Creating efficiencies with water sampler system
Problem: A water recovery facility in Michigan monitors the quality of the entire plant from seven sample points. The samplers were more than 20 years old and discontinued by the manufacturer, so parts and services were no longer available. The samplers constantly clogged and overflowed, and keeping them clean was difficult. Mechanical and electronic parts had to be switched between units, and the process became unsustainable.
Solution: A fully automatic water sampler from Endress+Hauser provided a retrofit solution. Liquistation CSF34 samplers automatically take water samples for analysis. They include menu-guided sample programming and tool-free maintenance.
Result: Since the samplers were installed, the plant has seen improved air quality in the sampling room, and the samplers enable the team to accurately monitor all permit-monitored and nonpermit points. 888-363-7377; www.us.endress.com
Liquid-only, low horsepower pump systems replace grinders
Problem: Trash was clogging pumps daily in the sewer system in Palestine, Texas. Items including wipes, plastics, clothing, rags and trash bags caused the clogs and led to catastrophic downtime. The items clustered to form rag balls. The system included three return activated sludge pumps that required manual clean-out 21 times a week, costing $3,000 weekly. The process was time-consuming and dangerous, as team members had to shut down the pumps, pull them up and manually dislodge blockages from the sharp impellers.
Solution: The city installed three DERAGGER systems from Industrial Flow Solutions to monitor the pumps’ amperage, voltage and hertz outputs and sense potential overloads. If a clog is detected the pump impellers reverse direction, eliminating the clog or rag. The technology is available in four models, providing intelligent data monitoring and analytics to meet specific application needs.
Result: Eight months post-installation, there were no shutdowns, and the city saved over $100,000. 860-631-3618; www.flowsolutions.com
