1.0 INTRODUCTION
The purpose of this Continuous Improvement Project (CIP) is to tackle 2 major problems that were found due to
the secondary clarifiers. The first one was the amount of algae growth on the weirs and effluent channel. The
second problem was the amount of time we spend dealing with the algae. The algae would break off naturally
and affected the sampling result for SS.
In additional, manually work to clean the algae has made the plant is not safer place in which to work. Operators
will highly potential to exposure to harmful chemicals and biological hazards as well as slipping and falling while
cleaning the tanks.
Furthermore, operators had spent a lot of time to clean the algae manually and it has affected the other works
which also important to attend. If the problem of time taken can be reduced, the operators has sufficient time todo other works such process control, ground maintenance, housekeeping and finally minor PPM works and in
other word it has allows operator time to be better utilized.
Therefore, we come out with a solution to invent a special self cleaning device which is EFFICIENT, SIMPLE, IM-
PRESSIVE AND ECONOMICAL. The device is named as CSC Clarifier Self Cleaning. Below is the Technical draw-
ing of the CSC:

2.0 PROCEDURES
This Standard Operating Procedure (SOP) is to be used as a standard practice on how to improve the cleaning
algae at clarifier and to minimize the extensive use of manpower and finally to optimized the time taken for op-
eration & maintenance works. The selection of STP is shown in Flow Chart 1.

3.0 CONCLUSION
This SOP is a guideline of the procedures used during implementation of the Continuous Improvement Project
(CIP) at UO Skudai.This SOP is design to ensure the user are knowledgeable to make a justification on where and
how to install the CSC at their STP. THE CSC is design for EFFICIENT, SIMPLE, IMPRESSIVE AND ECONOMICAL.
