Currently, much attention is paid to the treatment of industrial wastewater, which would provide the necessary degree of decontamination for organizing a recycled water supply and further disposal of the treatment-generated by-product. The paper presents an advanced technology using a new nanomaterial that decreases initial concentrations of heavy metal ions in electroplating production wastewater from 25 g/L to less than 0.6 mg/L. An integrated process of wastewater treatment consists of two stages: energy- and resource-efficient ferritization followed by sorption onto suspensions of nanopowders of polyvalent iron oxides. The advantages of an electromagnetic pulse method for achieving ferritization at frequencies up to 0.9 kHz in comparison with expensive thermal treatment at temperatures up to 75 °C are demonstrated. The polyvalent iron oxide nanosorbents were obtained by electroerosion dispersion. The result of the integrated treatment is that the purified water meets the requirements for water reuse in electroplating production. The treatment-generated by-product has high chemical stability and a significant content of magnetic ferrite phases, thus having a high potential for further utilization. In contrast to the widely used reagent-based treatment of concentrated wastewater contaminated by heavy metals (> 25 g/L), the integrated method developed here prevents environmental contamination by toxic effluents and ensures the rational use of water and energy inputs in the system of industrial production.","PeriodicalId":39996,"journal":{"name":"Nanotechnology Perceptions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46015182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two linked methods are considered. The first, termed the gradualist approach, assumes that the R-rate is controlled to a value close to 1.0 and that the social distancing index (SDI), which measures the nation’s level of interpersonal contact, is allowed to increase continuously to the point where it can grow no further and society and the economy are fully open. The second method, termed the two-step strategy, adopts the gradualist approach initially, but then, after a certain time, the SDI is stepped to its maximum value, which implies the immediate removal of all restrictions. It is found that, while vaccination-generated immunity makes a very valuable contribution to overall immunity, the other components—prior T-cell immunity and immunity generated by infection—are just as important. Infection-generated immunity needs to be the largest component if all restrictions are to be removed, under both strategies. Leaving lockdown to the point where all restrictions can be fully eased requires a narrow path to be followed during the spring and early summer of 2021, keeping the R-rate in a central band around 1.0. Close control of the R-rate is needed and this will require it to be measured accurately, continuously and rapidly. The gradualist approach might allow all restrictions to be lifted by the end of the summer 2021, while the two-step strategy might offer the prospect of full derestriction by the end of May 2021. © 2021 Collegium Basilea.","PeriodicalId":39996,"journal":{"name":"Nanotechnology Perceptions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48937984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
