“…The need to take action in this area in support of the European Green Deal and Sustainable Development Goals, especially SDG 6: ''Ensure the availability and sustainable management of water and sanitation for all'', is just as important. The implementation of the provisions of the above-mentioned documents involves an intensification of the search for alternative solutions to wastewater and water treatment, reduction of generated waste, or the use of readily available natural materials (Paweska and Bawiec 2017;Doman ´ska et al 2019;Garbowski et al 2020;Burszta-Adamiak and Spychalski 2021). Because of the significant problem posed by heavy metals to the environment and humans, this issue has been intensively studied in recent years.…”

The use of materials of natural origin for the adsorption of heavy metal ions from aqueous solutions has gained attention in recent years among the scientific community. This is explained by the fact that nickel compounds, due to severe health consequences, are considered to be among the most dangerous to the environment. This article reviews the results of studies on the use of biosorbents for purification of aqueous solutions from nickel ions, and then attempts to classify them according to their origin. The characteristics of materials and their sorption capacity have been compared, and the removal mechanisms identified of which chemisorption and ion exchange are considered to be the most common. From the analyses, a major trend is the use of biomass; however, biosorbents from other groups also continue to attract the interest of researchers. Conducting laboratory studies can help select materials with high efficiency. The highest sorption capacity values for the materials in each group were: for waste products 56 mg Ni·g−1 (olive stone), for peat 61 mg Ni·g−1, for miscellaneous 225 mg Ni·g−1 (microbial flocculant GA1), for biomass 286 mg Ni·g−1 (Plantanus orientalis bark) and for composites/modified materials calcinated eggshells 769 mg Ni·g−1 (calcinated eggshells). However, for some materials the sorption phenomenon may be accompanied by precipitation in the presence of hydroxides, which significantly affects the sorption capacity achieved. There is a need to transfer these experiments to an industrial scale so as to verify their applicability. In such industrial scale applications, attention should be paid not only to the effectiveness of the material, but also to its availability, price, and ease of use, as well as the effect of the biosorbent in terms of changing the quality parameters of the aquatic environment.

“…Moreover, according to results from a waste water treatment plant in Gorzów Wielkopolski (western Poland), the membrane technology reliably removes not only suspended solid ingredients, but also other waste water pollutants. Statistical analysis confirmed the high efficiency of treatment [62]. The conducted research indicates the high efficiency of domestic waste water treatment, also in terms of the removal of substances of emerging concern.…”

Recovering water from waste water is increasingly used. It is a part of the circular economy, enabling saving water resources. The EU regulation to use reclaimed water to irrigate crops regulates the principles of appropriate water quality preparation and indicates the possibilities of its use. An important element of the regulation is the obligation to carry out a risk assessment as the basic tool to ensure safety in the use of reclaimed water. One of the uses of reclaimed water on green areas could be ski resorts producing artificial snow. The solution to produce artificial snow from reclaimed water is still not popular. No case realized in Europe could be found, although attempts were made in the Alps to implement such projects. Australia and the USA have the most experience. Despite the positive aspect of water recovery, there are questions about the impact of snow produced in this way on the environment and the safety of users. The first project to produce artificial snow using reclaimed water appeared in Polish ski resort Kasina. Its purpose is to feed the snow guns with water coming from the local waste water treatment plant. The quality parameters of water recovered as a result of MBR technology indicate that it meets the legal requirements; however, the plant operator did not receive a water permit. The solution may be to conduct a reliable risk assessment for this local solution.

“…Full-scale membrane bioreactor technology is a coupling of two wastewater treatment methods, biological treatment and membrane separation (Domańska et al 2007;Judd 2008;Huang et al 2010). Conventional treatment of municipal wastewater generally involves three-stages: sedimentation of solids in the feed water (primary treatment), coupled with a coagulation stage when it rains for example, followed by treatment of organic matter by aerobic degradation, e.g., activated sludge and secondary treatment, and finally a second sedimentation process to remove biomass.…”

Removal of emerging contaminants from wastewater using advanced treatments. A review

et al. 2022

View full text Add to dashboard Cite

The rise of emerging contaminants in waters challenges the scientific community and water treatment stakeholders to design remediation techniques that are simple, practical, inexpensive, effective, and environmentally friendly. Emerging contaminants include antibiotics, hormones, illicit drugs, endocrine disruptors, cosmetics, personal care products, pesticides, surfactants, industrial products, microplastics, nanoparticles, and nanomaterials. Removing those contaminants is not easy because classical wastewater treatment systems are not designed to handle emerging contaminants, and contaminants often occur as traces in complex organo-mineral mixtures. Here, we review advanced treatments for the removal of emerging contaminants in wastewater, with focus on adsorption-oriented processes using non-conventional adsorbents such as cyclo-dextrin polymers, metal-organic frameworks, molecularly imprinted polymers, chitosan, and nanocellulose. We describe biological-based technologies for the degradation and removal of emerging contaminants. Then, we present advanced oxida-tion processes as the most promising strategies because of their simplicity and efficiency.
