Preparation and performance of a high purity poly-aluminum chloride

Introduction Coagulation is an established process for transforming colloidal particles into larger aggregates (flocs) and for adsorbing dissolved organic matter on to particulate aggregates so that these impurities can be removed in subsequent liquid/solid separation processes.

Synthesis and speciation of polyaluminum chloride for

Polyaluminum chloride (PACl) is a typical inorganic coagulant and generally produced by two steps including acid-dissolution of aluminum hydroxide and adding base to aluminum chloride until an empirical formula of Al(OH)nCl3-n (with n from 1.0 to 2.5) is achieved (Shen and Dempsey., 1998).

The new life of traditional water treatment flocculant polyaluminum

Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used occulation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst fl

Poly aluminum-ferric Chloride (PAFC) is a new type of high efficiency coagulant. In this study, high iron type gangue is used as a main raw material. It is calcined at 675 ¡ãC for 1 h and 3% CaF2 is added to the calcined powder and reacted with 20% hydrochloric acid at 93 ¡ãC for 4 h. The leaching ratio of aluminum ions is 90% and that of iron ions is 91%. After Fe2+ ions are oxidized in the

Alternative cost-effective preparation method of polyaluminium chloride

An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper. The proposed procedure is based on the use of granular aluminium metal, a common by-product of several aluminium-processing secondary industries, instead of using Al 2 O 3 (or of using a mineral containing Al 2 O 3) which is commonly applied by most industrial

large©scale precipitation synthesis of ¦Á©alumina with poly aluminum

Large©scale precipitation synthesis of ¦Á©alumina with poly aluminum

So, here, we investigated the large-scale synthesis of ¦Á-alumina by the precipitation method and with industrial grade poly aluminum chloride (PAC) as the aluminum precursor, for the first time. The synthesis procedure was optimized in terms of synthesis yield and facilitation of ¦Á-alumina formation by adjusting the concentration of the precursor (PAC) and precipitant (NaOH) solutions.
