precipitation is the method widely used for metal removal from ,acidic, effluent by raising the pH to the desired level to form an insoluble precipitate as hydroxides [25]. After adjusting the pH to the required level, the dissolved metal ,ions, are converted to insoluble solid phase via a chemical reaction with a precipitant agent such as lime.

The treatment of mine acid wastewater generally adopts the lime neutralization method. Iron and steel plant wastewater treatment uses anionic polyacrylamide as a flocculant to treat wastewater produced in steel plants. Anionic polyacrylamide only needs to be used in industrial wastewater treatment.

The pH value increases, the ,iron ions, precipitates. If pH is less than 2, H 2 O 2 cannot be discomposed to OH. by Fe2+ (5). According to all research it has been confirmed that the optimum pH of Fenton process is around 3 (2). The redox system and decolourization gives more stable results when pH is less than 3.5, Ferric ,ions, are easily
