Reverse Osmosis tools have only been manufactured for the household purpose for just a few years. Earlier, it was used mainly by major corporations and the U.S. administration for purifying non-potable water supplies throughout the world. It was, and still is, used on large military and commercial ships for purifying seawater, making it appropriate for human utilization.
RO is regularly described as filtration, but it is much more composite than that. People sometimes elucidate it as a filter because it is much easier to envisage using those terms. For example, the osmosis occurrence is how our blood feeds each and every cell in our bodies. As our blood is carried into the smallest of capillaries in our bodies, nutrients essentially pass through the cells ‘wall to sustain its’ life.
A conventional filtration system, such as that in a refrigerator for example, will offer you nice tasting water, but it will not eliminate Totally Dissolved Solids, such as, SODIUM, MANGANESE, CALCIUM CARBONATE that are present in most of the municipal tap. Residential reverse osmosis systems typically incorporate a combination of conventional filtration to remove sediment and other solids, followed by activated carbon adsorption for the removal of organic compounds, chlorine, pesticides and VOC’s, prior to the reverse osmosis membrane. The end result is as close to distilled water quality as you can get, with virtually no energy consumption. The distinctive household water line pressure of 40 psi is all the energy that is essential to make the RO system work.
The chemicals that are added to the water for the period of treatment process are dependent on the class of the raw water. The part with good quality of water needs fewer chemicals than the part with bad quality of water. The common chemicals for water treatment process are as follows:
1. Alum
2. Soda
3. Chlorine
4. Fluoride
Alum is the used for the coagulation and flocculation processes. Flocculation and coagulation is the process to separate hovering solids from the water. The suspended solids will form a colloid that will become heavier and drop to the bottom of the water in this process. Alum is normally dosed as Aluminum Sulphate (Al2SO4). Sometimes, need of the quality of raw water, polymer is also supplemented as the coagulant aid. The type of commonly used polymer is polyacrylamides.
To adjust the pH balance or to increase the alkalinity of the water Soda is added. The water, in some area, is too bitter. In that case, soda is added in order to adjust the pH of the water so that it will be almost unbiased.
Chlorine is also used as a water chemical. The main purpose of using chlorine is to disinfect the water mostly from bacteria so it is safe to be drunk directly from the tap. Only after the point of choosing chlorine, the water is considered as treated water. Without the use of chlorine, the water is known as the clear water.
Fluoride is also added for the intention of dental protection which is exclusively to avoid tooth decay however; it is not applied to all water treatment plant. In some areas, extra chemicals need to be dosed to the water system depending upon the raw water quality. It is also dependent on the regulations of the countries in which the water treatment plant is positioned.
