WASTE WATER DISPOSAL USING SODIUM ALUMINATE AND SODIUM FERRATE

摘要

PURPOSE: A waste water treatment process using sodium aluminate and sodium ferrate is provided, which improves treatment efficiency without using excess inorganic coagulant and polymer. CONSTITUTION: The process is characterized by following chemical formula: Al2(SO4)3+6NaAlO2+12H2O comes to 8Al(OH)3+3Na2SO4; FeCl3+4NaAlO2+7H2O+HCl comes to Fe(OH)3+4Al(OH)3+4NaCl.
