For the past 10 to 15 years, wastewater treatment operators have faced increased clogging issues related to baby wipes, disposable diapers, rags, and other foreign debris. At the same time, the use of low-flow toilets has increased the solids concentration of sewage flow. This discussion with Brad Jernigan and Christina Foster from Pentair addresses differences between how grinder pumps (low flow/high head) and chopper pumps (higher flow/lower...  Continue Reading..

Population growth, stricter regulations, and increased energy costs continue to exert significant pressure on municipal wastewater operations. But rather than investing in tired, old solutions such as the construction of additional concrete tanks, water system managers are seeking new ways to stretch the limits of their infrastructure.  Continue Reading..

Clogging continues to be the biggest headache at municipal wastewater treatment operations, while rising energy costs and stricter government controls have been emerging as larger issues. The transportation of waste, however, is a rapidly growing concern as a higher solids content is being driven by cutbacks in water consumption. The increase in fibrous materials is challenging for both the pump hydraulics and the pipe works. In this Water Talk...  Continue Reading..

With electric motors playing such key roles in water and wastewater treatment and water distribution operations, protecting those motors is fundamental to keeping processes flowing smoothly.
