Understanding, assessing, and monitoring the main indicators of water quality and their primary parameters is vital to comply with standards. Water quality parameters include a wide range of chemical, physical and biological properties, with six principal indicators: dissolved oxygen, turbidity, pH, bio indicators, nitrate chemicals, and water temperature.  Samples of water are taken to assess and monitor water quality which provides data that gives important indicators of pollution and changes in patterns of standard behaviour.  

Reverse Osmosis Systems:

These systems use the reverse osmosis technology to purify the water. In this process, the water is passed through many semi permeable membranes which layer by layer remove pollutants, bacteria and viruses, sedimentary particles. Healthy components like water, natural minerals stays dissolved for the drinkable and unadulterated water. This system should be installed by professionals only while the membranes should be replaced time to time as the impure particles accumulate of these filters decreasing its efficiency.

If you get your drinking water from a private supply such as a well, it may not be safe from microbiological, chemical, or other types of contamination. A reverse osmosis system can remove these harmful contaminants for you.

Here are some other great advantages to installing a reverse osmosis system:

• Reverse osmosis can remove dissolved solids, salts, minerals that cause hardness, organic chemicals and other impurities.
• Reverse osmosis systems can improve the taste of water for people who do not like the taste of dissolved mineral solids.
• Treated water from a reverse osmosis system will not produce scale in kettles and coffee makers.
• Reverse osmosis units may also remove contaminants such as chromium, mercury and nitrates.
• Reverse Osmosis units produce no noise other than the sound of water discharging into the drain (usually a sink or a floor drain).
• Reverse osmosis systems do not need to use salt or potassium chloride to produce soft water, so there are no added ions. This is a good solution for people concerned about additional sodium in their diet.

One should understand that like every coin has two faces, in the same way there are few cons to the process which are listed under as:

• Reverse osmosis units are usually more expensive than ion-exchange water softeners but much cheaper than distillers.
• The membranes used in the filtering process need to be replaced regularly.
• Reverse osmosis uses more water than other softening systems to operate.

Whole house reverse osmosis systems many vary from lakhs to more as it will mostly depend upon POE or point of entry.
