Due to the limitation of chemical process technology and management system, traditional treatment mode heavy metal waste liquid pollution has many problems, such as high power consumption in process, wear consuming steel, cost, secondary caused by complex solid residue data detection. Team based on front end deep learning module backend soft measurement model collaborative structures, design im...

Fe-MOFs were prepared using a solvothermal method, and characterized by scanning electron microscopy. We explored the application of as an adsorbing material for removal Rhodamine B (RhB) from aqueous solutions. The experimental data simulated dynamics results showed that pseudo–second-order kinetics model was appropriate analysis RhB removal. studied adsorption capacity MOF materials under dif...

Wastewater is an inevitable product in industry. How to remove fine particles and enhance the impurity removal efficiency of wastewater purification equipment has always remained a hotspot issue. In this study, novel hydrocylone with bi-symmetrical involue inlet, thick-wall overflow pipes conical segment structure was designed compared other hydrocyclones including different structures inlets, ...

Conventional wastewater treatment, primary and secondary treatment processes with simultaneous phosphorus precipitation, is the most common process combination used in Finnish wastewater treatment plants (WWTPs). It typically eliminates most of the organic load and phosphorus, as well as part of the enteric microorganisms present in raw wastewater. Municipal secondary effluents still contain so...

The environmental impact of industrial technologies and related remediation methods are major research trend lines. Unfortunately, in the development materials for wastewater treatment or air purification, hazardous reactants often employed, reducing overall beneficial contribution such technology on environment. We here synthesize stable titanium dioxide (TiO2) sols using a green route, with t...

the photocatalytic activity of nano-tio2 has been used in inactivation of microorganisms, mainly in the form of suspension in a liquid or partially in an immobilized system. using advanced oxidation processasa new approach has been used in the purification of water and wastewater. in this research, the systems of suspended (0.1 g/l) and immobilized nano-tio2 in the cement bed (0.1-2%) under a 1...

this research compares the performance of floating systems planted with vetiveria zizanioides as a hydroponic approach for removing nutrients from two contaminated waters. for this purpose, two pilots with overall net volume of 60 litres were constructed and inoculated by secondary treated domestic wastewater (stdw) and irrigation water obtained from minab reservoir (iwmr) in batch mode. regard...

the objective of this research was to conduct a bench scale study of fixed activated sludge treating domestic sewage. two different units employing diffused aeration with plastic and aluminum media were studied in four separate phases. data indicated that the system could produce a high quality effluent without any requirements for sludge recycling through the system. suspended solids concentra...
