Peristaltic metering assists with arsenic removal in wells
Problem:
The drinking water sources in the town of Mammoth Lakes in northeast California consist of nine wells and water from Lake Mary. Arsenic is present in the well water, and the Mammoth Community Water District developed two groundwater treatment stations and one surface water station to combat it. Sodium hypochlorite and ferric chloride are used in the multistep arsenic-removal process. Initially, the well stations used solenoid type pumps, but the off-gassing nature of the sodium hypochlorite created vapor lock in the pumps.
Solution:
The district installed Proseries-M M-3 peristaltic metering pumps from Blue-White Industries to
