Fabrication of an innovative magnetic zirconium tungsto-vanadate hybrid in different nano-architectures and its implementation as selective cation exchanger for wastewater treatment

Starting date: 2014

End date: 2016

PI: Prof.Marwa Elkady

Funded by: STDF

Summary:

Respecting to the hazardous of pollutants in wastewaters, there is an urgent need for preparation of an innovative inorganic ion exchanger namely zirconium tungsto-vanadate ion exchange material. This innovative ion exchange material will be doped with different exchangeable alkaline metal elements such as sodium, calcium, magnesium and potassium as an attempt to improve its selectivity for the harmful ions neither the useful minerals ions from the polluted wastewater. These properties may be acquired through developing this ion exchange material in different architectures either nano-particles or nano-rods using chemical or thermal modification processes. However, these small particle sizes of the prepared materials are difficult to be handled in the wastewater treatment processes either the batch or continuous processes. So the prepared nano- zirconium tungsto-vanadate ion exchange material and its dopant will be immobilized with nano-magnetic particles to prepare selective nano-magnetic ion exchange hybrids easily to be separated from the treatment media by external magnetic field. Furthermore, considering the continuous treatment process, the presence of external magnetic field around the treatment column that contains the fabricated nano-magnetic ion exchange hybrid will be facilitate the flow of wastewater and reduce the pressure drop inside the treatment column that improve its treatment performance. Accordingly, in order to simulate the industrial wastewater treatment process, a prototype fluidized bed tower packed with the most efficient fabricated nano-magnetic ion exchange hybrid material will be designed as the main constituent at the prototype constructed treatment unit to study the continuous treatment process.

 

Objectives and Impact:

This research project contribute in solving two serious problems in parallel that Egypt suffering from, which are the water scarcity and environment pollution. This goal was achieved through water saving by reusing the treated industrial wastewater at the cooling circuits inside the different factories that discharge these polluted wastewaters or to be used for agriculture purposes.

SDGs that the project achieved: GOAL 6: Clean Water and Sanitation.
