Recalcitrant COD reduction to < 30mg/L in pharmaceutical wastewater

Published on by in Technology

Screening various AOP's (advanced oxidation process) and other BAT's (best available technologies) to reduce the COD in the wastewater (200 - 300 gpm average to peak) from 100 mg/L to < 30 mg/L. The treatment train includes activated sludge treatment followed by an MBR. Looking at the following options:

  1. Ozone/Perozone
  2. UV Peroxide
  3. Activated Carbon
  4. Resins
  5. RO
  6. Ultrasonic
  7. AOP followed by a fluidized bed reactor (FBR)
  8. Wet Air Oxidation

I want to tap into your knowledge base to see if there are any other methods that are worth screening or experience someone has had with similar (pharmaceutical) wastewater and COD removal to very low levels.

  2. Dear Asher Benedict ,

    Thank you for starting an interesting discussion! I think a lot of experts would be interested in answering it and discussing various possibilities, and the best way to reach them would be to post it as a question instead of a discussion! Please, take it into a consideration.

    Best,

  3.  Есть технология очистки любой сточной воды и водоподготовки. Работает на основе специально организованных и взаимодействующих потоках. При взаимодействии потоки создают поле стоящей волны. И буквально разрывающее все загрязнения за счет резонанса. В поток всасывается атмосферный воздух. Кислород разрывается до одно атомарного состояния. Образуется и одно атомарный кислород и перекись и гидроксильная группа OH . Все загрязнения окисляются в воде, до инертного состояния

    There is a technology for cleaning up any wastewater and water treatment. It works on the basis of specially organized and interacting flows. In the interaction, the streams create the field of a standing wave. And literally tearing up all pollution due to resonance. The air is sucked into the stream. Oxygen is broken up to one atomic state. Formed and one atomic oxygen and peroxide and hydroxyl group OH. All contaminations are oxidized in water, until inert
