Abstract
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).
