“…Renuka, Sood, Ratha, et al () found that an algae consortium reduced TDS by 28% (from 1,120 to 806 mg/L). More than 50% reduction of TDS from mixed industrial wastewaters was reported with the consortium of Chlorella and Phormidium after 20 days of incubation (Das, Ramaiah, Pereira, & Naseera, ), while even higher TDS removal efficiency (65%–80%) was reported in industrial wastewaters (Khan et al, ), oil and gas production wastewater (Lutzu & Dunford, ), and distiller wastewater (Krishnamoorthy et al, ). From a percentage perspective, the TDS removal efficiency reported in this work (TDS‐E [%], Table ), particularly for the BC reactor, was in the lower end compared to the date reported in previous research.…”

“…In this work, the BC and RAB reactors were based on the continuous culture resulting in a much higher volumetric removal rate (i.e., TDS‐R volume [mg/L‐day], Table ). For example, the BC reactor removed TDS at a rate of 21–121 mg/L‐day (Table ) and the RAB system removed at 101–2,783 mg/L‐day, while the TDS removal rates of the previous reports were calculated as 9 mg/L‐day (Maity et al, ), 25 mg/L‐day (El‐Bestawy, ), 45 mg/L‐day (Renuka, Sood, Ratha, et al, ), 130 mg/L‐day (Das et al, ), 349 mg/L‐day (Lutzu & Dunford, ), 9–30 mg/L‐day (Khan et al, ), and 4 mg/L‐day (Krishnamoorthy et al, ). With the further process optimization such as light intensity, TDS removal efficiency by the RAB and BC reactors can be further increased.…”

“…Compared to the existing methods, biological absorption by microalgae is a mild and environmental friendly method for TDS removal. Algal cells absorb TDS species as nutrients and minerals to support their physiology and metabolisms while reducing TDS in water (Cho, Luong, Lee, Oh, & Lee, ; Khan, Shamshad, Waqas, Nawab, & Ming, ; Krishnamoorthy, Manickam, & Muthukaruppan, ; Lutzu & Dunford, ; Renuka, Sood, Ratha, Prasanna, & Ahluwalia, ; Sydney et al, ; Zhou, Li, et al, ). A consortium of filamentous algae was reported to reduce TDS of sewage water from 1,120 to 806 mg/L over 6 days (Renuka, Sood, Ratha, Prasanna, & Ahluwalia, ).…”

“…In oil and gas production wastewater treatment, algae can remove up to 65% TDS over 30 days (Lutzu & Dunford, ). Krishnamoorthy et al () used blue‐green algae to treat distiller wastewater with 64%–80% TDS removal over 7 days.…”

Total dissolved solids (TDS) comprising inorganic salts and organic matters are pollutants of concern to aquatic systems and water for human use. This work aimed to investigate the use of revolving algal biofilm (RAB) reactors as a sustainable and environmental friendly method to remove TDS from industrial effluents and municipal wastewaters. The wastewaters contained chloride, sodium, potassium, calcium, magnesium, and sulfate as the major components. The RAB reactors fed with synthetic industrial effluent with high TDS level demonstrated the best algal growth, with the highest TDS removal efficiency (27%) and removal rate (2,783 mg/L-day and 19,530 mg/m 2 -day). A suspended algal culture system only removed 3% TDS from the same wastewater. The TDS removal by the RAB reactors was considered due to several mechanisms such as absorption by the algae cells, adsorption by extracellular polymeric substance of the biofilm, and/or precipitation. Collectively, this research shows that the RAB reactors can serve as an efficient system in wastewater remediation for TDS removal. © 2019 Water Environment Federation • Practitioner points• Total dissolved solids (TDS) in wastewater are pollutants of concern. • The RAB reactors can remove TDS from various types of wastewater. • The RAB reactors removed TDS by adsorbing ions elements such as Cl, Na, K, Ca, Mg, and S. • The algal biomass absorbs ions through extracellular polymeric substance.

“…Apart from physico-chemical processes of stillage treatment, the use of microalgae seems to be a method that will be developed in the future [92]. This is because microalgae can use waste as a source of nutrients and their by-products can be processed into alcohol, aquaculture feed, poultry feed, and organic fertilizers, thus reducing the total cost of treatment [93,94].…”

Distilleries are among the most polluting industries because ethanol fermentation results in the discharge of large quantities of high-strength liquid effluents with high concentrations of organic matter and nitrogen compounds, low pH, high temperature, dark brown color, and high salinity. The most common method of managing this wastewater (distillery stillage) is to use it for soil conditioning, but this requires thickening the wastewater and may cause soil pollution due to its high nitrogen content. Therefore, treatment of distillery stillage is preferable. This review discusses individual biological and physico-chemical treatment methods and combined technologies. In addition, special attention is paid to valorization of distillery stillage, which is a valuable source of polysaccharides and volatile fatty acids (VFAs), as well as natural antioxidants, including polyphenols and other bioactive compounds of interest to the pharmaceutical, cosmetic, and food industries. New directions in improvement of valorization technologies are highlighted, including the search for new eutectic solvents for extracting these compounds. Such technologies are essential for sustainable development, which requires the use of management and valorization strategies for recovery of valuable compounds with minimal disposal of waste streams.

Current global environmental issues raise unavoidable challenges for our use of natural resources. Supplying the human population with clean water is becoming a global problem. Numerous organic and inorganic impurities in municipal, industrial, and agricultural waters, ranging from microplastics to high nutrient loads and heavy metals, endanger our nutrition and health. The development of efficient wastewater treatment technologies and circular economic approaches is thus becoming increasingly important. The biomass production of microalgae using industrial wastewater offers the possibility of recycling industrial residues to create new sources of raw materials for energy and material use. This review discusses algae‐based wastewater treatment technologies with a special focus on industrial wastewater sources, the potential of non‐conventional extremophilic (thermophilic, acidophilic, and psychrophilic) microalgae, and industrial algae‐wastewater treatment concepts that have already been put into practice.
