Also Cut Bisulfite Consumption by 30%, and End Troublesome Maintenance Burden for Instrumentation Tech and Plant Operators

The operations supervisor for Appleton, WI’s 15 MGD wastewater treatment plant (WWTP) reports that replacement of their troublesome liquid vacuum feeders for sodium hypochlorite (hypo) and bisulfite, with a next-generation liquid vacuum feeder, has ended feed outages due to plugging and leaks. He also notes a consequent 30% reduction in bisulfite needs, and the end of a troublesome maintenance burden that distracted their instrumentation technician and plant operators from their primary duties.
