Novel Treatment for Challenging Pharmaceutical Waste
Abstract:A new process for wastewater treatment has been developed at AstraZeneca's pharmaceutical wastewater treatment plant in Södertälje, Sweden. A multi-stage biofilm process, including a combination of micro-fungi and bacteria, was found to remove toxicity better than a conventional bacterial treatment. The full-scale plant has been in operation since October 1997 with good results. TOC is reduced by 95%, from an average of 633 to 33 mg/l. This flexible process is insensitive to disruptions and efficiently reduces toxicity as well as a number of recalcitrant organic substances.
