Polyaluminium ferric chloride(PAFC) is an important new high efficiency inorganic flocculant and widely used in the fields of water treatment. Six kinds of preparation technology of PAFC were introduced, which are AlCl3/FeCl3 technology, AlCl3/Fe(OH)3 gel/CH3CH2OH technology, AlCl3/FeCl3/calcination technology, calcium aluminate powder technology, Fe2O3/ Al2O3l/H2SO4 technology and aluminium polychlorid/FeCl3 technology. It is found that the first four processes hare research value.
