“…Bioreactors are enclosed vessels where biological reactions take place and they have been identified as one of the most remarkable technologies for the treatment of a variety of wastewaters ( Mishra et al, 2022 ). Within these vessels, microorganisms such as bacteria, fungi, or algae, consume and degrade the toxic pollutants in the effluent, converting them into less harmful derivatives and sometimes basic compounds such as carbon dioxide and water ( Khalidi-idrissi et al, 2023 ). Bioreactors have been noted to have various advantages over conventional methods of removing PhACs as they create less sludge, have lower energy demand and typically emit lower amounts of greenhouse gases ( Dos Santos et al, 2022 ).…”

For instance, cross-linked enzymes aggregates of laccase and polysulfone hollow fiber membrane was developed for the elimination of acetaminophen, carbamazepine and mefenamic acid ( Ba et al, 2014 ).…”

The ability of fungal species to produce a wide range of enzymes and metabolites, which act synergistically, makes them valuable tools in bioremediation, especially in the removal of pharmaceutically active compounds (PhACs) from contaminated environments. PhACs are compounds that have been specifically designed to treat or alter animal physiological conditions and they include antibiotics, analgesics, hormones, and steroids. Their detrimental effects on all life forms have become a source of public outcry due their persistent nature and their uncontrolled discharge into various wastewater effluents, hospital effluents, and surface waters. Studies have however shown that fungi have the necessary metabolic machinery to degrade PhACs in complex environments, such as soil and water, in addition they can be utilized in bioreactor systems to remove PhACs. In this regard, this review highlights fungal species with immense potential in the biodegradation of PhACs, their enzymatic arsenal as well as the probable mechanism of biodegradation. The challenges encumbering the real-time application of this promising bioremediative approach are also highlighted, as well as the areas of improvement and future perspective. In all, this paper points researchers to the fact that fungal bioremediation is a promising strategy for addressing the growing issue of pharmaceutical contamination in the environment and can help to mitigate the negative impacts on ecosystems and human health.

“…Treatment options include neutralization to raise pH, precipitation, and flocculation to remove heavy metals and other pollutants, and biological treatment to remove organic pollutants. The specific treatment options depend on the type and concentration of contaminants present in the process water [ 59 ]. It is also important to know that regulations for the treatment and discharge of industrial process water vary by region and industry.…”

In 2022, Poland and Germany experienced a prolonged and extensive mass fish kill in the Odra River. During the period from the end of July to the beginning of September 2022, a high level of incidental disease and mortality was observed in various fish species (dozens of different species were found dead). The fish mortality affected five Polish provinces (Silesia, Opole, Lower Silesia, Lubuskie, and Western Pomerania) and involved reservoir systems covering most of the river (the Odra River is 854 km long, of which 742 km are in Poland). Fatal cases were investigated using toxicological, anatomopathological, and histopathological tests. Water samples were collected to determine nutrient status in the water column, phytoplankton biomass, and community composition. High nutrient concentrations indicated high phytoplankton productivity, with favorable conditions for golden algal blooms. The harmful toxins (prymnesins secreted by Prymnesium parvum habitats) had not been found in Poland before, but it was only a matter of time, especially in the Odra River, whose waters are permanently saline and still used for navigation. The observed fish mortality resulted in a 50% decrease in the fish population in the river and affected mainly cold-blooded species. Histopathological examinations of fish showed acute damage to the most perfused organs (gills, spleen, kidneys). The disruption to hematopoietic processes and damage to the gills were due to the action of hemolytic toxins (prymnesins). An evaluation of the collected hydrological, meteorological, biological, and physico-chemical data on the observed spatio-temporal course of the catastrophe, as well as the detection of three compounds from the group of B-type prymnesins in the analyzed material (the presence of prymnesins was confirmed using an analysis of the fragmentation spectrum and the accurate tandem mass spectrometry (MS/MS) measurement, in combination with high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS), allowed the formulation and subsequent testing of the hypothesis for a direct link between the observed fish mortality and the presence of prymnesins in the Odra River. This article systematizes what is known about the causes of the fish kill in the Odra River in 2022, based on official government reports (one Polish and one German) and the EU technical report by the Joint Research Centre. A review and critical analysis of government findings (Polish and German) on this disaster were conducted in the context of what is known to date about similar cases of mass fish kills.

“…Prominently, the achievement of high COD reductions above 90% with technologies such as extended aeration and the addition of activated carbon medium, Biocord-IFAS, fourstage SBRs, chemical activation of dye sludge and biofilm processes like moving bed biofilm reactors (Jagaba, Kutty, Noor et al, 2022;Khalidi-Idrissi et al, 2023;Meena et al, 2022;Thi Tuyet Nhi et al, 2022). Many conventional activated sludge plants also realized removals in the 75-85% band.…”

“…Various practices have been reconnoitered for COD removal embracing physicalchemical methods, advanced oxidation processes and biological treatments such as activated sludge, moving bed biofilm reactor (MBBR), sequencing batch reactor (SBR), membrane bioreactor, and ozonation (Khalidi-Idrissi et al, 2023;Meena et al, 2022). Among them, activated sludge process is more efficient, relatively low operation costs, simple process, and able to treat varied industrial wastewaters (Jagaba, Kutty, Baloo, et al, 2022;Jagaba, Kutty, Noor, et al, 2022;Khalidi-Idrissi et al, 2023;Meena et al, 2022;Mirbolooki et al, 2017). It employs microorganisms grow as bacterial flocs in an aeration tank to biologically degrade organic matter when sufficient oxygen is provided (Seviour and Nielsen, 2010;Shchegolkova et al, 2016).…”

<p>This study investigated aerobically COD removal and microbial dynamics during activated sludge treatment of wastewater. The 12-day experiment utilized descriptive analysis to correlate operational parameters of pH, F/M ratio, MLSS, and SVI with COD removal efficiency. Microscopic examination identified temporal shifts in abundances of bacterial flocs, flagellates, ciliates, and rotifers. COD removal declined from 79% on day 0 to 4% by day 12, corresponding with increased SVI and protozoan proliferation. High SVI caused biomass washout, reducing bacterial catabolic capacity. Predominance of bacterivorous protozoa and rotifers likely suppressed floc-forming bacteria responsible for COD biodegradation. Conserving balanced mixed communities through optimized operational conditions appears decisive for continuous treatment performance. This study provides comprehensions on microbial ecological interactions altering temporal variability in activated sludge COD removal.</p>
