The Zhongli Wastewater Treatment Plant in Taiwan faced significant challenges in treating industrial wastewater reliably. The existing treatment system struggled with increasing pollutant loads and operational inefficiencies. Expanding the facility was not feasible due to limited space, necessitating an advanced treatment solution that could operate within the existing plant footprint.

Key challenges included:

• Inconsistent water quality: The old system couldn't guarantee to meet regulatory discharge standards.

• Limited space for upgrades: No room for conventional expansion.

• High industrial wastewater load: Diverse industrial sectors generated complex wastewater compositions, requiring an efficient and robust treatment solution.

Solution Proposals

To address these issues, the plant was upgraded with a MYTEX MBR Membrane Bioreactor (MBR) system, integrating advanced filtration processes into the existing infrastructure.

Key project features:

• Advanced MBR Technology: Replaced conventional treatment with MYTEX MBR for improved filtration and pollutant removal.

• Compact Design: Integration of 52,000m² 

• membrane area enabled a high treatment capacity (20,000m³/day) without expanding the existing footprint.

• Process Optimization: Inclusion of key treatment steps: Screening - Aeration  -  Filtration

• Reliable Operation Model: A BOT (Build-Operate-Transfer) model over 5 years ensured smooth execution and operation.

• Efficient Water Management: Filtered water is discharged in compliance with local environmental standards.
