Studies were carried out of a new, unconventional method for phosphorus removal from wastewater, making use of the phenomenon of metals corrosion in wastewater. Metal ions are introduced to the solution as an effect of corrosion, instead of the up till now applied coagulation method. Likewise in the coagulation process, as a result of the occurring reactions (simplifying the mechanism more complicated in practice), sludge precipitates containing among others phosphorus. The experiments were carried out with media contain steel and aluminium. The most effective in phosphorus removal from wastewater was the uniform steel medium. The concentration of 1 mg P dm⁻³ orthophosphates in the effluent seems very realistic and even lower values can be achieved.
