Comparison of Traditional and Modified Technologies of Struvite Chemical Precipitation for Simultaneous Recovery of Phosphorus and Nitrogen from Aqueous Media
https://doi.org/10.18412/1816-0395-2026-5-32-37
Abstract
Adaptation of the modified struvite precipitation process to wastewater treatment technology of complex composition was carried out. It is noted that this technology eliminates the drawback of the traditional method associated with the need to use an excess of Mg2+, NH4+ or PO43- ions. It is concluded that the use of the modified technology made it possible to increase the degree of wastewater purification from NH4+ and PO43- to 95% and higher without using their excess, and to ensure a yield of high-quality precipitate up to 98–99%.
