Decline in low-intensity rainfall reduces groundwater recharge in north India
Research carried out by IIT Gandhinagar team has found increased groundwater recharge in south India between 1996 and 2016 due to increase in high-intensity rainfall during monsoon. But in the…
Why gulping water quenches thirst
The neural mechanism that signals thirst and the thirst inhibitory neurons which signal to stop drinking have been deciphered. The research unravels how the thirst inhibitory neurons signal to stop…
IISER Kolkata’s compound makes drinking water nearly free of fluoride, metal ions
The compound synthesised by IISER Kolkata researchers can reduce copper, mercury, cadmium and iron content in drinking water to below 2 ppb, which is far below the WHO limit for…
IIT Bombay’s superior water filter needs very little power
Electrodes made of copper plates wound with cellulose thread coated with carbon nanotubes for capacitive deionisation and placed close to each other achieved 84% efficiency in ion removal. With power requirement…
IIT Hyderabad uses activated jamun powder to remove fluoride from drinking water
After two hours of contact time, the activated jamun powder was able to reduce the fluoride content of Nalgonda groundwater from 3.2 mg per litre to less than 1.5 mg…
IISc’s copper-coated membrane makes drinking water safe
The membrane with controlled release of copper ion may turn out to be a potential candidate for water purification applications with enhanced antibacterial and antifouling performances. There is an age-old…
Indian researchers use graphene sieves to turn seawater into drinking water
Producing potable water through desalination may become more efficient and less energy intensive if researchers at the University of Manchester are able to successfully use graphene oxide (GO) membranes to…
