Removing organic materials that are captured along with the grit during separation is essential. Paying to landfill these residual organics is a tremendous waste of money. After all, processing organics is what your plant does best.  Additionally, organics remaining in grit introduce significant odor issues while stored at your plant.

Grit washing needs to effectively remove the attached organics without losing the captured fine grit particles. Hydro International’s TeaCup and SlurryCup use vortex flows and boundary layer separation to accomplish this difficult task. Both systems have no internal moving parts, which significantly reduces maintenance requirements. 

TeaCup - Advanced Grit Washing

The TeaCup has provided industry leading washing performance for hundreds of plants since 1976.  With no moving parts, the system functions entirely on hydraulic flows, which significantly reduces maintenance costs. In many plants, the TeaCup system can also be used for grit separation and is also highly effective in removing snail shells from trickling filter processes.

SlurryCup - Advanced Grit Washing and Sludge Degritting

The SlurryCup uses free vortex boundary layer separation to clean organics off of grit captured by a grit separation system. With no internal moving parts the system is low maintenance and built to last. Used in both headworks degritting and sludge degritting applications, the SlurryCup is a durable system that provides the protection that your plant needs to keep all of your plant processes operating at their peak capacity.
