Once operational, the pilot plant's first runs will investigate the impact of modifying operating parameters, including chemical coagulation and flocculation, on Lake Huron water. It will be the first step in assessing our ability to switch from conventional treatment to direct filtration treatment. Subsequent projects at the pilot plant will include training for GLWA t...
