CSIR has developed an affordable Water Disinfection System “OneerTM”. The device will go a long way in meeting the requirements of potable water in rural and urban areas.
Water pollution is the contamination of water bodies, usually as
a result of human activities. Water bodies include for example lakes,
rivers, oceans, aquifers and groundwater. Water pollution results when
contaminants are introduced into the natural environment.
The most important water
contaminants created by human activities are microbial pathogens, nutrients,
oxygen-consuming materials, heavy metals and persistent organic matter, as well
as suspended sediments, nutrients, pesticides and oxygen-consuming substances,
much of it from non-point sources. Heat, which raises the
temperature of the receiving water, can also be a pollutant. Pollutants are
typically the cause of major water quality degradation around the world.
Globally, the most prevalent
water quality problem is eutrophication, a result of high-nutrient loads (mainly phosphorus and
nitrogen), which substantially impairs beneficial uses of water.
Projected food production
needs and increasing wastewater effluents associated with an increasing
population over the next three decades suggest a 10%-15% increase in the river
input of nitrogen loads into coastal ecosystems, continuing the trend observed
during 1970-95.
More than 80% of sewage in
developing countries is discharged untreated, polluting rivers, lakes and
coastal areas.
Many industries – some of
them known to be heavily polluting (such as leather and chemicals) – are moving
from high-income countries to emerging market economies.
Despite improvements in some
regions, water pollution is on the rise globally
About “OneerTM”
It
is useful for continuous treatment of water and eliminates all disease causing
pathogens such as virus, bacteria, fungi, protozoa and cyst to provide safe
drinking water to domestic and communities settings as per National and
International standards prescribed for potable water (BIS, WHO etc.).
Importance
According
to the World Health Organization, “access to safe drinking-water is
essential to health, a basic human right and a component of effective policy
for health protection”.
However,
currently, a large proportion of India’s rural community has been consuming
water that does not meet the WHO drinking water quality standards. And
infection through drinking water results in an increase in morbidity and
mortality particularly amongst children.
Oneer
developed by CSIR-IITR, will provide access to safe and clean drinking water at
a cost of just 2 Paise / Ltr. The Community level model is of 450 LPH
capacities which can be scaled up to 5000 to 1 lakh L/day; and is also
maintenance and membrane free. The technology will be helpful especially for
rural people since it can be solar powered.
