Disinfection for Onsite Wastewater Treatment Systems The infiltration of partially treated wastewater effluent into the soil, a common practice for many onsite and decentralized wastewater management systems, has the potential to degrade groundwater quality. Of primary concern is the transfer of pathogenic constituents from infected individuals via wastewater to groundwater. Decentralized treatment systems that include... Learn More

Water and Wastewater Reuse Water-related problems are increasingly recognized as one of the most immediate and serious environmental threats to humankind. Water use has more than tripled globally since 1950, and one out of every six persons does not have regular access to safe drinking water. Lack of access to a safe water supply and... Learn More

Desalination for Drinking Water Desalination is increasingly being used to provide drinking-water under conditions of freshwater scarcity. Water scarcity is estimated to affect one in three people on every continent of the globe, and almost one fifth of the world’s population live in areas where water is physically scarce. This course introduces the concept of... Learn More

Water Treatment – Advanced Oxidation Processes Ultraviolet (UV) disinfection is receiving increased attention in the drinking water industry as a method for utilities to comply with upcoming disinfection regulations. This course presents an overview of the use of UV light and ozone for micropollutant control in drinking water. The micropollutants discussed include methyl tert-butyl ether... Learn More

Membrane Bioreactors for Wastewater Treatment Wastewater reclamation is gaining popularity worldwide as a means of conserving natural resources used for drinking water supply. The use of membrane bioreactor (MBR) technology, which combines conventional activated sludge treatment with low pressure membrane filtration, has been proven to be a feasible and efficient method of producing reclaimed water....
