General Description
KWS addressed a customer need to store and transport residuals from the Headworks process area of a municipal wastewater facility. The residuals from this part of the plant are dewatered screenings and grit which are very odorous and may pose a health risk to operations staff. Furthermore, the area is deemed high risk of explosion and equipment must be designated explosion proof (i.e. NEMA 7/9 electrical rating).
The goal was to design a Bin that was completely enclosed, required little or no operator intervention and could be transported to landfill without opening until arrival at the landfill.
Design Parameters
Parameter | Screenings | Grit | Total |
---|---|---|---|
Feedrate: | 2.1 m3/hr | 3.0 m3/hr | 5.1 m3/hr |
Density: | 1000 kgs/m3 | 1400 kgs/m3 | 1000-1400 kgs/m3 |
Storage Capacity: | – | – | 15 m3 |
KWS Advantages
KWS designed and manufactured an integrated design of all components and assemblies which required expertise with; fabrication (dumpster enclosure), screw conveyor manufacture (leveling screw), instrumentation, motion sensors, level sensors, overload protection, controls, explosion proof control panel.
Special Features
Totally enclosed, self-leveling Bin that requires little operator operation. When the Bin is moved into location, the operator “plugs-in” the Bin using an explosion proof plug on an umbilical cord from the plant controls. The Bin loads and warns the operator in a remote control room that the Bin is nearing full condition. The leveling screw ensures that the Bin volume is used efficiently.
