Household water purification system comprising cartridge filtration, UVC disinfection and chlorination to treat turbid raw water
See t.ly/eIy5 — A system composed of cartridge membrane filters (25 μm, 10 μm and 1 μm opening size), UVC-lamp and chlorinator was constructed and tested with high turbidity water (up to 236 NTU). The proposed system treated around 180 L day−1 of river water and the following parameters were analysed: pressure drop in filters, turbidity, apparent colour, true colour, Escherichia coli, total coliforms (TC), UV 254nm transmittance, UV 254nm absorbance and total organic carbon in both raw and treated water. The study was conducted in three phases. In Phase 1, the raw water was rested for 24 h in a settling tank before filtration in a 10 μm cartridge filter followed by one cartridge…
