BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. [0003] Water is one of the basic requirement of a human being. But most of the water available at our homes is not fit to use as the water contains lot of impurities. So purification of water is mandatory. RO (Reverse Osmosis) systems can be used to purify drinking water. However, there are some challenges when using RO systems for water purification. Typical RO systems wastes more than 75% of water and rarely reused. Moreover, the RO system can remove essential minerals which are good for human Health. Typical RO system doesn't provides mechanism for periodic maintenance. Hard water dispensed from the RO system during purification can create scaling on surfaces and thus decrease life of appliances. Hard water lefts deposits on hairs and skin, which adversely effects on hairs, skin etc. The hard water can react with soap and detergent, so wastes more resources while cleaning and washing.
[0004] Existing solutions can include a Patent document CN203048684U which is a Reverse osmosis water treatment system. The document discloses Reverse osmosis water treatment system characterized in that comprising mixing pit that links to each other successively, settling tank, full-automatic filter, activated carbon filtration pond, clean water basin, topping-up pump, accurate filter, full-automatic ultra-filtration equipment, middle water pot, high-pressure pump, one section reverse osmosis unit, software service, intermediate water tank, two sections reverse osmosis units and pure water pond. However, the document does not discloses aspects and features related to reusing of water and

remineralizing the water using mineral filter and infuser to improve quality of water. Another reference WO2007010549A1 that discloses a household reverse osmosis based drinking water purifier where a reverse osmosis based drinking water purifier is provided for purification of water with controlled natural mineral content. Another document US6524483B1 includes a method of retrofitting an existing RO system to zero waste where diverse existing non-zero waste reverse osmosis systems are retrofittable by unskilled labor to become zero waste by a method using integrally-packaged subassemblies placed in-line in the inlet to the RO unit and in each of the outlets from the RO unit. However, the waste water from RO is not directly reusable because of hardness of water. The above mentioned documents does not disclose aspects and features related to reusing of water and remineralizing the water using mineral filter and infuser to improve quality of water and further softening of water to make it fit for household chores. [0005] Another document CN104230044A discloses a Reverse osmosis (RO) no-wastewater water purification system where a reverse osmosis is without waste water, water cleaning systems, and is characterized in that, including tap water, water inlet interface, PP filter core, cyclic water tank, topping-up pump, large hole cation exchanger resin filter core, PVDF ultra filtration membrane filter core, RO reverse osmosis membrane filter element, cocoanut active charcoal filter core, aseptic pressure pot, Living Water, water outlet mouthpiece, ultra filtration water, water outlet mouthpiece, pure water, water outlet mouthpiece. However, the document discloses aspect for softening the water.
[0006] Another document US8252171B2 discloses water purification, enhancement, and dispensing appliance with a water purifying and enhancement system of a modular construction designed as a built-in appliance located under the countertop or as a free-standing (standalone) unit. The water appliance has a water inlet for obtaining water from a supply source, scale reduction device, booster or re-pressurization pump, pre-filtration, U.V. sterilization, R.O. filtration, de-ionization (CDI or mechanical), mineral injection system (for adding desired minerals into the purified water), water diagnostic and monitoring cells, post filtration, proprietary water enhancement reactor consisting of specially

engineered and blended ores of ceramic components, and/or an electrolytic ionization chamber, and/or a magnetic chamber, a water outlet for delivery of the highly purified enhanced water product, and an outlet to grey water drain for reject water. However, the document does not discloses aspects and features related to reusing of water and remineralizing the water using mineral filter and infuser to improve quality of water.
[0007] There is a need to overcome above mentioned problems of prior art by bringing a solution that facilitates in reusing of water and remineralizing the water using mineral filter and infuser to improve quality of water. Also, the solution enables in softening of waste water to save water and make use of water for household chores.
