Use of pilot plant in water treatment plant design
University of New Brunswick
Water for the Greater Moncton Metropolitan Area is supplied mainly from surface reservoirs fed by wells. The Turtle Creek Reservoir which today supplies the majority of Moncton's water is the primary focus of this report. Pilot and plant scale testing is beneficial in the development of alternative water treatment schemes. In other words, predesign studies document the major engineering decisions for the project, including evaluation criteria, selection of treatment processes, and basis for design. The processes encompassed by the term "water treatment" include turbidity removal, softening, removal of iron and manganese, trihalomethane (THM) treatment, colour removal, treatment for taste and odour, and disinfection. This report will determine the best alternative method of treating water at a prototype scale. The use of coagulants and coagulant aids are also evaluated to find the most economical coagulant. These results are then interpreted and analyzed in order to help in the design, treatment process, and plant layout (original and future considerations). The design and assembly of the pilot filter study has been established and operational since September 1990, while the first tests were done at different time intervals which included four series of test runs to determine seasonal variations (in January, April, July and October 1991).
