Abstract

Grit is removed from a wastewater system to protect moving mechanical equipment from abrasion and wear, to reduce conduit clogging, and to prevent loading of treatment works with basically inert matter, there are many different types of wastewater grit removal chambers. They can be divided into three basic types: velocity controlled. Aerated, And constant level short term sedimentation tanks. Inclined plate and tube settlers are constructed to be used in one of three ways with respect to the direction of liquid flow relative to the direction of particle settlement: countercurrent, cocurrent and cross-flow. In this paper the installation of cross-flow inclined plates in velocity controlled grit removal chambers to reduce chamber length, improve removal efficiency and facilitate cleaning of chamber from deposited grit has been suggested and discussed.
