Household Water Purification System
The quality of drinking water is essentially of primary importance to human health. The potable water intended for human consumption should be aesthetically attractive and free from chemical substances and micro-organism in amounts which would prevent a health hazard. Natural water generally contains some dissolved/ suspended constituents which impart colour, odour and taste to water. Clear water from well, pond, streams and other sources may not be necessarily being free from harmful dissolved ions and micro-organisms.
In practice, it is necessary to evolve an eco-friendly technology that will be suitable for removal of major hazardous substances from water including heavy metals like iron, arsenic, manganese, etc. Low cost, reliable and affordable technologies for removal of contaminants from water sources for home scale use are the urgent requirements that will benefit the mass population. Taking this view into consideration, a household water purification unit was developed to provide pure drinking water by removing most of the harmful contaminants present in water. It enables to remove four main contaminants viz. arsenic, iron, manganese and bacteria (More works are under progress) from drinking water but retaining other essential dissolved salt/ions in water within the acceptable value.
