1  INTRODUCTION

Water Treatment shall cater to the needs of both Camau 1 & Camau II for Boiler feed and potable water needs. Water from Municipal water supply (Filtered water) is treated in the Pretreatment system before it is divided into two streams, one for Boiler feed treatment and the other for Potable water treatment. The plant essentially consists of the following three systems:

1.  Pretreatment System
2.  Demineralisation System
3.  Potable water System
