  • Wastewater Treatment Method
    Publication number: 20170313604
    Abstract: Provided herein are methods of reducing microbial concentrations in water with a peracid disinfectant. The method can include the steps of measuring the quality of the water in real-time and dosing the water with a first dose of a peracid disinfectant; measuring the peracid disinfectant demand; and adding one or more subsequent doses of the peracid disinfectant. The subsequent peracid disinfectant dose can be controlled by a processor-based controller based on peracid disinfectant demand.

  • WASTEWATER TREATMENT METHOD
    Publication number: 20150005379
    Abstract: The present invention relates to a method for treating wastewater comprising adding a peracid to such wastewater after such wastewater has undergone a filtration step, characterized in that said peracid is added to said wastewater at a first peracid addition point; as well as at one or more subsequent peracid addition point(s) placed at sequential location(s) in a contact chamber. It has been unexpectedly found that such sequential addition is more effective than adding such peracid at a single location.
