Secondary treatment is the heart of most wastewater treatment plants. Many biological treatment options are available. Selection of the best fit for a particular application depends on many factors including influent and effluent criteria, effluent disposal or reuse, site availability and constraints, energy costs, solids disposal or reuse alternatives and operator preference.
