The use of Thermal Energy Storage (TES) tank that currently being practice byGDC UTP has becomea widelyaccepted method for the productionand storage of chilled water for air conditioning cooling. However in 2009, GDC UTP's TES has detected having high turbidity which is higher than 300 NTU and accumulation of sludge at bottom ofthe tank due to no clarification system for chilled water system for 10 years. This accumulation of sludge will be starting point of heat transfer failure and corrosion cell. This project will investigate a suitable clarification system that would help to achieve reducing the turbidity and total iron value in TES tank into desirable range. Coagulation & Flocculation and Dissolved Air Floatation (DAF) system only being take into our consideration because this project will focus toward turbidity as an indicator that we want to reduce. Based on the experiment carried out through this project, Coagulation- Flocculationis very good approach to be implemented for water treatment for GDCUTP Chilled Water System compared to Dissolved Air Floatation. Results oftreated water by Coagulation - Flocculation shows around 20 NTU which is already below 30 NTU, allowable specification turbidity for chilled water in GDC UTP.
