Biosolids can be safely disposed of or used beneficially for downstream processes, including soil nutrition and energy. Wastewater treatment plants face significant biosolid storage challenges before disposal or usage. Plant operators often cite pathogen and odor control as vital issues, but storage systems are challenging. How do you fit an essentially limitless material supply into a specific space?

JMS offers a breadth of storage, leveling, and discharge systems tailored to various unique applications. As part of our comprehensive system solutions, the JMS Bio-HOPPER represents a versatile and cost-effective solution for biosolid storage. 

Each Bio-HOPPER consists of a rectangular or square storage vessel designed explicitly to our customer’s specifications. Every component, from the quantity and size of inlets to the structural reinforcements, is carefully designed to perform for specific applications.

Success Story

The Woodins settled on the banks of the Sammamish River in Washington, the first family in a community developed in 1888. Today, Woodinville, WA, home to over 10,000 residents, is part of King County’s regional wastewater treatment system. The Brightwater Treatment plant, north of Woodinville on State Route 9, is one of four that treat the area’s wastewater.

King County has safely recycled biosolids for over twenty-five years. When the Brightwater Treatment Plant was started in 2005, the plans included equipment for biosolids, thickening, digestion, and dewatering before removal for beneficial use off-site.

JMS designed and manufactured a biosolids Bio-HANDLING truck load-out station for this location. Two extra large JMS Bio-HOPPERs (Enclosed Storage) work with JMS Bio-SCREW (Screw Conveyor) and Bio-GATE (Slide Gate) as the system backbone. Due to facility loading restrictions, we designed special pneumatic gates for fully automatic capabilities. Plant personnel, including Operations Supervisor Andy Strehler, have enjoyed working with JMS and are enthusiastic about continued system optimization.
