Rapid urbanization has led to the exploitation of water quality and quantity. Urban growth and its activities result in the pollution of freshwater by generating different types of waste. Root Zone Technology (RZT) has successfully been adopted and employed in several countries to promote sustainable development. RZT paves the way for the incorporation of automated dynamics into an artificial soil ecosystem. This study’s primary goal was to develop a water treatment process for industrial effluents naturally and effectively using RZT. The technology adopts layers of coarse and fine aggregates, charcoal, sand, and planted filter beds consisting of compost media to treat effluents; the system is easily installed, low-maintenance, and has low operational costs. Selected plants achieved a result of 50–80% pollutant removal. RZT reduces the characteristics of effluents, such as chemical oxygen demand, biochemical oxygen demand, pH, color, TSS, TDS, BOD, COD, etc., by a more significant amount. Further studies of more plant species should be performed to improve this technology. Soil tests will also be an excellent option for understanding the concepts of reed absorption mechanisms. In addition, incorporating modeling in agricultural systems will be beneficial for future studies.
To date different technologies based wastewater treatments have been actualized at full scale level over the world; however the integral elements for the determination of most suitable treatment framework are still obscure . The present study is fervent to the investigation of 11 decentr alized sewage treatment plants in Northern India using a qualitat ive approach methodology in which distinctive focus was paid to ec onomic indicator of these plants. A total of eight technolo gies i.e. Package type (including Anaerobic , Anaerobic +Aerobic treatment and Anaerobic +Aerobic treatment ), and cluster type, i.e. Extended Aeration (EA), Moving bed Bio-film Reactor (MBBR), Sequencing Batch reactor (SBR), Membrane Bio reactor (MBR),Rotational Biological Contractor (RBC) were counted in this field review. As a component of the q ualitative evaluation of these plants, land requirement, capit al investments, operation and maintenance (OM Specific power consumption @ < 0.7 (±10%) KW- h/m3 for design flow and 0.15 to 1.76 (±10%) KW-h/m3 for Actual Flow, technical performance was pragmatic with % BOD removal @ 65 to 98%, % COD removal 66 to 98 % and % TSS removal 65 to 97 % .These results give a test and a n opportunity for the research community and market leader to choose a suitable option of similar regions. The results of this study allow users and engineer to choose the treatment system a ccording to their resources available viz. -a- viz. requirement .
A DFT study of the enantioselective organocatalytic intramolecular Morita–Baylis–Hillman (IMBH) reaction of enones under the influence of 1,1,1,3,3,3-hexafluoroisopropanol is reported. This study establishes an excellent fit between the experiment and theory.
