Comparative Technical-and-Economical Evaluation of Production Costs of Coagulant from Technical-Grade Aluminum Hydroxide and Hydroxide Sluge

Abstract




A comparative techno-economic estimate of the cost of HOAC producing from technical aluminum hydroxide and hydroxide sludge showed that the cost of HOAC would be decreased by 11% by using a hydroxide precipitate. The cost of operation on the hydroxide precipitate will decrease by 17.3% provided the storage vessel is converted into a reactor to neutralize the acid solution of HOAC. This is possible due to doubling the production of HOAC, moreover production volumes will amount to 7178.2 thousand rubles. The calculated payback period for capital investments for retrofitting is 1 month.





Keywords: coagulant, aluminum hydroxychloride, hydroxide precipitate, aluminum- containing waste
