Onsite wastewater treatment systems collect, treat, and release about 4 billion gallons of treated effluent per day from an estimated 26 million homes, businesses, and recreational facilities nationwide (U.S. Census Bureau, 1997). These systems include treatment units for both individual buildings and small clusters of buildings connected to a common treatment system.
This 1-hour online course presents the design considerations for disinfection for onsite systems.Disinfection for onsite systems is typically accomplished using either chlorination or ultraviolet disinfection.The material for this course is taken from a recently published EPA document on Onsite Wastewater Treatment.The course also includes a reference section for use by the student.
This course includes a multiple-choice quiz at the end.
At the conclusion of the course, you will understand:
Describes the types of chlorine available for disinfection.
Explain the advantages and disadvantages of each type.
State the recommended chlorine dosage for disinfection.
Describe the factors that affect the use of UV disinfection for onsite wastewater applications.
