STORAGE BY CONVERTING IT TO DRINKABLE WATER FILED OF THE INVENTION

The present disclosure relates to an IoT based method and system for rainwater harvesting and storage by converting it to drinkable water.

BACKGROUND OF THE INVENTION

Shortage of drinking water is one of most well knows challenge in the world. According to a world economic forum 2016, water crisis will be a global risk for next 10 years. The shortage of drinking water is reduces with the help of harvesting the rain water, in those areas where rain falls is adequate, and converting the stored rain water into drinkable water. It has been seen that in economically weak countries, people are facing problem of drinking water especially in the summer season.

One of the major water crisis management tool is to store the rain water by building the capacity to do it and covert that stored rain water into drinkable water. The quality of the water is determined by assessing three classed of attributes which are physical, chemical and biological. The physical standards of water quality are such as color, odor, turbidity, and conductivity. The chemical standards are such as pH, Acidity, Alkalinity, Hardness, Solids Harmful Chemicals, Chlorides, Sulphates, Iron, Nitrates, Heavy Metals, and Pesticides.

In one prior art solution (JP2005313134), the invention provides a rain water cleaning method for utilizing the rain water as drinking water and as a source of water for many other daily life work. The method comprises: passing the rain water through a filtration column which consists crushed granite, then passing the water through an air blow tank, thereafter passing the water through a column retaining a highly electrical conductive bamboo charcoal block piece twice and then passing the water through a primary activation treatment tank retaining the highly electrical conductive bamboo charcoal block piece treated by the raw water of pie water and activated ceramic, thereby changing the rain water into water suitable as the drinking water.

In another prior art solution (JP2011121003), the invention provides a system for utilizing the rain water. The system includes: treating the collected rain water to the level that the treated rain water satisfies standards for recycled wastewater; treating a part of the treated rain water by the reverse osmosis membrane; supplying a liquid permeated through the reverse osmosis membrane as drinking water; and returning the condensate, which is not permeated through the reverse osmosis membrane, to a miscellaneous water line.

Figure 3 illustrates the flow chart of the proposed disclosure in accordance with an embodiment of the present disclosure. The IoT based water purification of the harvested rain water mainly aims to provide cleaner and consumable water for almost every household. The method of the purification can be divided into two processes. The rain water is harvested from the roof top and stored in a tank placed preferably on the roof top, the tank allow the flow of the water directly to a thin glass tank with the help of gravity. The water collected in the glass tank will be covered by a slanted glass layer by a certain angle. When the sunlight fall on the thin glass tank and passes through the slanted glass layer to the accumulated water, the sunlight kills most of the harmful bacteria and microbes by increasing the temperature of the water. The water inside the thin glass tank will evaporate due to increase in temperature and because of that the water droplets will residue on the inner surface of slanted glass layer. The droplets will be collected through a tube placed just beneath the thin slanted glass layer which lead that evaporated water to a IoT sensored fitted outlet valve, then this collected water will pass through a temperature sensor with digital display. This process is the first step for purification which kills around 60% of the harmful bacteria and any other microbes. The second step of the purification is removing the remaining harmful organisms and chemicals, by collecting the evaporated water in a secondary vessel by allowing the water to pass through a ceramic vessel. The pores of the ceramic vessel traps the impurities as the water passes through them making it efficient for drinkable as well as many other purposes. The ceramic pot removes the bacteria, sediments and turbidity in the water.

Figure 4 illustrates the line diagram of the temperature controlled solenoid valve with display using adruino R3 in accordance with an embodiment of the present disclosure. The figure includes the images of a temperature sensor, a solenoid valve working diagram, a Arduino and a digital display. The temperature sensor is used with the digital display and checks whether the contained where the evaporated water droplet is stored maintains an adequate temperature or not and if the container doesn't have an adequate temperature, then the temperature is adjusted by the temperature controlled solenoid valve. A temperature controlled solenoid valve is used with a display using Arduino Uno R3 which allows the measure of temperature adequately.
