My daughter - getting into 8th std at Prakriya, Bangalore - is working on a project that entails treating and using the water discharged from a washing machine.
She wants to explore if the water - instead of being left as waste into the drains - can be treated and reused for domestic applications like gardening, washing, etc. The key problem that she needs to solve is to separate the detergent /dirt from water.
Can you give us your suggestions or direct us or to anyone who can provide her with inputs on this?
