Hammerhead On-site Screen Sizing (HOSS) Testing
Together with our partner, Hydro-Dyne Engineering, Process Wastewater offers on-site screen testing.

While the wastewater industry has evolved, the methods and formulas for headworks design and equipment sizing have remained constant. As a result, treatment plants and collection systems continue to deal with ongoing and unnecessary problems including equipment failure, and a significant reduction in overall system efficiency and performance.

On-site screen sizing provides significant information that can influence the way treatment plants design their headworks structures.

Hydro-Dyne’s Hammerhead On-site Screen Sizing (HOSS) equipment utilises an array of technologies to test and analyse a treatment plant’s unique wastewater environment, resulting in informed decisions about headworks structure design and ultimately reducing costs and improving performance and efficiency.
