Abstract Background Water contamination has become one of the most challenging problems to clean water supply and infrastructure in twenty-first century. Accordingly, access is limited by negative impacts climate change pollutants varying health risks. Overtime, global population experienced an exponential growth, which put pressure on resources. At least 3 billion people globally rely whose quality largely unknown.

A significant concentration of pharmaceuticals has been detected within composted sewage sludge. Their uncomplete removal and lack monitoring during composting neglects their potentially toxic effects when used as a soil organic amendment. Previously, we successfully implemented bioaugmentation–composting system focused on toxicity pharmaceuticals’ reduction. This method, however, comprised long inoculant-acclimatization period, making it an unprofitable technology. Hence, this work aimed to explore shorter yet effective process by simultaneously implementing the inoculation native microbial consortium fungus Penicillium oxalicum XD 3.1 in piles sludge olive prunings. All were subjected frequent inoculation, windrow turning, physicochemical biological parameters. Additionally, both bioaugmentation stability degradation evaluated through different analysis rates calculations. One hundred days earlier than previous attempts, treatments achieved adequate conditions, maintained core populations while improving degrading diversity, around 70–72% pharmaceutical remotion. Nevertheless, only produced favorable results ideal for amendments (acute microtoxicity phytotoxicity). Thus, but equally stable with P. was here.

This review aims to assess different technologies for the on-site treatment of hospital wastewater (HWW) remove pharmaceutical compounds (PhCs) as sustances emerging concern at a bench, pilot, and full scales from 2014 2020. Moreover, rough characterisation effluents is presented. The main detected PhCs are antibiotics psychiatric drugs, with concentrations up 1.1 mg/L. On one hand, regarding presented technologies, membrane bioreactors (MBRs) good alternative treating HWW removal values higher than 80% in removing analgesics, anti-inflammatories, cardiovascular some antibiotics. this system has been scaled pilot plant scale. However, target still present treated effluent, such contrast media drugs recalcitrant (erythromycin sulfamethoxazole). other ozonation effectively removes found (>93%), studies carried out Even though, families, X-ray media, ozone. Other advanced oxidation processes (AOPs), Fenton-like or UV treatments, seem very effective pharmaceuticals, Antibiotic Resistance Bacteria (ARBs) Genes (ARGs). they not implanted scale usually consider extra reactants ozone, iron, UV-light, making scale-up challenging task treat high-loading wastewater. Thus, several examples biological methods combined AOPs have proposed better strategy high (generally over 98%) ARGs/ARBs (below detection limit) lower spending on reactants. it requires further development optimisation integrated processes.

Municipal wastewaters can generally provide real-time information on drug consumption, the incidence of specific diseases, or establish exposure to certain agents and determine some lifestyle consequences. From this point view, wastewater-based epidemiology represents a modern diagnostic tool for describing health status part population in region. Hospital wastewater is complex mixture pharmaceuticals, illegal drugs, their metabolites as well different susceptible antibiotic-resistant microorganisms, including viruses. Many studies pointed out that from healthcare facilities (including hospital wastewater), significantly contributes higher loads micropollutants, bacteria viruses, municipal wastewater. In addition, such increase selective pressure bacteria, thus contributing development dissemination antimicrobial resistance. Because many microorganisms pass through treatment plants without any significant change structure toxicity enter surface waters, technologies need be improved. This short review summarizes recent knowledge pathogens, viruses SARS-CoV-2) facilities. It also proposes several possibilities improving process terms efficiency economy.

Antibiotic residues are of significant concern in the ecosystem because their capacity to mediate antibiotic resistance development among environmental microbes. This paper reviews recent technologies for abatement antibiotics from human urine and wastewaters. Antibiotics widely distributed aquatic environment as a result discharge municipal sewage. Their existence is cause worry due potential ecological impact (for instance, resistance) on bacteria background. Numerous contaminants that enter wastewater treatment facilities environment, result, go undetected. Sludge can act medium some chemicals concentrate while being treated wastewater. The most sewage sludge has undergone spread agricultural land without properly checked pollutants. fate soils hence poorly understood. idea Separation at source recently been propagated measure control flow pharmaceutical into centralized plants (WWTPs). With ever increasing acceptance separation practices, visibility awareness dedicated treatement needed. Human urine, well conventional WWTPs, point sources micropollutants contributing ubiquitous detection receiving water bodies. Focused post-treatment source-separated includes distillation nitrification, ammonia stripping, adsorption processes. Other reviewed methods include physical biological methods, advanced oxidation processes, host combination methods. All these aimed ensuring minimized risk products returned environment.
