Kaizen Examples

1. Flow Sludge Project

Running the sludge press system cannot increase the Flow Sludge Belt Press, due to the pipeline conveying sludge from Mixing Tank to Belt Press, there is no slope down to Belt and often has sludge clogged in the pipe, resulting in sludge drainage and sludge overflow from Mixing Tank.

Therefore, improvements were made by designing the slope receiving sludge from the Mixing tank and improved to be an open track instead of a pipe, resulting in increasing the amount of sludge entering the Belt Press system and reducing the cleaning of the work area due to sludge overflow from the Mixing tank.

A Performance Comparison Before - After

Details	Before	After	Increase/Decrease (%)
Capacity of sludge	5 cubic meter / hour	15 cubic meter / hour	Increase 200%
Reduce cleaning in the work area	3 times / week	None	Decrease 100%
Reduce the cost of electricity consumption	70,954 baht / month	23,651 baht / month	Decrease 66.67%

2. Sludge Injection Equipment Project

Currently, the tap water treatment plant is an open system, resulting to dust flying in the air accumulating on the surface of the Sand Filter Tank, and cause deposits to accumulate on the walls of the sand filter tank. The workers require using the water hose and bow the head, which is to clean, it takes a long time and may cause a hazard during the operation. Therefore, the Company invented a device for injecting sludge and sand deposits on the filter tank resulting to the number of workers, operation time and risks were reduced.
