Water Pollution Prevention and Treatment Guidelines and Wastewater Management

Water resources used in product manufacturing include industrial ultra pure water and steam, which are mainly used for equipment heating, heat exchange, heat recovery, equipment cooling, and power generation facilities, allowing raw materials to be made into high quality products through the manufacturing process.

FPCC's wastewater is treated by its wastewater treatment plant. FPCC's COD discharge per unit of product was 0.0117 kg/ton and SS discharge per unit of product was 0.0040 kg/ton, stably fluctuating compared with the past few years. This shows that biological treatment of wastewater has been mostly stable, but we will continue to improve the performance of wastewater treatment to ensure compliance with regulatory standards.

Historical Wastewater Discharge Monitoring Indicator

The effluent volume generated by FPCC throughout 2022 was 46.2 thousand tons per day. The quality of water eventually discharged into the Taiwan Strait met effluent standards after wastewater treatment. The volume of wastewater discharged per unit of product in 2022 decreased 2.2% compared to the previous year to 0.00054 million L/ton. In the future, we will continue to evaluate and develop wastewater recycling and reuse (e.g. collecting process sour water to the FGD system) and wastewater treatment facility modification to increase the volume recycled, in order to continue reducing the wastewater discharge per unit product.
