Houston Alkaline Drinking Water

Reverse osmosis, also known as hyper-filtration, 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.

Today, we take a look at a typical home reverse osmosis alkaline system, and explain and debunk some of the terminology involved, before explaining each part’s role in the process.

Reverse Osmosis systems come equipped with a lot of parts with obscure and confusing names. We’ll start with a quick overview of a RO System and explain some of the terminology, before explaining each part’s role. A system with less would not filter the water in such a refined way.

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.

1st Stage – Pre-Sediment Filter: This is the first point of contact for the untreated water. The pre-sediment filter’s job is to remove the larger particles and protect the filters that come after it (especially the reverse osmosis membrane). It mainly removes things like sediment, rust, and sand.

2nd & 3rd Stage – Pre-Carbon Filters: The carbon filters’ (G.A.C. and C.T.O.) main function is to remove chlorine, and other organic chemicals from the water. These include chlorine, chloramine, benzene, radon, solvents trihalomethane compounds, volatile organic chemicals (VOCs) such as pesticides and herbicides and hundreds of other man-made chemicals that may come into contact with tap water as it proceeds through the system. Carbon block filters (C.T.O.) can remove some large, dangerous microorganisms, such as giardia and cryptosporidium, that can cause a number of diseases and epidemics, but nothing less than the size of the carbon itself. In addition, filters remove bad tastes and odors from the water.

Automatic Shut-off Valve: When the storage tank reaches capacity, this valve will close and stop any more water from passing through. This prevents over-spill of the water tank.

4th Stage – RO Membrane: This is where the system really earns its money, and the reverse osmosis process takes place. The membrane consists of a very fine material, which will typically only allow particles of a size smaller than 0.0005 microns (0.00000005 cm) to pass through. Viruses are too small to be removed by carbon, as they usually range between 20 and 400 nanometers in size. 20 nanometer = 0.02 microns, 400 nanometers = 0.4 microns.

Flow Restrictor: This has the job of regulating the water flow. The reverse osmosis process works best at higher water pressures, and this component helps with the systems efficiency.

Storage Tank: This is where your water is stored, prior to coming out of the faucet. Sizes range from around 3 gallons to 9 gallons.

Drain Line: This takes the by-product waste water away to the nearest drainage area.

5th Stage Alkaline Filter: This is an alkaline or pH filter, which works to add healthy essential minerals i.e. calcium, magnesium, potassium and sodium, back to the water that have been removed during the filtration process and reverse osmosis stage. It also serves to raise the pH to more alkaline levels.

This filter will increase the alkalinity without over correcting. This alkaline antioxidant filter provides abundant Active Hydrogen and also increases reduction power by increasing pH, making small water cluster and providing beneficial minerals. Negative ORP, which is produced with ionized alkaline water, severely retards the aging process. By counteracting oxidative damage to our cells. It does this by hunting down free radicals in our system and neutralizing them. Negative ORP is a very powerful anti-oxidant. and is found naturally in orange juice, glacial runoff and deep underground uncontaminated aquifer or spring water.
