41. New Insights Into Waste Lagoon Water Mixing 8/31/2012

    All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented.

42. Just Add SCADA 8/31/2012

    Internet-hosted SCADA systems are a modern answer to modern municipal water and wastewater concerns. By Thelma Akwei and Ben Manlongat

43. Microbiology: The Key To Wastewater Treatment 8/31/2012

    The biological treatment of wastewater relies mainly on a consortium of heterotrophic and autotrophic bacteria. Collection system bioaugmentation aims to introduce high concentrations of specific soil bacteria into the outer reaches of the sewer system and amplify the beneficial effects of soil bacteria in the collection system. By Bulbul Ahmed, Andrew Newbold, and Rich Schici

44. An Evaluation Of Low-Energy Treatment Schemes For Water Reuse 8/31/2012

    The production of reclaimed water from municipal wastewater is now standard practice and almost universally accomplished using primary treatment (discretionary), secondary treatment with activated sludge, filtration, and disinfection with chlorine, sodium hypochlorite, or ultraviolet light (UV) disinfection. By Erin Mackey and Andrew Salveson

45. Trace Organic Compounds: What Goes In Must Come Out 8/31/2012

    Chemically enhanced high rate settling (CEHRS) shows promise in removing harmful compounds such as pharmaceuticals and consumer products from wastewater. By Daniel M. Austria

46. Corrosion In Wastewater Systems: More Than One Bug 8/31/2012

    The role of various bacteria in the destruction of concrete in wastewater systems has been recognized since 1945. Already susceptible to old age, wastewater infrastructure systems are also threatened by corrosive bacteria — but they needn't be. By Heather Ramsey, John Davis, and Gary Hall

47. Wastewater 2.0: The Age Of Innovation 8/30/2012

    Thanks to some forward-thinking pioneers and early adopters committed to innovation, the wastewater industry is on the precipice of radical change.

48. The Next Frontier: Automating By Water Quality 9/19/2011
    Since the early 1970s, water and wastewater plants have been automating processes in order to achieve a more stable effluent and to decrease costs. By Bob Dabkowski, Hach Company
49. Innovative And Cost-Effective Solutions For Activated Sludge And Nutrient Removal Applications 9/19/2011
    Municipalities across the nation grapple with the treatment challenges associated with escalating state and federal regulatory requirements on the heels of limited or declining budgets. By Ayman Shawwa, P.E., Ph.D., BCEE, PMP, Aeration Industries International
50. Waste Lagoon Rehabilitation A New Look At An Old Problem 9/19/2011

    Throughout the last half-century the municipal and industrial wastewater treatment industry has depended heavily upon the use of waste lagoons in order to provide relatively clean water that could be returned to the environment. These are often called stabilization lagoons.
