Objective 1: Investigate nutrient recovery systems’ performance and coordination and understand their applicability to the wastewater network in a circular economy of nutrients.
Objective 2: Identify and analyse performance barriers (e.g. technical, financial, compatibility, capacity) that currently limit how these systems can integrate well into circular nutrient economies within the Australian context.
Objective 3: Understand and analyse the water utilities’ perception in the circular nutrients’ systems business model and how these new systems enable or impede the effective transition to circular nutrient economies.

Objective 1: To develop ion selective membranes with sulfonated polyether ketone polymer for membrane capacitive deionisation system. The development of a sulfonated polyether ketone composite membrane using Lithium selective adsorbents and nanomaterials as the fillers with high ionic conductivity and selectivity to be incorporated as a cation exchange membrane for membrane capacitive deionisation system.
Objective 2: To develop metal organic framework-on-sulfonated polyether ketone membrane with high Lithium-ion selectivity and permeability. Lithium ion to monovalent ion selectivity of an ion selective membranes will be boosted by creating a thin metal organic framework layer on the sulfonated polyether ketone substrate.
Objective 3: To understand the fundamental of ion transport within ion selective membranes. Computational and analytical models using molecular dynamic simulation and density functional theory will be used to confirm the experimental data (Aim 2) and provide insights into the mechanisms of selective ion transport within the membranes.
Objective 4: To develop solar-driven membrane capacitive deionisation electrochemical process for selective Lithium-ion recovery. The membrane capacitive deionisation system will be optimised in terms of cost and energy efficacy and scaled-up for selective Lithium-ion recovery from various salt solutions.
