large amounts of distilled water are needed in research labs. But the production process requires a continuous flow of water. Faced with growing water wastage in their lab, Munnalal, Sitaram and Jagat, a group of lab assistants at the Banaras Hindu University, have come up with an ingenious solution for distillation. Instead of allowing water to pass straight from the tap, through the cooling unit and back down the plug hole, as in the typical set-up, the trio used a pump, a plastic tank, some tubing and a showerhead and now save at least 750 litres a day. This becomes significant considering that use of distillation process also used extensively in industrial processes.
S C Lakhotia of the Zoology department, whose assistants came up with the idea, is excited about the technology.
