Executive Summary
Facing the dual challenge of limited land and stringent discharge standards, a major industrial wastewater facility in China’s environmental hub implemented a high-performance Moving Bed Biofilm Reactor (MBBR) upgrade. By integrating HNS High-Surface Area Media, the plant achieved deep denitrification and stable compliance for high-strength chemical and dyeing wastewater without expanding its physical footprint.
Project Profile: The Challenge of Complex Influent
- Project Name: Project EH-Wuxi
- Total Capacity: 50,000 $m^3/d$
- Influent Profile: High-concentration organic matter from 80+ industrial enterprises, primarily Printing, Dyeing, and Chemical sectors.
- Regulatory Standard: Taihu Lake Discharge Standard (DB32/1072-2018)—one of the world’s most rigorous environmental mandates.
Technical Solution: Integrated AAO/AOA + MBBR
To meet advanced Nitrogen (N) and Phosphorus (P) removal goals, the facility utilized a multi-stage MBBR strategy:
- Phase I: AAO + MBBR process for enhanced biological activity.
- Phase II: Advanced AOA + MBBR process for deep denitrification.
- The Hardware: HNS Bio-Media with an effective protected area of $>800\text{ m}^2/\text{m}^3$.
Why Leading Engineering Firms Choose HNS WaterTech
As a global MBBR media manufacturer exporting to Mexico, Brazil, Poland, and Italy, HNS WaterTech provides more than just hardware:
1. 100% Virgin HDPE for 20-Year Durability
Our media is manufactured exclusively from 100% Virgin HDPE, ensuring zero breakage or clogging since the plant’s upgrade in 2014. This is critical for DBOOT (Design-Build-Own-Operate-Transfer) models where long-term OPEX stability is a priority.
2. Massive CAPEX Savings
By increasing biomass concentration within existing tanks, our high-surface-area media allows plants to expand capacity without land acquisition, significantly reducing civil construction costs.
3. Production Reliability
Equipped with 30 high-speed automatic extrusion lines, we offer a daily output of 10-12 tons, providing a stable supply chain for large-scale global projects.
Manufacturer’s Technical Support
HNS WaterTech acts as a strategic technical partner for engineering teams worldwide. We provide:
- Design Validation: Empirical performance data for kinetic calculations.
- Fluidization Expertise: Support for aeration layout and screen (sieve) specifications.
- Global Export Experience: Proven logistics and compliance in regions including Latin America, Europe, and the Middle East.
