Drinking Water Disinfection System-OneerTM



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.




The Problem – Water Pollution- Global Scenario

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.
