Special Issue Information

Dear Colleagues,

Biological treatment is typically applied for wastewater remediation due to the advantages of high efficiency and low cost. Its main principle is to degrade or transform the organic, inorganic and micropollutants in wastewater through the metabolism of microorganisms. In recent years, sustainable biological treatment technologies (e.g., anaerobic digestion, anammox, microbial fuel cells, etc.) have been also successfully developed to reduce operational costs or recover resources from wastewater. For both traditional and sustainable wastewater systems, the function of biological control plays a significant role by affecting the microbial activity and abundance. Appropriate biological control parameters and strategies can help to obtain higher operating efficiency, lower energy and more products.

This Special Issue will concentrate on highlighting timely research studies that address the function of biological control in wastewater management and resource recovery. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Biological control and mechanisms in traditional or sustainable wastewater systems;
  • Achievement and application of sustainable biological wastewater treatments;
  • Production and characterization of microbial metabolites in wastewater management;
  • Biological control in the treatment of constructed wetlands;
  • Function of biological control in resource and energy recoveries from wastewater;
  • Biological resource utilization technology in wastewater.

We look forward to receiving your contributions.

Sewage sludge is a useful raw material for the production of renewable energy due to its stable annual output. In this study, the enhancement of mesophilic anaerobic digestion of sewage sludge through heat pretreatment at 95 °C for 30 min was tested in an anaerobic moving bed biofilm reactor (hAMBBR). The sludge retention time was set at 20, 15, 10, and 5 days during 300 days of operation and compared to a traditional anaerobic continuous stirred tank reactor (AnCSTR) without pretreatment. Results of this research indicate that the digestion ratio of volatile soluble solids in the hAMBBR process could be improved by 50%, and the average conversion ratio of methane could be increased by 45%. When the sludge retention time (SRT) was shortened to 5 days, the methane production approached twice that of the contrast reactor. The expanded anaerobic digestion model, including activated sludge models, was utilized for operation simulation. The effect of sludge retention time (SRT) shortening on volatile suspended solids (VSS) digestibility and methane production was well reproduced with simulations. The research conclusion reveals the impact of pretreatment and reactor types on anaerobic digestion and provides the scientific basis for improving methane production and process efficiency in anaerobic digestion.
