Here are the following steps in which Municipal Water Treatment occurs:

·        Activated carbon treatment:

The water is passed through the porous activated carbon sheets. This method is used to remove the maximum chemicals from the water. These chemicals react with the activated carbon making the water purified. This is one of the easiest way of removing the impurities from the water.

·        Demineralization:

Demineralization is the process in which all the minerals from the water are removed making it plain and simple. Demineralized Water otherwise called Deionized Water, Water that has had its mineral particles evacuated. Mineral particles, for example, cat ions of sodium, calcium, copper, and so forth and anions, for example, chloride, nitrates, and so forth are regular particles introduce in Water. Since the dominant part of Water pollutions are broken up salts, deionization delivers a high immaculateness Water that is for the most part like refined Water, and this procedure is fast and without scale development. De-mineralization innovation is the demonstrated procedure for treatment of Water. A DM Water System produces mineral free Water by working on the standards of particle trade, Degasification, and cleaning. Demineralized Water System finds wide application in the field of steam, power, process, and cooling.

·        Pretreatment:

After the process of purification, the minerals are again added to the water. Remineralized Water will be water that has had some mineral substance added back to it. The invert osmosis process is non-particular – it evacuates the ‘great’ stuff like calcium, and magnesium, alongside the ‘terrible’ stuff like pesticides, overwhelming metals, and pharmaceuticals. The procedure of remineralizing the water includes back a portion of the well done. This is normally finished with a post-channel that contains some type of calcium or magnesium. The most widely recognized substances utilized are Calcite (calcium carbonate) and Corosex (a magnesium compound). A few channels utilize a blend of both. The switch osmosis treated water is gone through one of these channels where it breaks down a portion of the filtration media promptly before being administered. Calcite remineralizers will convey the pH to impartial (around 7.0) while Corosex will bring the pH over 7.

·        Chlorine treatment:

Chlorination may likewise be done as the last advance in the treatment procedure, which is the point at which it is typically done in most treatment plants. The fundamental target of this chlorine expansion is to purify the water and keep up chlorine residuals that will stay in the water as it goes through the conveyance framework. With a specific end goal to battle water diseases, diverse sanitization strategies are utilized to inactivate pathogens. Alongside other water treatment procedures, for example, coagulation, sedimentation, and filtration, chlorination makes water that is ok for open utilization.

Chlorination is one of numerous strategies that can be utilized to sterilize water. This technique was first utilized over a century back, is as yet utilized today. It is a concoction sanitization strategy that utilizations different kinds of chlorine or chlorine-containing substances for the oxidation and sterilization of what will be the consumable water source.
