Case Study: Killingly WWTP – Danielson, CT

Reduces annual energy costs and improves process control of the wastewater treatment for better nitrogen removal Killingly WWTP replaced its multi-stage centrifugal and positive displacement blowers with APG-Neuros turbo blowers. The high efficiency blowers and improvements in the aeration control and modifications in the SCADA for improved DO control reduce the plant’s annual energy costs.…

Case Study: Haliotis Wastewater Treatment Complex, Nice France

The APG-Neuros Turbo Blower saves energy consumption and leads to modernization of the Haliotis Wastewater Treatment Complex in Nice, France Project Background The Haliotis Wastewater Treatment Complex was designed, built and operated by Degrémont since 1988, with its main objective to treat wastewater. Although composed of a primary treatment followed by settling, the majority of…

Case Study: City of Watsonville, CA WWTP

APG-Neuros’ Turbo Blower reduces energy consumption, while improving the working environment The City of Watsonville replaced one of its centrifugal blowers with a new APG-Neuros NX Series turbo blower combined with replacing its coarse-bubble diffusers with more efficient fine bubble aeration diffusers. The new turbo blower supplies the majority of aeration, while the three remaining…

Case Study: City of Orange Cove WWTP, California

Retrofit upgrade project confirms energy savings at wastewater treatment plant The city of Orange Cove is an agricultural community in Fresno County that is located along the eastern foothills of the Sierra Nevada Mountains. Through value engineering and the assistance of incentive money from their utility provider, the WWTP pursued various upgrades; including the addition…

Case Study: King County WTD – South Treatment Plant

Decrease energy consumption, noise level, heat generation, and maintenance costs Project Background Increasing energy efficiency is a top priority at King County, so it wasn’t difficult to find an opportunity when it came to their existing multistage centrifugal (MSC) blowers at their South Plant facility. With the support of Puget Sound Energy and the Washington…

Case Study: City of Gig Harbor – Gig Harbor Wastewater Treatment Plant

High energy and maintenance costs, inflexible operating range and high noise levels Gig Harbor WWTP replaced its positive displacement blowers with APG-Neuros turbo blowers, reducing its energy consumption, increasing its operational flexibility, creating a pleasant working environment and saving thousands of dollars thanks to its small foot print. The aeration blowers were one of the…

Case Study: LOTT Alliance – Budd Inlet Treatment Plant – Aeration Blower Retrofit – Dual Core

High energy consumption and limited and inefficient operation LOTT Alliance secured a Puget Sound Energy (PSE) grant to replace its existing Positive Displacement blowers with Dual Core High Efficiency APG-Neuros turbo blowers which resulted in 100 HP power reductions and savings of around 300 HP based on the plant’s average operation. Challenge The LOTT Alliance,…

Case Study: City of Vancouver, WA – Westside Water Reclamation Facility

Multistage blowers unable to meet required flow turndown Challenge The City of Vancouver treats approximately 25 million gallons of wastewater each day between its two wastewater treatment plants. The aeration systems are required to provide oxygen for the biological processes and mixing to keep solids suspended for more effective treatment. In 2011, the Westside Water…

Case Study: Lakota WWTP, Lakehaven Utility District, WA

High energy consumption and limited and inefficient operation NAPA Sanitation District’s consultant QuEST and Herwitt Engineering conducted a study on replacing the plant’s Multistage Centrifugal blowers to address their inefficient operation, operational inflexibility and high energy consumption. Following the recommendation of the study, NAPA Sanitation District replaced their existing blowers with the High Efficiency turbo…
