Disinfection Methods for CSO Treatment Overview Combined sewer overflows (CSOs) occur when flows exceed the hydraulic capacity of either the wastewater treatment plant (WWTP) or the collection system that transports the combined flow of storm water and sanitary sewage to the WWTP. When an overflow occurs, the excess flows tend to be discharged into a receiving body of water. CSOs typically discharge a variable mixture of raw sewage,  more...

Emerging Technologies for Biosolids Management Biosolids (sewage sludge) are the nutrient-rich organic materials resulting from treatment and processing of wastewater residuals. U.S. Environmental Protection Agency estimates that publicly owned wastewater treatment works (POTW) generate over 8 million tons (dry weight) of sewage sludge annually. New sewage sludge regulations reduces options for disposal and rising energy costs are causing a  more...

Wastewater Treatment Package Plants Overview In many cases, for small communities and individual properties, and especially where there are land area constraints, package wastewater treatment plants are a potentially cost-effective and efficient means for domestic and some commercial applications. This course reviews several of the most common types of package plants and includes process descriptions, advantages and  more...

Septic Tank Systems for Large Flow Applications Overview Often, in areas remote from centralized wastewater collection and treatment systems, septic tank systems are used for applications involving residential cluster systems, restaurants, nursing homes, and other commercial or institutional facilities. There is the potential to overlook important design considerations, which can differ substantially from the typical residential septic system.  more...

Alternative Wastewater Collection Systems - Low Pressure and Small Diameter Gravity Sewers Overview This course includes guidance and considerations on the selection of alternative wastewater collection systems for suburban, rural and semi-rural settings and development areas where the use of conventional gravity sewers could prove to be prohibitively expensive. In the course material, the reader will review several of the most common types of alternative collection systems,  more...

Emerging Technologies for Conveyance Systems To meet the challenge of ongoing and even increasing needs for maintenance and repair, many public and private conveyance system owners and consultants are seeking innovative technologies to replace, renew, or extend the life of these critical systems. Sanitary and combined sewer overflows may be the result of improper installation, age and chemical deterioration, or insufficient operation and  more...
