How do warmer temperatures affect the biological activity in a trickling filter?

Warmer temperatures generally have a positive effect on the biological activity within a trickling filter. This increase in temperature enhances the metabolic rates of the microorganisms that are essential for breaking down organic matter in wastewater. As the environmental temperature rises, the biological processes, including the rates of respiration and reproduction among bacteria, tend to accelerate.

This boost in microbial activity leads to improved treatment efficiency, as microorganisms can more effectively decompose organic pollutants, ultimately resulting in higher quality effluent. As a result, the system can handle a greater organic load, which is crucial for effective wastewater treatment. Therefore, in this context, the correct answer indicates that warmer temperatures enhance biological activity, contributing to better treatment outcomes.
