October 7, 2022: Clearwater BioLogic announces a new and revised Step 2 in its three-step sulfate treatment process. After Step 1 generates hydrogen sulfide through biological reduction, Step 2 now uses reactive iron treatment: the hydrogen sulfide is bonded with iron without the addition of any other chemicals, and in Step 3, the iron sulfide is removed.  This new reactive iron technology dramatically reduces the cost of installing and operating the Clearwater BioLogic system. More details are coming soon.
