Precipitation methods are commonly used for removing phosphorus compounds from wastewater. Chemical precipitation method, based on adding iron, aluminium or calcium salts to the treated wastewater, is often used. Another possible way of precipitating phosphates is metal dissolution method, which is presented in this paper. The main difference between these two methods is how the phosphate precipitating ions are introduced to the wastewater.This paper discusses advantages and disadvantages of the metal dissolution method in comparison with traditional precipitation methods. Differences in the secondary contamination of treated wastewater by iron ions, conductivity, total alkalinity and pH correction process; the use of recyclable wastes; and energy consumption are discussed.
