Abstract

The optimized, tailored approaches in the design of wastewater treatment plants (WWTPs) minimize expenditure of the resources, increase treatment effectiveness, and prolong useful life of the infrastructure. In this study, wastewater grit characteristics were evaluated over the course of one year at the headworks and collection network of the Atlantic County Utilities Authority (ACUA) WWTP, located in New Jersey, USA. The mixed grit at the ACUA WWTP can be characterized as particles prevalently in the fine sand size range with high content of organic matter, low fraction of fats, oils, and grease (FOG), and very low settling velocity. A significant seasonal variability was observed in the measured parameters. These results will be utilized in the design of the most effective, fiscally responsible, and sustainable method of grit removal at the study site and may serve to promote utilization of WWTP-specific design at other facilities.
