  • Treating pharmaceutical wastewater - Case Study

    A pharmaceutical facility in the Caribbean had an existing wastewater treatment process that utilized a sequencing batch reactor (SBR). SBRs use large tanks to collect wastewater, then a number of different options can be employed to treat the water (such as chemicals addition, aeration and mixing). When an SBR aerobically breaks waste down, it can produce a high volume of air that needs to be ...

  • Case study - CAIROX Potassium Permanganate

    BACKGROUND The Carbondale Water Treatment Plant (Carbondale, Illinois) with a design capacity of 8 MGD and an average flow of 4.6 MGD draws its water from Cedar Creek Lake. Because of moderately high raw water TOC levels (4.3 - 6.5 mg/L) and low alkalinity (36 - 40 mg/L as CaCO3), Carbondale is required to attain 45 percent TOC removal under the Disinfection/Disinfection By-Product ...
