Well done Aamir. To add a little, whether to use UV, UF, or RO depends more on the quality of the raw water source and your budget. So conduct water quality test to know the quality of water in the area of your project. UV is highly needed to treat surface water because the microbiological contamination is likely to be high. RO is necessary if the raw water source is salty and has above average metal contamination. However, if the raw water source is of good quality, UF is economically good to produce standard drinking water.
