Dear IAN,
For such big capacity, the best solution could be 1) Conventional Coagulation with coagulant dosed at higher concentration than normal (say 2x, 3x), then As can be removed 2) If budget allows, put a preO3 upstream. In combination with high dosage of coagulant, As can be effectively removed 3) You can perform the jar tests to confirm the coagulant type (alum or FeCl3) and the concentration.

Many thanks, great responses. There are questions about the flow rate mentioned so I'm checking with my client. Have a feeling it should have been 'per minute'. I've also forwarded all responses to them. I'm very appreciative.
