NSI develops gadget to help sugar mills save water
To address the problem, National Sugar Institute (NSI) has developed a purification unit for treatment of waste water from sugar industry. According to recent guidelines of Central Pollution Control Board (CPCB) for sugar industries, not more than 200 litres of waste water per tonne of cane crushed should be discharged from an individual sugar mill. However, a purification unit developed by NSI scientists can bring down the water usage to 160 litres per tonne of cane crushed.
