What is another name for slime growth in trickling filters?

The term "zoogleal film" specifically refers to the layer of microorganisms that develops on the surfaces of filter media in trickling filters. This growth often consists of a complex community of bacteria, fungi, and protozoa that form a slimy layer, aiding in the treatment of wastewater by breaking down organic matter and other substances.

In the context of wastewater treatment, biological processes are crucial, and the formation of zoogleal films is a vital part of those processes in trickling filters. These films provide a habitat for the organisms that contribute to the biodegradation of pollutants, making the treatment process more efficient.

While "biofilm" is a general term that can describe similar growths in various biological treatment systems, "zoogleal film" is the more specific term associated with the distinct slime growth occurring in trickling filters. Other terms, such as "algal bloom" and "activated film," refer to different types of biological growth or treatment mechanisms that do not accurately capture the nature of the growth seen in trickling filters.
