“…The phytotoxicity tests of the samples were performed in parallel with the physicochemical assessment. To describe the results of ecotoxicological analyzes, a unified concept of the toxic effect was used, denoted as E (%) [21]. Negative frond growth inhibition values mean stimulation of their growth.…”

Swimming pools are examples of water-intensive facilities, where solutions for reducing economic and environmental costs are increasingly frequently searched. One of the solutions is the recovery of water from wastewater, including from washings obtained through the process of rinsing filter bed. The study objective was the qualitative and quantitative assessment of post-coagulation sludges, the main pollutant found in the washings. During the analyses, assessment of the sedimentation capabilities of the sludges was performed (gravitationally), particle size distribution was assessed (particle size distribution analyzer) and assessment of phytotoxicity with the use of plant indicators in short-term tests was performed (Lemna minor, Lepidium sativum, Sinapis alba, Raphanus sativus). The samples were collected from two independent circulations, which differed in terms of capacity and type of coagulant used. The tested post-coagulation sludges were characterized by high content of total suspended solids: in samples from Circulation 1 from 251 to 128 mg/l, in Circulation 2 from 489 to 228 mg/l. However, the sedimentation processes enabled significant separation of sludges. The hydrolyzed coagulant contributed to the improvement of sedimentation capabilities of sludges. Despite the fact that in many samples low sludge concentrations favored stimulation of plant growth, the post-coagulation sludges can constitute a hazard to plant growth, particularly in the long-term perspective.

“…Negative frond growth inhibition values mean stimulation of their growth. The samples are classified according to the magnitude of the toxic effect: I < 25% -non-toxic; I = 25.1 -50% -low toxic; I = 50.1 -75% toxic; I = 75.1 -100% -highly toxic [21].…”

“…Other common and concerning examples of PPCP (pharmaceuticals and personal care products) are pharmaceuticals (ethynylestradiol, carbamazepine, and ibuprofen) and antimicrobials (triclosan) [ 6 ]. These are persistent organic pollutants, including compounds and toxic substances [ 7 ]. Research has shown [ 8 ] that ammonia monooxygenase is responsible for the biodegradation of triclosan.…”

In this study, we examined the sorption of selected “chemicals of emerging concern” (CEC) on humic substances commonly found in water and municipal wastewater. These were ibuprofen, diclofenac, caffeine, carbamazepine, estrone, triclosan, bisphenol A, and isoproturon. The humic substances (HSs) were synthetic and not contaminated by the tested organic substances. The elemental composition and content of mineral micropollutants, gravimetric curves, and the IR spectrum of HSs were determined. We determined a relationship between the process efficiency and the characteristics of a sorbent and sorbate using the properties of organic substances sorbed on HSs. This relationship was confirmed by sorption tests on the HS complex, i.e., the HS-organic micropollutant. It has been shown that the given complexes have a greater affinity for hydrophobic surfaces than hydrophilic surfaces. To confirm the nature of the sorbent surfaces, we determined their zeta potential dependence on the pH of the solution. Studies have shown that HSs are carriers of both mineral substances and CEC in water and sewage environments.
