As the ,pH, value of the ,wastewater, increases beyond about 10, excess calcium ions will then react with the phosphate. Because the reaction is between the lime and the alkalinity of the ,wastewater,, the quantity required will be independent of the amount of phosphate present. It will depend primarily on the alkalinity of the ,wastewater,.

pH, of animal manure ,wastewater, is also an important parameter controlling the for-mation of struvite. Hao et al. [15] stated that the highest purity of struvite was formed at ,pH, = 7.0, and the purity of struvite will decrease with the increase of ,pH,. When ,pH, is higher than 10, the precipitates mainly consist of Mg3(PO4)2 and Mg(OH)2. Therefore,
