In the present invention, aluminum sulfate and polyaluminum chloride (PAC), which are used as water treatment coagulants, are prepared by using aluminum dross, which is an oxide layer formed on the surface of a molten metal when dissolving aluminum metal or scrap. After the first preparation,...
Only by accepting criticism can we excrete all the dross of spirit. Only by absorbing other peoples opinions can we add new spiritual nourishment. - Xu Teli True modesty, is his open-minded, thinking the complete liberation, without any restraint, to take a pragmatic approach to all the ...
whereas in hectorite clay the metal oxide layer comprises magnesium. The surfaces of both hectorite and bentonite platelets are negatively charged because the divalent magnesium in hectorite is partly replaced by monovalent lithium, which results in a charge deficiency. Similarly, the aluminium in benton...
A wide variety of electrolytes can be used but since satisfactory results are obtained with simple inorganic salts it is generally preferred to use them as part or all of the electrolyte. Suitable salts include sodium, potassium, ammonium, calcium, magnesium and aluminium salts, particularly of car...
