Grit removal is a key pre-treatment step in many wastewater treatment plants. Inadequate historical design standards are evolving to more closely reflect real world conditions. The latest grit removal technologies therefore demonstrate significantly improved performance. With huge variations between performance test methods however, who really knows? And if you're trying to remove grit, why measure organics? The new frontier of grit removal is increasingly thought to be about grit purification. This new awareness resulted in an innovative technology being introduced in 2018, which has grit purification as a fundamental design principle. This presentation provides an up to date understanding of wastewater grit, and explains the fundamental things you should know, including two important things that you probably didn't know before.
