HIGHLIGHTS

  • Aged refuse-based bioreactor (ARB) is widely used in wastewater treatment.
  • Review on pollutant removal efficiencies in wastewater using ARB.
  • Wastewaters from different sources treated by ARB are discussed.
  • Factors affecting the pollutants removal in ARB operation are focused.
  • It provides a sustainable approach to treat various wastewaters & leachate.

ABSTRACT

Municipal landfilling has remained the universal method for solid waste disposal; however, its limitation is the generation of landfill leachate, which is a major environmental issue. The aged refuse-based bioreactor/biofilter (ARB) can remove numerous pollutants from various wastewaters using the principle of waste control by waste. It can remove organic pollutants also. Wastewater treatment by ARBs has been proved to be technically practicable, environmental friendly, economically favorable and simple to operate than other conventional biological methods. Researchers have carried out diverse studies centered on operational and environmental factors including temperatures, loading rates, height of aged refuse, and aerobic or anaerobic conditions. To this end, this article takes an overview of significant pollutant removal efficiencies using ARB in wastewater treatment, highlighting particularly landfill leachate, sewage and livestock wastewater. As the construction of new landfills is not an easy task, it is rather practicable to reclaim and excavate aged refuse from landfills in order to utilize it and at the same time to provide more space for new waste at site.
