The Stillwater Wastewater Treatment Facility is located in Oak Park Heights, Minnesota. Current plans to modernize the facility include the replacement of the existing disinfection (chlorination) basin and an upgrade to include a dechlorination system and basin. The dechlorination process uses an S02 solution that is injected through a mUltiport diffuser into the dechlorination channel flow. Adequate mixing of the S02 solution is necessary for contact and deactivation of the chlorine residue.
