Process Description:
Coagulated and flocculated raw water passes through ultrafiltration units for turbidity, suspended solids, giardia and virus removal. The filtered water further undergoes disinfection process by UV and post chlorination systems before storage and distribution.

Specified Effluent Quality:
Parameter Unit Expected Warranty
TSS mg/L ≤3.0 ≤3.0
Turbidity NTU <0.1 <0.1
Giardia Log ≥4.0 ≥4
Cryptosporidium Log ≥4.0 ≥4
Viruses (UF only) Log ≥1.5 ≥1.5
Viruses (UF + UV) Log ≥4 ≥4
