Cleaning Strategies and Cost Modelling of Experimental Membrane-based Desalination Plants

In Project WASTEC, an experimental Reverse Osmosis (RO) desalination system was developed. It serves as a platform for testing new technologies. For this system, we solved two problems, which are described in paper. Firstly, developed and investigated strategies scheduling chemical enhanced backwashing cleaning secondly, due to the nature of project, several technological developments with respect materials methods were integrated into requires tools evaluating economic viability task, economics membrane-based will be investigated. Baseline systems reverse osmosis pretreatment (microfiltration ultrafiltration) economically examined compared their investments operational costs. Sensitivity different plant membrane parameters cost studied. Results show that costs, 200m3/hr design capacity plant, volume water is produced by MF process at $0.494 $0.486 ultrafiltration microfiltration. The cannot directly, but it required $ 0.49 / m3 56 m3/hour capacity. values line costs reported literature filtration.
