Treating industrial wastewater presents a unique challenge primarily due to the presence of toxic substances that can inhibit microbial activity. This characteristic is significant because many industrial processes generate effluents containing heavy metals, chemical solvents, and other harmful contaminants that can significantly affect biological treatment processes. In municipal sewage treatment, the waste is typically more organic in nature and includes biodegradable materials, making it easier for microbes to break down the substances effectively.

The presence of toxic elements in industrial wastewater not only disrupts the microbial processes essential for biological treatment but can also lead to the failure of treatment systems. This scenario requires special handling, treatment technologies, or pretreatment measures to mitigate the toxic effects, which complicates the treatment process.

In contrast, while factors such as treatment costs and regulatory requirements also play a role in wastewater treatment management, the chief difficulty faced in industrial contexts remains the toxicity and complexity of the wastewater itself, which necessitates tailored approaches and technologies for its effective treatment.
