The filtered water will be treated with Sodium Hydroxide. The filter backwash water will be discharged to a reclaim tank. The supernatant from the reclaimed tank will be recycled back to the plant headworks. After all backwash water from the reclaimed tank is recycled, sludge containing Arsenic, Iron, and Manganeses will be pressed into a landfill disposible filter-cake.
