple maintenance, safe and reliable with low trouble.

Replacement of Filter Element Type Filter Element Replacement Cycle PPF precipitation element 1st filter element 3 - 6 months CTO extruded active carbon 2nd filter element 6 - 12 months UDF particle active carbon 3rd filter element 6 - 12 months RO reverse osmosis membrane 4th filter element 12 - 24 months T33 rear active carbon 5th filter element 12 - 24 months The replacement cycle is for reference only as the service life of filter element is dependent on the raw water quality.

Function of Five Stages Filter Element

(SED; 5 Micron Sedimentary Filter)
Sediment Removal / PP– Commercial grade sediment filter. Sediment filtration extracts suspended sediment, dirt, rust, silt and sand ranging from filtration of 20 microns down to 5 microns. Reduces particles 8 times smaller than what the naked eye can see. (GAC; 5 Micron Granular Activated Carbon for Chemicals)
Granulated Activated Carbon /UDF – High efficiency pre-filter reduces and removes: chlorine, volatile organic compounds (V.O.C), pesticides, nitrates, herbicides, tastes, odor, and disinfection by products (Chloramines, THM, TCE). Cartridges are constructed totally of FDA grade materials and media. (CCB; 1 Micron Coconut Carbon Block for Chemicals)
Carbon Block Filter / CTO – High efficiency pre-filter removes Chlorine, then reduces or entirely removes Pesticides, Nitrates, Herbicides, tastes, odor, and disinfection by-products (chloramines, THM, TCE), Volatile Organic Compounds (V.O.C). ( Reverse Osmosis Membrane)
Reverse Osmosis Membrane- This semi permeable membrane filters and rejects tiny impurities down to 1/10,000th of a micron removing at least 95% of all impurities such as colloid, heavy metal, dissolved solids, germs and other harmful substances. Virtually only water molecules and dissolved oxygen can pass through the Reverse Osmosis Membrane. The rejected contaminants are flushed to drain. The product water is the extremely pure, crisp healthy drinking water. (PC; Post Carbon Final polishing filter for taste and odor)
Post Activated Carbon Filter / T33- This carbon filter does an excellent job of "polishing" any dissolved solids that although unlikely, may have slipped through the 95% removal rate of the Reverse Osmosis Membrane and also through the DI Resin Bead Stage to give added assurance that you are getting the highest quality drinking water possible. The Final Polishing Filter also adds the mineral charcoal back into your water which helps to give the water a full bodied taste and also helps your body to detoxify.
