SWA Water is Providing World-Class, Sustainable Wastewater Solutions – For Textile Production in China

At SWA Water, we’re passionate about providing innovative and reliable industrial wastewater treatment solutions that empower businesses to operate sustainably. We partnered with Panyu EPB on a significant project – upgrading the existing industrial wastewater treatment plant (WWTP) servicing 20 textile companies in Panyu, Guangzhou, China.

This project exemplifies SWA Water’s commitment to delivering exceptional Design & Construct (D&C) services. We collaborated closely with Panyu EPB to ensure a seamless upgrade that not only doubled the plant’s capacity but also optimised treatment processes for the textile industry’s specific needs.

Understanding the Challenge

The existing WWTP was treating 15,000 cubic meters (m³) of wastewater daily. However, with the growing textile industry in Panyu, the plant needed an upgrade to handle double the capacity – 30,000 m³/day. Additionally, textile wastewater often presents unique challenges, including high colour content, Chemical Oxygen Demand (COD), suspended solids (SS), and turbidity.

A Tailored Solution

SWA Water’s D&C expertise allowed us to deliver a comprehensive solution encompassing all aspects of the upgrade:

Design: Our team of experienced engineers meticulously designed a treatment process that effectively addressed the specific needs of textile wastewater. This included:

  • Inlet Screening: Removing coarse solids to protect downstream equipment.
  • Pump Well: Efficiently transferring wastewater throughout the treatment process.
  • Chemical Flocculation: Utilising coagulants and flocculants to remove colour, COD, SS, and reduce turbidity.
  • Primary Clarifiers: Settling out heavier solids before biological treatment.
  • Biological Treatment: Employing a biological process to remove organic pollutants and achieve optimal effluent quality.
  • DAF Sludge Thickeners (1 x 200 m³/h): Thickening sludge before dewatering, reducing disposal costs.
  • Belt Filters (2 x 2m wide): Dewatering sludge into a manageable form for disposal or further processing.
  • Control System (Siemens PLC & SCADA): Implementing a sophisticated control system for automated and efficient plant operation.


  • Manufacture: SWA Water’s state-of-the-art manufacturing facilities ensured the highest quality equipment was fabricated to meet precise specifications for the project.
  • Construction: Our team seamlessly integrated the new equipment with the existing plant, minimizing disruption to ongoing operations.
  • Testing & Commissioning: Rigorous testing and commissioning ensured all systems functioned optimally before final handover.

Keeping Operations Running

A crucial challenge of this project was maintaining full 24/7 operation of the existing plant while the upgrade was underway. SWA Water’s experienced construction team meticulously planned and executed the project in phases to minimise downtime and ensure continuous wastewater treatment for the textile companies.

The Outcome

The successful completion of this project has resulted in a significantly enhanced wastewater treatment facility for the Panyu textile industry. Key achievements include:

  • Doubled Capacity: The plant can now effectively treat 30,000 m³ of wastewater daily, catering to the growing needs of the textile sector.
  • Improved Treatment Efficiency: The advanced treatment process effectively removes colour, COD, SS, and turbidity, ensuring compliant and environmentally responsible wastewater discharge.
  • Operational Efficiency: The Siemens PLC & SCADA control system facilitates automated and efficient plant operation, reducing operating costs.
  • Reduced Environmental Impact: The upgraded plant minimizes the environmental impact of the textile industry in Panyu by treating wastewater to a high standard.
