Post technological advancements and industrialisation, the recovery of resources by treating wastewater is gaining momentum. As the global population continues to grow, the need for water is becoming increasingly urgent. Therefore, the re‐utilisation of water is becoming an increasingly important factor in the preservation of life on this planet. Wastewater is classified according to its source of origin. When left untreated, the effluent causes several environmental hazards and poses health issues as they have higher concentrations of nutrients and toxic heavy metals. Currently, several conventional methods exist to treat and handle wastewater, but they generate secondary waste post‐treatment and are not sustainable. Microalgae‐based treatment of wastewater is highly sustainable, cost‐efficient and aligns with the concept of circular bioeconomy. The biological treatment of effluents using microalgae has several advantages. Approximately 1.83 kg of CO2 is sequestered per kg of the dry biomass during microalgae cultivation. Among all the sustainable alternatives, microalgae offer better biomass productivity by utilising a higher concentration of nutrients in wastewater. The wastewater‐grown microalgae have higher efficiency in producing commercially important secondary metabolites. This systematic review highlights the competence of microalgae in different wastewater sources and their industrial perspectives. This also gives an overview of the biproducts produced from microalgae‐based wastewater treatment.

The scarcity of water resources and environmental pollution have highlighted the need for sustainable wastewater treatment. Existing conventional treatment systems are energy-intensive and not always able to meet stringent disposal standards. Recently, algal-bacterial systems have emerged as environmentally friendly sustainable processes for wastewater treatment and resource recovery. The algal-bacterial systems work on the principle of the symbiotic relationship between algae and bacteria. This paper comprehensively discusses the most recent studies on algal-bacterial systems for wastewater treatment, factors affecting the treatment, and aspects of resource recovery from the biomass. The algal-bacterial interaction includes cell-to-cell communication, substrate exchange, and horizontal gene transfer. The quorum sensing (QS) molecules and their effects on algal–bacterial interactions are briefly discussed. The effect of the factors such as pH, temperature, C/N/P ratio, light intensity, and external aeration on the algal-bacterial systems have been discussed. An overview of the modeling aspects of algal-bacterial systems has been provided. The algal-bacterial systems have the potential for removing micropollutants because of the diverse possible interactions between algae-bacteria. The removal mechanisms of micropollutants – sorption, biodegradation, and photodegradation, have been reviewed. The harvesting methods and resource recovery aspects have been presented. The major challenges associated with algal-bacterial systems for real scale implementation and future perspectives have been discussed. Integrating wastewater treatment with the algal biorefinery concept reduces the overall waste component in a wastewater treatment system by converting the biomass into a useful product, resulting in a sustainable system that contributes to the circular bioeconomy.

“…To the best of our knowledge, this is the first study in which the above-mentioned species have been associated to degradation of micropollutants, except for Klebsiella spp, which has previously been associated with the degradation of aromatic compounds. The facultatively anaerobic Klebsiella genus (Enterobacterceae family) has been related to the degradation of linear alkylbenzene sulfonate (LAS) (Pandey et al, 2020), polycycli aromatic hydrocarbons (Xu et al, 2019), anti-inflammatory drug diclofenac sodium (Sharma et al, 2021), and aliphatic and aromatic hydrocarbons from crude oil (Chamkha et al, 2011). Like Phytobacter spp, these organisms also possess nitrification and denitrification properties.…”
