The rapid expansion of both the global economy and human population has led to a shortage water resources suitable for direct consumption. As result, remediation will inexorably become primary focus on scale. Microalgae can be grown in various types wastewaters (WW). They have high potential remove contaminants from effluents industries urban areas. This review focuses recent advances WW through microalgae cultivation. Attention already been paid microalgae-based wastewater treatment (WWT) due its low energy requirements, strong ability thrive under diverse environmental conditions, transform nutrients into high-value compounds. It turned out that WWT is an economical sustainable solution. Moreover, different toxins are removed by biosorption, bioaccumulation, biodegradation processes. Examples agricultural runoffs textile pharmaceutical industrial effluents. mitigate carbon dioxide make use micronutrients present paper highlights application pollutants commonly mechanisms, simultaneous resource recovery, efficient co-culturing systems along with bottlenecks prospects.

Enhanced microalgal lipid production for biofuel using different strategies including genetic modification of microalgae: A review

Progress in Energy and Combustion Science, Journal Year: 2023, Volume and Issue: 96, P. 101071 - 101071

Published: Feb. 27, 2023

Microalgae have gained considerable attention as an alternative feedstock for the biofuel production, particularly in combination with genetic modification strategies that target enhanced lipid productivity. To tackle climate change issues, phasing out usage of fossil fuels is seen a priority, where utilization from microalgae serves potential sustainable energy source various applications. These photosynthetic utilize solar and carbon dioxide to produce energy-rich compounds (i.e., starch lipids), can be further converted into biofuels different types. Among types biofuels, biodiesel transesterification triacylglycerols stands most replacement transportation fuel over fossil-based petroleum diesel. However, hurdles such limited productivity, overall production cost challenges upscaling algal technology leaves huge gap on road commercialized microalgae-based biofuel. This review article first presents comprehensive overview imperative knowledge regarding terms classification, factors affecting growth during cultivation steps upstream processing. also discusses recent advances downstream processing microalgal biorefinery. Additionally, this paper focuses deliberating modifications their feasibility productivity microalgae. Finally, current future perspectives are highlighted discussing several aspects, including sustainability status algae-based industry, risks legislation considerations

Methods to prepare biosorbents and magnetic sorbents for water treatment: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(4), P. 2337 - 2398

Published: May 4, 2023

Access to drinkable water is becoming more and challenging due worldwide pollution the cost of treatments. Water wastewater treatment by adsorption on solid materials usually cheap effective in removing contaminants, yet classical adsorbents are not sustainable because they derived from fossil fuels, can induce secondary pollution. Therefore, biological sorbents made modern biomass increasingly studied as promising alternatives. Indeed, such biosorbents utilize waste that would otherwise pollute systems, promote circular economy. Here we review biosorbents, magnetic sorbents, other cost-effective with emphasis preparation methods, types, mechanisms, regeneration spent adsorbents. Biosorbents prepared a wide range materials, including wood, bacteria, algae, herbaceous agricultural waste, animal waste. Commonly removed contaminants comprise dyes, heavy metals, radionuclides, pharmaceuticals, personal care products. Preparation methods include coprecipitation, thermal decomposition, microwave irradiation, chemical reduction, micro-emulsion, arc discharge. Adsorbents be classified into activated carbon, biochar, lignocellulosic clays, zeolites, peat, humic soils. We detail isotherms kinetics. Regeneration supercritical fluid desorption. also discuss exhausted adsorbent management disposal. found agro-waste remove up 68–100% while wooden, herbaceous, bacterial, marine-based 55–99% metals. Animal waste-based 1–99% The average removal efficiency modified around 90–95%, but some treatments, cross-linked beads, may negatively affect their efficiency.
