Black Odorous Water Remediation Technology | Long-Term Eco-Restoration Solution

MOTIVA offers a proven “artificial kidney system” solution using catalytic oxidation and advanced treatment units, effectively eliminating black-odorous water, restoring water self-purification, and supporting long-term urban water ecosystem recovery.

Black and odorous water bodies are common in urban China, caused by excessive pollutants overwhelming the natural self-purification capacity of rivers. They disrupt urban landscapes, harm aquatic ecosystems, and threaten public health, affecting respiratory, circulatory, and digestive systems.

Key Challenge

While external sources are being addressed, internal (sediment) pollution remains a major hurdle. Treatment requires significant investment, with complex engineering making long-term management difficult.

Technical Solution

MOTIVA’s solution features an “artificial kidney system” (MOTIVA-JHC) that continuously extracts polluted water, processes it using our proprietary catalytic oxidation technology, and returns it to the river. The catalysts form strong oxidative radicals that react with organic pollutants, significantly improving degradation rates and water biodegradability.

The system achieves a COD reduction of 50%–75%, stabilizes water quality, and enables sustainable long-term restoration of urban rivers.

Process Advantages

1. Stable, automatic operation with no manual intervention
2. Enhances natural purification capacity for lasting results
3. Low capital and operating costs, scalable for large rivers
4. Effectively removes COD, ammonia, and color, ensuring compliance
