Arsenic Removal at Canadys Power Station
Apex Engineering served as technical consultant to select a water treatment system to remove arsenic from a process waste stream of 5 mgd (3500 gpm), with ERM as the principal engineer.   Both proven and innovative technologies were evaluated to minimize capital and operating costs, while reliably treating approximately 200 ppb of arsenic to a discharge limit of 5 ppb.   Tasks included review of water quality data, bench testing results, pilot test work plans, data and reports, and existing treatment systems.
