Economic Model Predictive Control for optimal struvite recovery
Journal of Environmental Management, 2021 Resource recovery from municipal wastewater has been a prime focus for a decade. Although several recovery processes already exist in the market today, the high cost of material, inherent disturbance in the influent quality, lack of real time monitoring of critical parameters, and lack of a robust automation system may result in suboptimal performance.

PHOSPHORUS RECOVERY FROM WASTE AS STRUVITE
Ecological Engineering and Environment Protection, 2020 The paper gives information on the depletion of phosphorus (P) as an important element for all forms of life and its pollution impact on the environment in case of intensive discharge of phosphorus compounds into water bodies. Two secondary waste sources of Phosphorus are under consideration, namely the domestic wastewater and sludge and animal manure.

Journal of Environmental Chemical Engineering, 2022 Microbial mineralisation is attracting significant interest as an innovative process to recover nutrients from waste streams. Nevertheless, little is understood about the requirements to form struvite using biological pathways in wastewater and how does this compare with traditional chemical processes.
