MODIFICATION OF MODEL SEDIMENTATION TANK

MODIFICATION OF MODEL SEDIMENTATION TANK

ABSTRACT

The project done was the modification of model sedimentation tank. The equipment was made of maslte metal of 16 gauges thickness. Two valves was connected, one for water inlet and the others for water out let at the bottom of the tank. Pumping machine was connected fro pumping in of water into the system. Evolutional test which entails the testing of the constructional work in order to know whether the component needs any adjustment was also carried out.   The maintenance procedure is written in the book to avoid constant failure during experimentation. At the end of the test of the modification work, it was seen that the machine is very useful to student for their laboratory experiment based on sedimentation process. The amount of experience gained and the understanding of students’ problems has therefore been methodology based on the production of this book.

CHAPTER ONE

INTRODUCTION

Sedimentation tanks, used on a continuously flowing basis, are widely used in water treatment plants. In general, the solid materials to be removed have very low settling velocities because of the small particle sizes and density differences together with the effects of hindered settling due to particle concentrations.
