The treatment of spent oil-in-water emulsion (SOWE) from a non-ferrous metal-processing plant by using aluminum sulfate and hydrated lime was studied in order to determine the purification efficiency, optimize the operating conditions and scale up the treatment process. The purification efficiency was estimated by comparing the compositions of the SOWE and the processed wastewater. The treatmen...

Cenococcum graniforme, Suillus luteus, Thelephora terrestris, and three isolates of Pisolithus tinctorius were cultured on modified Melin-Norkrans medium at pH 3.4 and adjusted to 0 to 500 ppm (0 to 500 mug/ml) of aluminum or manganese sulfate. Except for T. terrestris, which was intolerant of aluminum at 150 and 250 to 500 ppm, and P. tinctorius isolate 250, which was intolerant of aluminum at...

Two commercially available litter treatments, aluminum sulfate and sodium bisulfate, were tested to determine their effect on Campylobacter and Salmonella levels associated with commercial broilers during a 6-wk grow-out period. A total of 20 broiler houses at 10 different locations were studied; 5 aluminum sulfate-treated houses, 5 sodium bisulfate-treated houses, and 10 paired, untreated cont...

Aluminum compounds were first identified as adjuvant over 90 years ago [1]. Adjuvants (immunopotentiators or immuno modulators) in vaccine formulations aim to enhance, accelerate and prolong the specific immune response towards the desired response to vaccine antigens. Advantages of adjuvants include the enhancement of the immunogenicity of antigens, modification of the nature of the immune res...

Abstract The high alkali content of alkaline accelerators has a negative influence on the late strength and durability concrete. Further, their corrosive nature is harmful to skin construction personnel, posing safety concerns. Therefore, development alkali-free gained interest, especially in shotcrete-based constructions. production process aluminum-sulfate-based simple less exothermic, with n...

Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa domesticus) manure may contribute to eutrophication. The objective of this study was to evaluate the effect of aluminum sulfate (alum) and aluminum chloride applications to swine manure on P runoff from small plots cropped to tall fescue (Festuca arundinacea Shreb.). There were six treatments in this study: (i) unfertilized con...

B-Zn-Si-Al compounds are modified Si-Al compounds made of sodium silicate, zinc sulfate, borax, and aluminum sulfate. They act as a fire retardant during the preparation of ultra-low density fiberboards (ULDFs). An orthogonal experiment was used to optimize the contents of the four compounds according to the limiting oxygen index. Fourier transform infrared spectroscopy was employed to prelimin...

24 Aluminum coagulants are widely used in water treatment plants to remove turbidity and 25 dissolved substances. However, because high aluminum concentrations in treated water are 26 associated with increased turbidity and because aluminum exerts undeniable human health 27 effects, its concentration should be controlled in water treatment plants, especially in plants 28 that use aluminum coagu...
