TL;DR: In this article, the authors investigated the simultaneous removal of the total ammonia nitrogen (TAN), phosphate (PO4-P), and fluoride (F−) from semiconductor wastewater by chemical precipitation.

TL;DR: An economic assessment showed that the proposed adsorption process had a commercial attraction, and it was revealed that the phosphate combines with the biochar via electrostatic attraction, thereby forming a new outer-sphere surface complex and inner-spheres surface complex in the acidic condition.

TL;DR: A process performance evaluation indicated that M3 is more suitable for simultaneous K and P recovery from source-separated urine than M2, but the phosphate recovery efficiency was lower than that of M2 due to the dissolution of phosphate in the stabilizing agent.

TL;DR: In this article, an attempt was made to recover phosphate from swine wastewater through struvite crystallization using plant ash as the alkali reagent, and the maximum K-struvite purity was obtained at pH 10.

TL;DR: The findings indicated that the K removal could be slightly enhanced by prolonging the reaction time, which would correspondingly decrease the Na concentration in the precipitates; besides, the intermittent addition of MgCl2 could noticeably improve the removal efficiency of K by 6%, but simultaneously raise the Na content inThe precipitates recovered.
