Verderflex Peristaltic Pumps Waste Less Water in Wastewater Treatment Plant

摘要

The City of Eagan in North Minnesota, USA required a pump capable of accurately dosing 15% sodium hypochlorite (hypo) for their new wastewater treatment plant. Hypo has outstanding disinfection properties. It is used in waste-water treatment to kill off bacteria before being discharged backrninto the environment and in water treatment as one the primary methods of drinking water disinfection. It is also a challenging product to pump. This is because hypo tends to off-gas, causing some types of pump to vapour lock. Diaphragm pumps are particularly prone to this.
