Dual Auger System Eliminates Clogged Pumps Caused By Flushable Wipes
7/6/2021
The Drake Pump Station, located in Saginaw, Michigan experienced chronic pump maintenance due to flushable wipes. Although the dry pit pump station represented only 0.1 million gallons per day (mgd) of flow in the city’s collection network, it required a substantial amount of servicing – up to three times a week. This consisted of two operators spending four hours manually removing rags in a confined space entry to clean out the clogged pump. It was a dirty, unplanned, and time-consuming task.

Fox Lake's Wastewater Treatment Plant Retrofit Improves Performance And Increases Capacity
2/1/2021
The existing aerated grit basin (AGB) grit removal system at Fox Lake, IL, was at the end of its useful life and needed to be replaced. There were two requirements for the replacement: they wanted to retrofit the new equipment in the existing area and to eliminate grit deposition in the grit basin which was very difficult to remove. Steve Vella, Fox Lake’s plant Supervisor, saw the HeadCell® at WEFTEC in Chicago. He liked the stacked tray concept, and thought it would be the ideal solution to their plant’s grit problem. He had seen similar operational principles in lamella systems. The stacked tray design would allow them to increase their surface area which would increase their grit system performance, while staying within the existing area used by the AGB.

HeadCell Eliminates Chandler, AZ's Punishing Grit Problem
2/1/2021
Rapid population growth created the need for a plant initially designed for 5 MGD to expand four times over two decades to treat 27 MGD today. With no grit removal the plant struggled with grit since start-up, spending hundreds of thousands of dollars on contractors to remove accumulated grit every 2-3 years. The plant wanted to eliminate their grit problems once and for all. Tired of wasting money, time, and effort on this futile but necessary task, the plant hired Wilson Engineers to evaluate various grit removal technologies to determine which type of system would be capable of eliminating their grit problem.

How The Ukiah Wastewater Treatment Plant Solved Its Debris Problem
12/22/2020
The water treatment needs of both Ukiah Valley and Lake County are served by the Ukiah Wastewater Treatment Plant. Nestled between Highway 101 on the west and the Russian River to the east, the facility features a scenic view of surrounding valleys of vineyards seemingly out of a Steinbeck novel. Construction of the facility was completed in 1958 back when the city had a population of around 9,000. Since then, the population has grown by about 78% to a total of 16,000 residents. The plant’s five pumps are equipped to handle 2.8 MGD (million gallons per day) of dry weather flow, and 20 MGD of wet weather flow. Even though the plant is equipped to remove some floating material, they were having issues with an overflow of unwanted debris.

TASKMASTER Aids In Biomass Research
12/10/2020
At CRBM Marine Biology Research Center in Quebec, Canada, researchers were in search of a grinder for a project involving marine biomass. A big part of this research project was focused on finding and extracting marine molecules that could fight against major diseases such as cancer (breast, lung, prostatic and intestinal). For the research, marine materials such as hard shells, lobster pieces, stretchable fish skin and even large and resistant seaweed needed to be ground to a homogeneous size so the research elements could be effectively extracted from the material. Getting the output size right was imperative to having a workable material for the very delicate extractions and research.
