Reverse osmosis (RO) is one of the efficient techniques used to purify water. It is a special type of filtration which uses semi-permeable thin membrane with pores fitted on both the sides to let go off the clean water by segregating wastes and dirt in the membrane itself. The reason behind using Reverse osmosis system is to get an access to high quality clean and safe drinking water. a thin membrane is attached at both the ends which is extremely delicate and highly protective against the toxic ions and gases dissolved in impure water. Widely used at commercial and household level, this technology is not free of disadvantages. Variety of companies have undertaken the task of manufacturing Reverse osmosis system by installing updated and advanced features which lack safety and lead to damage with minimum benefit. Based on various clinical testing and Ph tests, 4 gallons of water gets wasted for cleaning just a gallon of water. If a person uses 3 gallons of water for productive purposes in a day, she/he wastes 12 more gallons of water, which is a whopping amount of waste. This piece of information is enough to establish a fact that only 25% of water is cleaned rest 75% of the natural resource gets drained out.
In producing high quality of drinking water, the essential minerals and rich vitamins are sacrificed hence making the water quality deficient of necessary minerals, vitamins and supplements when compared to house water filtration systems. In addition, Reverse osmosis takes approximately 3-4 hours to filter just one gallon of water, which means that it would take a whole day to filter all the water for every household hence the process is time consuming. With all the new technologies installed, the process might take less time to filter water but increases water wastage.
