6 STAGE ALKALINE REVERSE OSMOSIS CORE SYSTEM. Reverse Osmosis product water is more acidic due to it's purity. By the time the water is processed through the various stages, after the reverse osmosis stage, minerals etc has been removed.To replenish necessary minerals, an alkaline filter is recommended. 4th stage of this system is an alkaline filter, which replaces calcium, magnesium, sodium potassium ion etc, taken away during the purification process. The 5th stage is an inline carbon filter that polishes the water for a sparkling taste. Reverse osmosis, also known as hyperfiltration, is the finest filtration available today. It is the most common treatment technology used by premium bottled water companies.
It is effective in eliminating or substantially reducing a very wide array of contaminants, and of all technologies used to treat drinking water in residential applications, it has the greatest range of contaminant removal. Reverse osmosis will allow the removal of particles as small as individual ions.
Reverse osmosis uses a membrane that is semi-permeable, allowing pure water to pass through it, while rejecting the contaminants that are too large to pass through the tiny pores in the membrane. Quality reverse osmosis systems use a process known as crossflow to allow the membrane to continually clean itself.
As some of the fluid passes through the membrane the rest continues downstream, sweeping the rejected contaminants away from the membrane and down the drain. The process of reverse osmosis requires a driving force to push the fluid through the membrane (the pressure provided by a standard residential water system is sufficient - 40 psi+). Since membranes are subject to degrading by chlorine, iron, manganese, and hydrogen sulfide, and to bacterial attack, a sediment pre-filter and an activated carbon pre-filter and/or post-filter is included with your reverse osmosis system. RO systems are generally the best choice for water contaminated with high nitrite levels as might be found in agricultural areas.
This unit contains the following. 1 SEDIMENT FILTER 1 GRANULAR CARBON FILTER. 1 INLINE POST CARBON FILTER 1 INLINE ALKALINE FILTER CLEAR HOUSING.
1 CLEAR FILTER HOUSING 2 WHITE HOUSINGS. 1 AUTOMATIC SHUT OFF VALVE. 1 FEED WATER SADDLE VALVE.
1 CHECK VALVE ON MEMBRANE HOUSING. 1st Stage - All of our sediment filters use multi-gradient spun polypropylene filter cartridges. These cartridges use the entire depth of their media by trapping the largest sediment particles on the outside of the filter, then gradually stepping down the size of particles they will reject as the water moves closer to the core of the filter. The result is longer filter life, greater dirt-holding capacity, higher flow rates, and remarkably low pressure drop. The 100% pure polypropylene media is highly resistant to bacteria and chemicals, making this an excellent choice for both well water and municipal water treatment applications.2nd Stage - Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. Activated carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the of the contaminants are drawn to the surface of the carbon granules. Stage - With carbon block filters, water is forced through the pores of the densely compacted carbon block, where a combination of mechanical filtration, electrokinetic adsorption, and physical/ chemical adsorption take place to reduce a wide range of contaminants. Solid Carbon Block technology can reduce chlorine, taste and odor problems, particulate matter, and a wide range of contaminants of health concern -- cysts (cryptosporidium and giardia), VOCs (pesticides, herbicides, and chemicals), certain endocrine disrupters, Trihalomethanes (cancer-causing disinfection by-products), heavy metals (lead, mercury), turbidity, MTBE, Chloramines and asbestos. Solid carbon block filters do not remove healthful, naturally-occurring minerals.

Inline Alkaline Calcite/Corosec filter : Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium.
It does not overcorrect under normal conditions. Reverse Osmosis product water is acidic due to it's purity. To buffer the water back to a more natural balance, we highly recommend this filter for drinking water. The composition of this food grade media will also add minerals to the water that is stripped out by the reverse osmosis membrane.
Post Carbon Filter - A final Polishing step that ensues a sparkling clean and pure water taste. The feed water valve can be either the saddle valve or the feed water adapter depending on the model.
