C) i and iii
D) i, ii and iii
Correct Answer: A
Solution :
Recycling of wastewater after treatment reduces water pollution and help in the conservation of water. Besides reducing pollution at the source, policy initiatives must focus on removing contaminants from waste water flows, reusing water, and recovering useful by-products. The potential for reusing liquid waste can be understood by the fact that astronauts on the International Space Station drink recycled urine and use it to wash up. In Jordan and Israel, 90% and 50% of agricultural water, respectively, has been recovered for reuse.
