Water & Wastewater Treatment Plant Process Overview
Wastewater treatment methods vary greatly for many reasons. The volume and composition of the sludge in the influent, as well as how the sludge residue will be disposed of, all dictate design aspects of the plant.
A large volume of wastewater will preclude a simple batch system that might be appropriate for a smaller scale treatment facility. Sludge with low potassium or phosphorus content or loaded with heavy metals would not be suitable for land application.
The wastewater treatment plant allows solids to settle out and the remaining organic matter is broken down by microorganisms. Each area of the plant has a specific function.
