Wastewater Treatment Pond Improvement Project

The wastewater treatment pond of Building B, after being fully operational, revealed several areas that were difficult to operate, leading to a risk that certain monthly water quality measurements might not meet future standards. Additionally, the equipment used in the system consumed a high amount of electricity. Therefore, the Engineering Systems Department proposed improvements to enhance operational efficiency and prevent future issues by implementing the following measures:

1. Addition of Equalization Tank This eliminates the need for an Ejector Pump in the wastewater treatment process, resulting in improved operational efficiency, reduced energy and maintenance costs, and enhanced sustainability in the Company's water resource management.

Performance Results

• Reduced electricity consumption by 10,656 kWh per year.
• Saved electricity costs by 53,280 Baht per year.

2. Replacement of Aeration Pump The aeration pump for the wastewater treatment pond originally installed in the project was an Ejector Pump. During operation, there were multiple instances where the equipment did not function properly, resulting in insufficient oxygen supply. Additionally, the existing pump consumed a high amount of electricity, necessitating its replacement with an Aerator Pump.

Performance Results

• Reduced electricity consumption by 25,776 kWh per year.
• Saved electricity costs by 128,880 Baht per year.
