Emerging Technologies for Biosolids Management
Raymond Ehrhard, P.E.
Overview
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
new wave of technologies to be introduced into this market. New equipment is
being developed and tested at a record pace. Wastewater treatment plants and
engineers are involved with evaluating the latest and best technologies for this
changing industry.
The study
material provides information on new technologies entering the market. This EPA
sponsored report looks at technologies for conditioning, thickening,
stabilizing, dewatering thermal conversion and drying of biosolids. It
presents the state of development, available cost information, associated
contact names, and related data sources for each technology.
This course provides the
student an opportunity to look at and evaluate the latest biosolids technologies
entering the market. The course is suitable for a student with basic wastewater
treatment knowledge or for an advanced student that needs to evaluate new and
emerging alternative biosolids management technologies.
The student is expected to
read and review the material contained in the EPA Document, EPA 832-R-06-005,
Emerging Technologies for Biosolids Management.
The student must take a
multiple-choice quiz consisting of thirty (30) questions at the end of this
course to obtain 6 PDH credits.
