A wastewater treatment plant (WWTP) in Southern California needed to replace a diaphragm metering pump that injects ferrous chlorate into a transfer line that feeds municipal sludge to the plant’s digesters.
Its existing pump was not able to overcome the line pressure to inject the proper amount of ferrous chlorate required for the process. The new pump selected easily handles the application. Based on the success, the facility purchased a second pump to transfer ferrous chlorate from the main storage tank to the buffer tank and reports significant improvement in operations as a result.
Higher than expected line pressure creates challenges
The WWTP plant had difficulties injecting the ferrous chlorate into the transfer line because the existing diaphragm metering pump struggled to overcome the higher-than-expected line pressure of 60 pounds per square inch (psi) and higher.
The metering pump’s ability to convey ferrous chlorate into the transfer line against varying, higher ranges of pressure is important since the consistency of the sludge pumped into the digesters can vary from day to day.
