Prof. Grit may cause problems in: Pumps Sludge digestion Dewatering facilities In addition, it may settle out in downstream pipes and processes The grit removal process is carried out at an early stage of treatment because: The particles cannot be broken down by biological process The particles are abrasive and wear down equipment14/02/01 Assoc. Prof. Grit chambers are designed to remove inorganic solids > 2 mm Removal is commonly effected using: Settlement Separation using a vortex Settlement in the presence of aeration (to keep the lighter organic particles in suspension) There are important hydraulic principles associated with each of these14/02/01 Assoc.
