Turbo blower leads to energy efficiencyProblem
Lakota Wastewater Treatment Plant in Lakehaven Utility District, Wash., sought to address rising energy costs and aging equipment. The 17-year-old 250 and 350 hp positive displacement blowers used for secondary treatment were noisy and inefficient and did not provide operational flexibility. Because the 250 hp blower could not meet low-flow aeration requirements, plant operators had to turn on the 350 hp blower, increasing power consumption.Solution
In 2008, the plant replaced the 250 hp blower with an NX300 300 hp high-speed turbo blower from APG-Neuros. The project was eligible for an Energy Grant from Puget Sound Energy
