Demulsification of emulsified water-in-oil droplets was worked out with the employmentof wetting coalescence materials.Demulsification is carried out in conventional stirred-column andpacked-column.Among the four kinds of natural fibers and two kinds of inorganic materials tested,natural fiber A,originated from wood shavings was found to give the best performance of demulsifica-tion.The demulsification efficiency can exceed 96.5% when demulsification conditions are optimized.The packed-column showed much better performance both in terms of demulsification efficiency andrepeated use of the recovered oil phase for extracting cadmium in simulated wastewater.Operatingvariables governing the demulsification efficiency were investigated.
Demulsification of emulsified water-in-oil droplets was worked out with the employment of wetting coalescence materials. Demulsification is carried out in conventional stirred-column and packed-column. Among the four kinds of natural fibers and two kinds of inorganic materials tested, natural fiber A , originated from wood shavings was found to give the best performance of demulsifica- tion. The demulsification efficiency can exceed 96.5% when demulsification conditions are optimized. The packed-column shows much better performance both both terms of demulsification efficiency andrepeated use of the recovered oil phase for extracting cadmium in simulated wastewater. Operating variables governing the demulsification efficiency were investigated.
