Rotary impingement device quickly dislodges grease from lift station

Problem: Ryland Holmes of Virginia Public Works Equipment, a municipal, high-tech and heavy-equipment-needs company, was looking for a better way to clean lift stations. Customers were struggling with grease problems and needed an effective way to resolve their issues without demanding more of their manpower or budget.

Solution: Gamajet, part of the Alfa Laval Group, provided the company with an EZ-8 automated rotary impingement device, configured for 80 gpm and 300 psi. Members of the City of Virginia Beach Department of Utilities and other local municipalities and sewer authorities watched a demonstration as the device, which was used with the department’s jetter truck, scoured the wet well clean in 12 minutes. Another half-cycle was run to further decimate the grease pad, which could then be suctioned into a combo truck or washed downstream.

Result: The lift stations were free of grease in 12 minutes without laborers entering the lift station, eliminating the hazardous, time-consuming confined-space-entry riggings. The city decided to purchase one of the units, and authorities are able to stay ahead of their lift station problems, provide better service to their constituents, increase safety and reduce demand on their resources. 877/426-2538; www.gamajet.com.
