Optimization of Actiflo system for Portage La Prairie water treatment plant

Water treatment plants in Manitoba use surface water with high organic content as their source of water supply. Organic carbon reacts with disinfecting chlorine forming potentially carcinogenic disinfection byproducts. Portage la Prairie water treatment plant is an example of typical Manitoba lime/soda water treatment plants facing the challenge of removal of organic carbon. Coagulation and Granular Activated Carbon (GAC) are used in this plant for removal of Dissolved Organic Carbon (DOC).

Our previous studies showed that DOC cannot be efficiently removed by these two processes.

Water Stability Control for Optimization of Filtration at Portage la Prairie and Sanford Water Treatment Plants

There are about 180 public water treatment plants in Manitoba relying on surface water as their source of supply. Optimization of water treatment processes offers many operational savings for these plants. Portage la Prairie and Sanford water treatment plants are examples of typical Manitoba water treatment plants. Both plants utilize lime/soda softening processes to remove water hardness. The softening process requires serious water pH control, otherwise it can lead to the precipitation of calcium carbonate particle that causes excessive wear on filters, among other consequences.
