Application of Waste Polymers as a Raw Material for Ultrafiltration Membrane Preparation

Preparation and characterization of ethanol-treated silk fibroin dense membranes for biomaterials application using waste silk fibers as raw material.

The possibility of producing valued devices from low cost natural resources is a subject of broad interest. The present study explores the preparation and characterization of silk fibroin dense membranes using waste silk fibers from textile processing. Morphology, crystallinity, thermal resistance and cytotoxicity of membranes as well as the changes on the secondary structure of silk fibroin we...

Application of Genetic Programming as a Powerful Tool for Modeling of Cellulose Acetate Membrane Preparation

Resource Reuse of Waste-Activated Sludge as Raw Material of Microbial Flocculant Preparation: Methods and Comparison

Resource reuse of waste-activated sludge (WAS) from a municipal wastewater treatment plant (WWTP) was introduced as raw material of microbial flocculant (MBF) preparation. With WAS samples of three concentrations, MBF preparation by various methods – including cation exchange resin (CER), CER-ultrasonication, CER-ultrasonication-CER, ultrasonication, ultrasonication-CER, and ultrasonication-CER...

Jordanian Zeolitic Tuff as a Raw Material for the Preparation of Substrates Used for Plant Growth

One of the problems faced in front of industry for potting media is limited amount of quality row materials (mainly peat) for unlimited production of quality substrates in the future. The using of natural minerals for production of substrates or as amendments for existing substrates is possible solution for this problem. The natural zeolites with their specific properties – high CEC, high conte...

A hazardous waste from secondary aluminium metallurgy as a new raw material for calcium aluminate glasses.

A solid waste coming from the secondary aluminium industry was successfully vitrified in the ternary CaO-Al(2)O(3)-SiO(2) system at 1500 degrees C. This waste is a complex material which is considered hazardous because of its behaviour in the presence of water or moisture. In these conditions, the dust can generate gases such as H(2), NH(3), CH(4), H(2)S, along with heat and potential aluminoth...
