Grit vs. Grit. A Pilot Evaluation Comparing Two Grit Removal Technologies
Abstract:The Army Base wastewater treatment plant (ABTP) is an 68 ML/d (18 MGD) secondary wastewater treatment facility. ABTP is currently undergoing design for advanced biological nutrient removal. The design will install a new pre-treatment facility (PTF) with grit removal. The owner desired to improve the grit removal facilities as the original grit channels were ineffective.
The design of the new PTF is space constrained for the given site. Manufacturers of a gravity settling unit and a forced vortex unit were contacted to conduct a side by side pilot test. The goals of the study were to evaluate: manufacturers expected efficiencies, the grit removal efficiencies over a full range of grit particle sizes from 100 μm to 300 μm, and compare efficiency of removal with cost of grit removal unit. Based on the pilot testing results, the municipality is proceeding with full scale designs for the gravity settling unit.
