284 Increasing Drying Bed Capacity and Function
The City of Heyburn, Idaho, Wastewater Treatment plant was running out of room in their drying beds to dewater Biosolids in the winter months. Their digester was full, and they needed a cost-effective way to dewater it. Clearwater Dewatering of Nampa, Idaho, the local agent for WaterSolve LLC, worked with the City of Heyburn to solve their problem. The solids would be chemically treated and then dewatered in a Geotextile container. The project was started in September 2008.

Winter Installation and Use
Winter does not keep from effectively drying biosolids
Geotextile Tube Custom Sizes
Geotextile Tube containers can be custom sized for any existing drying bed dimension
CHEMICAL CONDITIONING
An existing drying bed location at the site allowed for a 60 foot circumference by 86 foot long Geotextile units to be installed. The city set up their own polymer injection system for treating the material as it was pumped into the Geotextile container.
GEOTEXTILE TUBE CONTAINER SIZING
Geotextile containers are manufactured from high strength polypropylene fabric and designed to allow effluent water to escape through the pores of the fabric while retaining the chemically conditioned solids. Geotextile units are available in a variety of sizes or can be custom ordered to fit most sites.
THE RESULT
WaterSolve trained the City of Heyburn Wastewater Treatment Plant personnel in the proper procedures to install and fill the Geotextile tube units. Additionally, the city was taught how to adjust the polymer dosage and to test the mixing rate as the material is sent to the Geotextile container. The City’s digester tank solids would be transferred into the Geotextile units two or three times a week. After the Geotextile bags are filled and dewatered, they are cut open and the material is hauled to a landfill for final disposal.
