【 摘 要 】

This study deals with an issue of ammonia removal from anaerobic digestion's by-product - digestate. The aim of the research is ammonia removal by chemical precipitation using the combination of Mg2+, NH4+ and PO43-ions in struvite (MgNH4PO4 . 6 H2O). Laboratory tests were carried out using the sample of digestate liquor. The final product of the treatment may have the potential to be used as a fertilizer.
