3 - Application of biological and advanced oxidation processes (AOPs) for the remediation of wastewater laden with toxic pollutants

Abstract

Nowadays, there has been major concern globally about the treatment and reuse of wastewater, focused especially on the industrial sector. Apart from this, alternative sources of wastewater treatment are also being developed. With this concern, recent well-developed methods such as advanced oxidation processes (AOPs) are very effective and efficient compared to conventional methods in treating wastewater released from different industries that contains harmful, toxic, and recalcitrant organic compounds. AOPs are normally more expensive than other treatment technologies, but in combination with biological treatment, these costs can be significantly reduced. So, our present study aims at a combination of biological and tertiary wastewater treatment methods for the degradation and decontamination of toxic pollutants. The present work is especially focused on synthetic and industrial (pulp and paper) wastewater treatments. In addition, types of bacteria, their degradation impact, the catalyst impact, and the parameter effect on treatment efficiency are also discussed. Both these areas of wastewater treatment give an idea about the treatment technologies implemented worldwide.
