Water crisis around the world leads to a growing interest in emerging contaminants (ECs) that can affect human health and environment. Research showed thousands of compounds from domestic consumers, such as endocrine disrupting chemicals (EDCs), personal care products (PCPs), pharmaceuticals active (PhAcs), could be found wastewater concentration mostly ng L−1 μg L−1. However, generally, treatment plants (WWTPs) are not designed remove these ECs their discharge levels. Scientists looking for economically feasible biotreatment options enabling complete removal before discharge. Microalgae cultivation is likely approach removing simultaneously any residual organic nutrients. Microalgal growth rate efficiency affected by various factors, including light intensity, CO2 addition, presence different nutrients, etc., parameters greatly help make microalgae more efficient. Furthermore, algal biomass harvests repurposed produce bulk sustainable aviation fuel, biofuel, bioplastic, biochar; this significantly enhance economic viability. Therefore, review summarizes microalgae-based bioprocess mechanisms wastewaters highlights strategies improve efficiency. shows role profile relevance using ECs-treated green products, well challenges future research recommendations.

Microalgae-based bioremediation of refractory pollutants: an approach towards environmental sustainability

Microbial Cell Factories, Год журнала: 2025, Номер 24(1)

Опубликована: Янв. 14, 2025

Abstract Extensive anthropogenic activity has led to the accumulation of organic and inorganic contaminants in diverse ecosystems, which presents significant challenges for environment its inhabitants. Utilizing microalgae as a bioremediation tool can present potential solution these challenges. Microalgae have gained attention promising biotechnological detoxifying environmental pollutants. This is due their advantages, such rapid growth rate, cost-effectiveness, high oil-rich biomass production, ease implementation. Moreover, microalgae-based remediation more environmentally sustainable not generating additional waste sludge, capturing atmospheric CO 2 , being efficient nutrient recycling algal production biofuels high-value-added products generation. Hence, achieve sustainability's three main pillars (environmental, economic, social). Microalgal mediate contaminated wastewater effectively through accumulation, adsorption, metabolism. These mechanisms enable reduce concentration heavy metals levels that are considered non-toxic. However, several factors, microalgal strain, cultivation technique, type pollutants, limit understanding removal mechanism efficiency. Furthermore, adopting novel technological advancements (e.g., nanotechnology) may serve viable approach address challenge refractory pollutants process sustainability. Therefore, this review discusses ability different species mitigate persistent industrial effluents, dyes, pesticides, pharmaceuticals. Also, paper provided insight into nanomaterials, nanoparticles, nanoparticle-based biosensors from immobilization on nanomaterials enhance open new avenue future advancing research regarding biodegradation

Emerging Pollutants in Wastewater, Advanced Oxidation Processes as an Alternative Treatment and Perspectives

Processes, Год журнала: 2022, Номер 10(5), С. 1041 - 1041

Опубликована: Май 23, 2022

Emerging pollutants are present in wastewaters treated by conventional processes. Due to water cycle interactions, these contaminants have been reported groundwater, surface water, and drinking waters. Since processes cannot guarantee their removal or biotransformation, it is necessary study that comply with complete elimination. The current literature review was conducted describe provide an overview of the available information about most significant groups emerging could potentially be found wastewater environment. In addition, describes main entry distribution pathways into environment through cycle, as well some potential effects they may cause flora, fauna, humans. Relevant on SARS-CoV-2 virus its spread included. Furthermore, also outlines Advanced Oxidation Processes (AOPs) used for total partial removal, emphasizing reaction mechanisms process parameters need considered. As well, biological that, although slow, effective biotransformation can combination advanced oxidation
