What is One of the Main Challenges of Treating Industrial

Question

What is one of the main challenges of treating industrial runoff versus municipal wastewaters?
A) more solid waste
B) higher oxygen concentrations
C) toxic chemicals
D) higher organic loads
E) lower oxygen concentrations

Accepted Answer

One of the main challenges of treating industrial runoff is the presence of toxic chemicals that are not typically found in municipal wastewaters. These chemicals require special treatment processes to remove them from the water before it can be discharged safely. The other options listed (more solid waste, higher organic loads, higher/lower oxygen concentrations) can be challenges in both industrial and municipal wastewater treatment, but the presence of toxic chemicals is a unique challenge to industrial wastewater treatment.
