Textile manufacturing is a vital industry, but it comes with a major challenge: treating the complex and highly colored wastewater it produces. In Huzhou Lianshi Industrial Park, China, a groundbreaking wastewater treatment project has turned this challenge into a success story, setting a new standard for sustainable industrial practices.

The Textile Wastewater Dilemma

Huzhou Lianshi Industrial Park is a hub for textile factories. For years, the park struggled with wastewater treatment using outdated methods that failed to meet environmental standards. This led to conflicts with local rules and accumulated unpaid water fees. It was clear that a new approach was needed.

Innovative Solutions for Textile Wastewater Treatment

The park adopted an innovative textile wastewater treatment system designed to address its specific challenges:

• Advanced Oxidation: The new system uses advanced oxidation to break down stubborn pollutants and reduce color intensity.

• Enhanced Phosphorus Removal: Chemical treatment effectively lowers phosphorus levels in the water.

• Cost Efficiency: The upgraded system reduces chemical usage and energy consumption, lowering treatment costs to just 0.5-0.8 USD per cubic meter.

Transforming Textile Wastewater Treatment: The Results

The impact has been remarkable:

• Improved Water Quality: The treated water now meets strict environmental standards, with reduced COD (≤50 mg/L), color (≤15 times), and phosphorus (≤0.5 mg/L) levels.

• Cost Savings: The park has significantly reduced its wastewater treatment costs and eliminated penalties for non-compliance.

• Environmental Benefits: Cleaner water discharge has reduced pollution and improved the park's environmental footprint.

Textile Wastewater Treatment Flow Chart

Dric purifies industrial wastewater from the textile industry using the following methods: It begins with preliminary steps to remove large particles and adjust water quality. Primary treatment follows, focusing on neutralization and sedimentation to remove smaller particles. Secondary treatment uses biological processes to break down organic matter. Tertiary treatment further refines the water through filtration and advanced oxidation. The process concludes with sludge treatment and water discharge or reuse.

The Future of Textile Wastewater Treatment

The success of the Huzhou Lianshi Industrial Park demonstrates that even complex wastewater challenges can be overcome with the right technology and approach. This project not only resolved a long-standing issue but also set a new benchmark for sustainable wastewater treatment in the textile industry. As environmental regulations become stricter, industrial parks worldwide will need innovative solutions to manage wastewater. The story of Huzhou Lianshi Industrial Park offers valuable lessons: with the right technology and strategy, it is possible to achieve compliance, cost savings, and sustainability.
