Model Study of Mixing in the Proposed Dechlorination Facility of the Blue Lake Wastewater Treatment Plant Near Shakopee, Minnesota

The Blue Lake Wastewater Treatment Facility is located northeast of Shakopee, Minnesota, on Highway 13. Recent plans to upgrade the facility include the addition of disinfection basins and a dechlorination channel. The· dechlorination uses an S02 solution which is injected through a multiport diffuser in the bottom of the dechlorination channel. The dechlorination channel and the S02 feed are shown in the plan layout in Fig. 1-1. The elevations in the prototype (full scale) are shown in Fig. 1-2.
