Guidelines for Grit Sampling and Characterization addresses the "last frontier" in liquid systems treatment by documenting and examining the methods currently in use. Driven by the industry's increasing need to determine how grit can be better characterized, modelled, and reliably removed, this book is a first step toward understanding the implications of the methods selected and allowing for proper design and optimization of grit removal systems.The book discusses methods for: Characterizing grit. Obtaining a grit sample, including: Cross-channel sampling and dry sieving/ Full-depth sampling and wet sieving. Primary sludge sampling. Analyzing a grit sample. Using grit characterization data. The authors also identify gaps in the current knowledge and make the case for further research in critical areas.
