“…Comparing with other studies, the values of pH were in the same range (Onchoke et al, 2022), while another study carried out in the USA with a lower number of WWTPs (Onchoke et al, 2018) showed narrower ranges for C (30-32%) and N (8-10%), and higher values of P (935-1705 mg kg −1 ), and Ca (1,521-3,869 mg kg −1 ), but the maximum values of Mg (709 mg kg −1 ), K (679 mg kg −1 ), Na (2,303 mg kg −1 ), Al (12,857 mg kg −1 ), Cr (20 mg kg −1 ), Mn (1,103 mg kg −1 ), Fe (22,688 mg kg −1 ), Ni (19.8 mg kg −1 ), Cu (550 mg kg −1 ), Zn (772 mg kg −1 ), As (13 mg kg −1 ), Cd (0.5 mg kg −1 ), Hg (0.6 mg kg −1 ), and Pb (34 mg kg −1 ) were significantly smaller than the maximum concentrations detected in our samples. Similarly, in a study in Poland Latosinska et al (2021) reported that the maximum concentrations of Cu (196 mg kg −1 ), Cr (2,760 mg kg −1 ), Cd (12 mg kg −1 ), and Ni (44 mg kg −1 ) in sludge were smaller than in our samples, but Pb (427 mg kg −1 ) and Zn (5,351 mg kg −1 ) showed higher concentrations.…”

The huge worldwide use of antibiotics triggers the accumulation of these substances in sludge from wastewater treatment plants (WWTP) and the possible contamination of soils amended with it, as well as of crops growing in these soils. In this work we analyzed the presence of the antibiotics amoxicillin (AMO), cefuroxime (CEF), ciprofloxacin (CIP), clarithromycin (CLA), levofloxacin (LEV), lincomycin (LIN), norfloxacin (NOR), sulfadiazine (SUL), and trimethoprim (TRI), in sludge from different WWTPs in Galicia (NW Spain), as well as in sludge technically treated by waste-managers, in soils where treated sludge was applied, and in crops (corn and vineyard) growing in the amended areas. The antibiotics were quantified by means of high resolution HPLC-mass-chromatography. The results indicate that almost all the sludge samples contained antibiotics, being ciprofloxacin and levofloxacin the most abundant reaching maximum values of 623 and 893 ng/g, respectively. The sludge treatment significantly reduced the number and the concentrations of antibiotics. In 12% of the soil samples where sludge was applied, some antibiotics were detected, but always in small concentrations. Regarding the crops, no antibiotic was detected in the roots, stalk, leaves and grain of corn, neither in grapes sampled in vineyards. It can be concluded that the treatments currently applied in the WWTPs under study are not totally effective in removing antibiotics from the sludge, although the findings of this research suggest that the additional specific treatment of the sludge derived from these WWTPs is effective in reducing the risk of environmental pollution due to a variety of antibiotics, and specifically in the case of soils amended with these organic materials and crops growing on it.

“…Municipal sludge is an extremely complex heterogeneous body consisting of organic pieces, inorganic granules, bacterial colonies, flocs, etc . During the disposal of industrial wastewater and domestic sewage, large amounts of suspended colloid substances are produced and the mixed dispersion system consisting of these substances is called sludge.…”

Municipal sludge is an inevitable byproduct during the treatment of wastewater, which is produced by sewage treatment plants in urban residential areas, and it contains pathogens, heavy metals, and other pollutants. Municipal sludge is suitable for application in energy utilization because of its high organic content and relatively low toxic matter. The high moisture content of municipal sludge brings huge difficulties to its harmless disposal and resource utilization. At present, the main method used for sludge dehydration is mechanical dewatering. However, the mud cake produced by this method still has a water content of up to 80%, which does not meet the current rigorous requirements. Therefore, the development of deep dehydration technology for sludge is imperative. In this paper, the basic properties and structure of sludge were summarized. As a key component of sludge flocs, extracellular polymeric substance (EPS) has received much attention in sludge dewatering conditioning. Meanwhile, the influencing factors of sludge dewatering were also fully elaborated, including sludge types, sewage hardness, surface charge, size distribution, and sludge viscosity. And the main methods of sludge dewatering treatment were comprehensively included, namely, the physical method, chemical method, biological method, and combined conditioning methods. The advantages and disadvantages of each method are mentioned, and their application situations were analyzed. Furthermore, comment was provided on the conditioning mechanism, adaptability, prospects, and limitations of the techniques for improving sludge dewatering. This systematic review related to sludge dewatering can not only provide reference information for the conditioning method but also benefit the exploitation of efficient and ecofriendly sludge dewatering technology.

“…Despite the fact that WWTPEs only contain the pollutants mentioned at trace concentrations, they seem to be toxic to a variety of organisms. Onchoke et al (2022) supported the need to design analytical methods to detect pollutants. The use of biomonitoring assays may also enhance the characterization of such discharges.…”

The possible effects of wastewater treatment products on mussels (Mytilus galloprovincialis) were studied. Three common pollution biomarkers were used: neutral red retention assay, malondialdehyde contents and DNA damage through comet assay. Two groups of mussels were treated in the laboratory for 25 days with 20 and 40 %v/v of treated wastewater collected after chlorination, the control mussels formed a third group. The results showed statistically significantly lower neutral red retention times, higher malondialdehyde contents and higher formation of single-stranded DNA fragments in the mussels exposed at both treated wastewater concentrations compared to the controls.
