Clean-water plants and their operating teams face increasingly strict regulations and ever-greater expectations for efficiency and resource recovery. Emerging technologies can help them meet both.Ralph “Rusty” Schroedel, P.E., BCEE, a wastewater engineering manager with AECOM’s engineering office in Milwaukee, Wisconsin, has observed a variety of advanced nutrient removal processes either being researched or applied commercially that can help treatment plants fulfill their obligations.The processes he describes deal with both the liquid and solids sides of treatment. Among his basic premises is that, “The future of wastewater treatment will be based on carbon management.” That means treatment must optimize energy use
