The solvent extraction of copper by bis(2,2,4-trimethylpentyl) phosphinic acid (CYANEX272) in kerosene from a pregnant solution of aqueous spent deposited sludge of transformer oil containing 1243.4 mg L Cu, 389.2 mg L Fe++/+++, 110.7 mg L Ca and 235 mg L Al was studied. The results ...
In these areas, the sludge particles are condensed due to electroconvection. It is shown that sludge spraying on the surfaces of various elements of the contactor leads to an increase of the electric field near these surfaces and increases the possibility of a breakdown in the isolation....
oilIn this study, possible toxicity of increasing doses of PCB-118 and transformer oil (TO) on anaerobic sludge digestion was investigated. For this purpose, five different sets of reactors were prepared in which four different PCB-118 concentration (1, 10, 20, and 30 mg L−1) and...
