Mobile War Against Water-Borne DiseasesBy Unregistered Visitors, Section Health
Close to half a million children die in India every year of water-borne diseases such as diarrhoea, enteric fever, typhoid and hepatitis. Public health officials are convinced that hundreds of thousands of lives can be saved by the seemingly simple act of ensuring access to clean, potable water. But somehow, that's been easier said than done.
That could change. In a significant development in the war against such infections, a new `mobile' or `personal' water purifier that costs very little has been developed. Named Handypure in its present, prototype stage, it is said to be the first in a new class of electrically operated, flow-based water purifiers. The purifier has been developed at the All India Institute of Medical Sciences (AIIMS) and is now at IIT Delhi for evaluation, characterisation and possible improvement. It is a compact purifier, operating on self contained batteries, small enough to be carried in a ladies handbag. It can be used anywhere, weighs about 700 gms (with batteries) and costs approximately Rs 600 without batteries and mobile charger.
It can also be mounted on a fixed stand (see pic) and fed with water from a container for use indoors or `offline'. This may be of relevance for more than 50% urban homes that either lack piped water, or where connecting commercial purifiers to the plumbing may not be possible.
The purifier can also be operated from external batteries, mains (through adapters) or from solar panels. The purifier can use feedwater from all municipal sources or ground water uncontaminated by chemical toxins. On the anvil is a proposal to make the purifier available as a `kit' (without UV lamps) for less than Rs 200 to facilitate its access by lowincome households. Source-(TOI, 12/4/07)
