This online engineering PDH interactive presentation an overview of biological wastewater treatment, a general description of the activated sludge process, information about several variations of the activated sludge process, discussion of design calculations for an activated sludge aeration tank, and discussion of activated sludge operational calculations, discussion and detailed examples of process design calculations for a single stage BOD removal MBBR (moving bed biofilm reactor) system, a two-stage BOD removal MBBR system, a single stage tertiary nitrification MBBR system, a two-stage BOD removal/Nitrification MBBR system a post-anoxic denitrification MBBR system and a pre-anoxic denitrification MBBR system.
The activated sludge process is very widely used for biological wastewater treatment. In a sewage treatment plant, the activated sludge process is a biological process that can be used for one or several of the following purposes: oxidizing carbonaceous biological matter, oxidizing nitrogenous matter, and removing nutrients.
The MBBR process is an attached growth process that uses plastic carriers to provide a surface on which biofilm grows. It can be used for BOD removal, biological nitrification, biological denitrification, and biological phosphorus removal.

This online engineering PDH interactive presentation provides a basic overview of the elements essential for the development of a sound management program for decentralized wastewater systems that is specifically suited to your community.
One in every four households in the United States relies on an individual onsite or small cluster system to treat wastewater. In far too many cases, these systems are installed and largely forgotten – until problems arise. An effective wastewater management program, if properly executed, can protect public health, preserve valuable water resources, and maintain economic vitality in a community.
To facilitate proper management, EPA published Voluntary National Guidelines for Managing Onsite and Clustered (Decentralized) Wastewater Treatment Systems.
This presentation assists with implementing the guidelines and is intended as a guide for communities that have evaluated a full range of wastewater options and determined that decentralized wastewater treatment is the most cost-effective and appropriate long-term option. It also provides links to extensive resources for more thorough investigation of particular topics or management program elements.
