Managing Toxic Coke & Steel Wastewater with Resilient MBBR Technology

Wastewater from coking and steel manufacturing is among the most challenging industrial streams to treat. Coke quenching, gas scrubbing, and finishing processes produce a highly toxic, complex mixture of contaminants that can overwhelm conventional biological systems.

• High-concentration ammonia: Requires efficient nitrification to prevent severe environmental damage.
• Cyanides and thiocyanates: Highly toxic compounds that require specialized bacteria for treatment.
• Phenols and PAHs: Carcinogenic, difficult-to-degrade organic compounds.
• Variable loads: Batch processes and production changes can create shock loads that cause traditional plants to fail.

The Ecologix Moving Bed Biofilm Reactor is well suited to coke and steel wastewater. Rather than relying on suspended growth, it supports a large bacterial population in a protected, fixed-film biofilm on proprietary biocarriers.

Outer biofilm layers absorb toxic shocks and protect specialized microbes within. This resilience enables distinct bacterial communities in different zones, supporting a compact, multi-stage process for removing ammonia, phenols, and cyanides.
