New method to purify water

Water being the basic necessity of life needs to be easily available to us in its purest form. Unfortunately, in today’s day and age, neither is water easily available, nor is it inexpensive and pure. However, this did not refrain the Barlett doctoral candidate, Shneel Malik from producing a technique using ceramic tiles and algae which purifies water without any harmful chemicals or extra cost, which is called Indus.
The key ingredient in making this purifying wall is the numerous small channels carved inside the ceramic tiles. These channels, laden with algae hydrogel, plucks out all the toxins once the water passes through it. The water may pass through this channel more than once if felt necessary.

The ultimate aim for developing this technique was to make the process of water purification for textile industry easier and cheaper. In an interview, Malik has said that she’s been observing the work of small scale jewelry workers in some parts of India. She has noticed that they leave out highly dangerous chemical waste into the environment. “This gesture is purely an effort to save the environment”, says Malik.

Malik’s battle for wastewater treatment continues to grow, even though there are challenges on the way. One of those challenges is the need to replace the hydrogel in the ceramic tiles after every few months. However, this truly is a commendable effort on the part of Malik.
