Development of adsorbent materials for phosphate recovery
Phosphate, one of the primary components in fertilizers, is a finite resource in current scarcity, mainly obtained by the mining of phosphate rocks. In 2014, this mineral was declared as one of the 34 critical resources in the European Union. Phosphate rocks are geographically concentrated but …

A technological, economic and social exploration of phosphate recovery from centralised sewage treatment in a transitioning economy context
Phosphate is an important, non-substitutable nutrient for all life forms and is essential in ensuring universal food security. In the past, waste water treatment works (WWTW) typically installed effluent polishing technologies to eliminate phosphate and lower concentrations of both nitrogen and …

Evaluation of Hydraulic Separator Applications in the Coal and Mineral Industries
… associated with four coal plants and two phosphate plants are summarized in this work. In most of these applications, the high-efficiency units proved to provide a higher quality product at reduced costs when compared against the performance of conventional separators. As a result of this …

Exploring Forward Osmosis Systems for Recovery of Nutrients and Water
… large amount of nutrients that are available for recovery. In this study, a proof of concept process based on forward osmosis (FO) was proposed and investigated for in-situ formation of struvite from digested swine wastewater. This FO system took advantage of a drawback reverse solute flux (RSF) …

Multidimensional population balance modeling and optimization of continuous reactive crystallization
… world. During the production of phosphoric acid, phosphate rock is reacted with sulfuric acid producing gypsum as the byproduct that is separated from the phosphoric acid by filtration. The efficiency of filtration depends strongly on the crystal size distribution (CSD) and shape. Undesired gypsum …
