Although bioremediation is considered the most environmentally friendly and sustainable technique for remediating contaminated soil water, it effective when combined with physicochemical methods, which allow preliminary removal of large quantities pollutants. This allows microorganisms to efficiently eliminate remaining contaminants. In addition requiring necessary genes degradation pathways specific substrates, as well tolerance adverse environmental conditions, may perform below expectations. One typical reason this high toxicity xenobiotics present in concentrations, stemming from vulnerability bacteria introduced a site. especially true planktonic bacteria, whereas within biofilms or microcolonies have significant advantages over their counterparts. A physical matrix essential formation, maintenance, survival bacterial biofilms. By providing such immobilization, formation can be facilitated accelerated. Therefore, immobilization offers comprehensive solution cleanup by harnessing specialized metabolic activities while ensuring retention efficacy at target sites. many cases, also need methods that are otherwise required initially reduce contaminant concentrations. Then, will possible use remediation higher concentrations xenobiotics, significantly reducing costs maintaining rapid rate processes. review explores benefits highlighting materials processes developing an optimal matrix. It focuses on following four key areas: (i) types organic pollutants impacting human health, (ii) strains used processes, (iii) (iv) cells various carriers targeted pollutant degradation.

One of the challenges researchers have to deal with is achieving a high surface area for biofilm plastic media used in wastewater treatment. This study evaluates bioball reactors using two different configurations (modified and conventional bioballs). It performance each configuration based on biochemical oxygen demand (BOD), chemical (COD), total suspended solid (TSS) while monitoring pH, temperature, DO during 36-day operation time. The lab-scale rector consists 1m3 feeding tank, 100 L aeration settling tank two-hour retention time operated real domestic wastewater. removal efficiency all parameters shows that modified reactor better organic matter (7% BOD removal, 6% COD, 4% TSS removal). In summary, has promising potential facilitate construction compact treatment plants or modernize poor-performing plants.

Treatment Performance and Characteristics of Biofilm Carriers in an Aerobic Waterwheel-Driven Rotating Biological Contactor

Water, Год журнала: 2025, Номер 17(3), С. 356 - 356

Опубликована: Янв. 27, 2025

Rotating biological contactors (RBCs) are widely utilized in aerobic wastewater treatment due to their high stability, efficiency, and ease of maintenance. The choice disc carrier material for biofilm formation is a critical factor influencing performance. In the context rural domestic treatment, carriers must balance cost-effectiveness efficiency. This study focuses on unit combined anoxic denitrification–deodorization filter–aerobic RBC system, specifically, waterwheel-driven RBC, evaluates three types media: felt, carbon nonwoven fabric. compares pollutant removal performance enrichment characteristics identify optimal material. results indicate that RBCs using fabric as exhibit superior nitrification efficiency biocompatibility compared other materials, achieving average rates 84.3% CODCr 80.5% ammonia nitrogen. While addition slightly reduced driving it significantly enhanced oxygen transfer which explained organic degradation nitrification. During stable phase, two-stage with achieved nitrogen 86.76 ± 0.85% 92.15 1.49%, respectively. Nonwoven demonstrates significant potential rotating contactors.

Anaerobic Bioremediation of Acid Mine Drainage Using Sulphate-Reducing Bacteria: Current Status, Challenges, and Future Directions

Sustainability, Год журнала: 2025, Номер 17(8), С. 3567 - 3567

Опубликована: Апрель 15, 2025

Biological reduction of sulphates has gradually replaced unit chemical processes for the treatment acid mine drainage (AMD), which exerts a significant environmental impact due to its elevated acidity and high concentrations heavy metals. Bioremediation is optimally suited AMD because it cost-effective efficient. Anaerobic bioremediation employing sulphate-reducing bacteria (SRB) presents promising solution by facilitating sulphate sulphide. The formed can precipitate immobilise metals, assisting them in their removal from contaminated wastewater. This paper examines current status SRB-based bioremediation, with an emphasis on recent advances microbial processes, reactor design, efficiencies. Reviewed studies showed that bioreactors achieve up 93.97% reduction, metal recovery rates 95% nickel, 98% iron copper, 99% zinc under optimised conditions. Furthermore, used glycerol ethanol as carbon source improved efficiency achieving pH neutralisation 2.8 7.5 within 14 days hydraulic retention time. Despite results achieved so far, several challenges remain. These include need optimal conditions, management toxic hydrogen sulphide production, economic feasibility large-scale applications. Future directions are proposed address these challenges, focusing genetic engineering SRB, integration other technologies, development sustainable strategies. Ultimately, this review provides valuable information improve scalability remediation methods, contributing more mining practices conservation. To ensure relevance credibility, regency were criteria literature search. sourced directly related subject review, latest research, typically last 5 10 years, was prioritised.
