The purpose of this study is to develop methods for rapidly and economically increasing the capacity of complete retention and/or intermittently discharging wastewater stabilization lagoons located at Corps of Engineers recreational sites through in situ application of chemical coagulating agents. Alum was chosen as the coagulant in this study because it is relatively inexpensive and readily available. Application and mixing techniques were optimized using a 14-ft boat and small outboard motor. Analyses were performed to determine treatment efficiencies for biochemical oxygen demand (BOD5), chemical oxygen demand (COD), suspended solids, total phosphates and orthophosphates. Algae enumerations were also performed. The study took place over an entire year with three coagulant applications performed to study the long-term effects of in situ alum addition. In situ alum addition consistently produced effluents with phosphate concentrations below 1.0 mg/alum. Removal rates for BOD and COD were approximately 80 percent with suspended solids being removed at rates as high as 95 percent. Algae removal rates were as high as 95 percent. No adverse effects were seen in either lagoon performance or in spraying the effluents on vegetation as a result of alum addition. Sludge accumulations of 0.1 to 0.2 in. per chemical application were measured. Repeated applications of alum did not result in significant increases in the sludge thickness, and no long-term adverse effect on lagoon performance is expected.

Pond treatment technology is used in tens of thousands of applications serving many millions of people across the globe - why? Simply because it is efficient and effective. While pond treatment technology offers relative simplicity in its application, it incorporates a host of complex and diverse mechanisms that work to treat and cleanse polluted waters before their return to our environment. This book offers a comprehensive review of the pond technology field including the newest ideas and latest findings. Topics covered include: The physical, chemical and biological characteristics of the pond environment; A detailed review of pond treatment mechanisms and performance; Comprehensive guidance on pond design, operation and upgrade options; A range of chapters summarising new and emerging pond technologies; The integration of ponds with wetlands and aquaculture systems and their use as storage reservoirs; Special applications of pond technology in cold climates, for agricultural wastes and for treatment of stormwater. The objective of this book is to get this wealth of knowledge "out there" to the users to ensure the continuous improvement and ongoing success of this crucial technology.
