Biological Treatment Systems

Biological treatments rely on bacteria, nematodes and other small organisms to break down organic wastes using normal cellular processes. Wastewater typically contains a buffet of organic matter — garbage, wastes and partially digested foods — and may also contain pathogenic organisms, heavy metals and toxins. The goal of biological wastewater treatment is to create a system in which the results of decomposition are easily collected for proper disposal. Biological treatment is used worldwide because it is effective and more economical than many mechanical or chemical processes.
