Getting the Most From Your Activated Sludge Process. The backbone of most wastewater treatment plants, activated sludge is still the most widely used biological treatment process. It’s also one of the most complex. Learn from real-life scenarios at five wastewater treatment plants how to optimize dissolved oxygen as well as reduce solids production. Then, put your activated sludge knowledge to the test against a super-sized Certification Quiz.

Resolving Dewatering Dilemmas. Economics often drives the selection of dewatering equipment, but a number of factors — including process improvements further upstream — can significantly boost performance. Read about a plant that curbed a filamentous bacteria infestation and improved solids settling by adding specially chosen bacteria at the headworks. Then learn more about an alternative technology by taking a tour of the largest municipal screw press dewatering facility in North America.
