“…Wastewater could contain several compounds at elevated concentrations that inhibit biological (e.g., microalgal) growth [25]. Similarly, the turbidity and pH of wastewater could inhibit microalgal growth [26]. Physicochemical pretreatment of wastewater would improve the conditions for microalgal growth and reduce wastewater's strength [27,28].…”

“…While the produced water could be toxic to many microalgal strains, some algal strains (e.g., Chlorella sp., Dunaliella sp., Scenedesmus sp., etc.) could tolerate and grow in the produced or pretreated produced water [26,101,102]. The algae-bacterial consortium could effectively treat the produced water [26,101,103].…”

“…could tolerate and grow in the produced or pretreated produced water [26,101,102]. The algae-bacterial consortium could effectively treat the produced water [26,101,103]. The feasibility of large-scale microalgal biomass production in several countries, using produced water, was recently explored [17].…”

“…As the microalgae grow in wastewater, they would consume the nutrients and concentrate other contaminants in wastewater. Depending on the biomass harvesting technique, the microalgal biomass could also be contaminated with other unwanted compounds [26], which could interfere with the intended use of the produced biomass. Therefore, the removal of the coagulants would be necessary for specific applications.…”

“…In some wastewaters, nitrogen could be present in aromatic compounds as nitro, amino, or other groups. If the pH value of wastewater is either very low or very high, then it should be adjusted in the appropriate range for efficient microalgal bioremediation [26]. The concentration of nitrogen and or phosphorus in wastewater could be low in wastewater, which would yield a low biomass density; the cost and energy requirement per unit of biomass separation could be very high-rendering the overall process of microalgal bioremediation nonviable.…”

The treatment of different types of wastewater by physicochemical or biological (non-microalgal) methods could often be either inefficient or energy-intensive. Microalgae are ubiquitous microscopic organisms, which thrive in water bodies that contain the necessary nutrients. Wastewaters are typically contaminated with nitrogen, phosphorus, and other trace elements, which microalgae require for their cell growth. In addition, most of the microalgae are photosynthetic in nature, and these organisms do not require an organic source for their proliferation, although some strains could utilize organics both in the presence and absence of light. Therefore, microalgal bioremediation could be integrated with existing treatment methods or adopted as the single biological method for efficiently treating wastewater. This review paper summarized the mechanisms of pollutants removal by microalgae, microalgal bioremediation potential of different types of wastewaters, the potential application of wastewater-grown microalgal biomass, existing challenges, and the future direction of microalgal application in wastewater treatment.

Rapid industrialization is one of the intricate factors that is linked to the depletion of water resources and increased generation of wastewater. Due to various obstructions and impediments, such as ineffective treatment solutions, exorbitant prices, lack of basic amenities, insufficient financial assistance, and technical expertise, sustainable treatment of industrial effluents has become an onerous process in most parts of the world. The majority of current treatment solutions are conventional and outdated, and thus fall short to remove all the contaminants efficiently from the industrial wastewater. Moreover, poorly treated or untreated industrial effluents are indiscriminately dumped into water bodies such as lakes, ponds, and rivers, causing substantial health hazards to humans and animals and serious threats to the aquatic ecosystem. Thus, there is a need for highly efficient, cost-effective, and sustainable technologies for the treatment of industrial wastewater. Employment of microbial technologies such as microbial fuel cells and microalgal technologies, treatment of wastewater can be coupled with the production of bioelectricity and valuable biomass, respectively. Moreover, with nanofiltration and biochar technologies, the efficiency of the overall treatment procedure can be increased to a greater extent. The present review aims to highlight opportunities and challenges associated with some of the emerging trends in industrial wastewater research.
