Desalination brine discharge has several negative impacts on the marine environment, such as increase in salinity levels, effects biodiversity, and alteration of physical chemical characteristics water. In addition, desalination plants consume significant amounts energy, which contribute to carbon emissions global warming. Various management strategies have been adopted mitigate discharge, these are often expensive, require extensive infrastructure, may not be feasible all locations. The focus this review is Algae-based bioremediation, a promising approach managing it only reduces environmental pollution but also produces valuable biomass products. Mechanisms employed by microalgae for including nutrient recovery, organic heavy metal removal through processes like biosorption, bioaccumulation, detoxification discussed. Algae can grow high water use nutrients present produce biomass, harvested used variety applications, biofuels, feed, pharmaceuticals. This potentially provide sustainable cost-effective solution from plants. highlights achievements microalgae-based remediation, sequestration valorization microalgal after treatment. Challenges field, brine's algal harvesting, addressed. paper outlines research trends that encompass strain selection optimization, capture, recycling, photobioreactor design, anaerobic digestion, biochar production, techno-economic feasibility analysis. These future-focused approaches aim enhance sustainability efficacy cultivation remediation.

Bioresource Technology, Год журнала: 2024, Номер 406, С. 131022 - 131022

Опубликована: Июнь 22, 2024

Membrane bioreactors (MBRs) hold significant promise for wastewater treatment, yet the persistent challenge of membrane fouling impedes their practical application. One promising solution lies in synergy between microalgae and bacteria, offering efficient nutrient removal, reduced energy consumption, potential mitigation extracellular polymeric substances (EPS) concentrations. Inoculating presents a avenue to address MBRs. This review marks first exploration utilizing control MBR systems. The begins with comprehensive overview evolution distinctive traits microalgae-MBRs. It goes further insight into performance underlying mechanisms facilitating reduction through intervention. Moreover, not only identifies challenges inherent employing MBRs but also illuminates prospective pathways future advancement this burgeoning field.

Abstract Dealing with membrane fouling poses multiple difficulties. Conventional cleaning techniques, such as backwashing and chemical cleaning, are frequently inadequate in effectively dealing various types of can result the gradual deterioration membrane. Advanced technologies ozone treatment advanced oxidation processes present interesting answers, but they necessitate meticulous optimisation incur significant costs. It is crucial to develop materials that resistant create monitoring control systems operate real-time order enhance management. essential overcome these problems improve performance, cost-effectiveness, sustainability membrane-based water used production drinking water. This paper overviews role ozonation when it coupled process. In general, pretreatment and/or post its mechanism mitigation, investigation elimination natural organic matter (NOM) bio-toxicity process, prospect be mitigation process for potable reuse.
