How To Filter Rainwater?
Rain water is the purest form of water, when it is still suspended in the air; purer than the tap water.
But once it falls on the rooftop or the garden or any other rain water collecting surface, it is exposed to all the good and bad elements of nature.
It is not suitable to use rainwater for drinking in this non potable form, and hence it has to be treated and filtered, to make it safe for drinking.
When not in use, the storage tank gathers lot of dirt and sludge.
This can be removed by the use of first flush diverter device, through which the first lot of collected rainwater is used to flush out and clean the storage tank.
The collected rain water in the storage tank is oxygenated at first, filtered with a wire mesh and other filters like the activated carbon block filters, granulated carbon filters, ultraviolet rays or reverse osmosis processes.
After water treatment, the rain water is fit for drinking.
This process of collecting the rain water and then using it for various purposes is known as rainwater harvesting.
