Solid–liquid Separation of Activated Sludge by Flotation Using Microporous Ceramic Diffuser

Bio-Oxidation of Air-Borne Hydrophobic VOCs in Activated Sludge Aeration Tanks-Effects of Activated Sludge Concentration and Gas Diffuser

An activated sludge aeration basin (20 cm i.d., 140 cm height) equipped with either a coarse air diffuser (a plastic pipe perforated with 56 orifices of 2 mm in diameter) or a fine diffuser (porous plastic type with 100-micrometer pores) was utilized to treat an air-borne hydrophobic VOC (toluene, 700-800 mg/m). The purposes of this study were to test the influences of both MLSS and diffuser ty...

Gas transport and separation with ceramic membranes. Part II. Synthesis and separation properties of microporous membranes

Non-supported microporous silica (amorphous) and titania thin films were made by the polymeric gel route. The titania system consisted of particles smaller than 5 nm. Reproducible modification of supported y-alumina films with silica demands a strict control of every modification step. Silica films of 3060 nm thickness on top of and presumably partly inside the y-alumina film were realised. The...

Treatment of dairy wastewater by graphene oxide nanoadsorbent and sludge separation, using In Situ Sludge Magnetic Impregnation (ISSMI)

The present research investigates the ability of graphene oxide nanosheets for treatment of dairy wastewater, using In Situ Sludge Magnetic Impregnation” (ISSMI) to separate sludge after adsorption process. To increase the interaction between magnetic nanoparticles and graphene oxide, the former has been functionalized, using 3-Aminopropyl triethoxysilane, with the synthesized graphene oxide an...
