Current challenges
___
-
Most of Chinese RO manufacturers do not have their own system design and performance prediction tool an rely on international brands such as WAVE® by Dupont, IMSDesign by Hydraunautics etc. which do not capture the real characteristics of their own membrane products;
-
Design software developed by international RO suppliers
-
Use empirical correlations to derive concentration polarisation/fouling factors
-
Does not consider performance deterioration over time;
-
Both brackish water and seawater RO membranes are widely used in China to treat high salinity industrial wastewaters, however, design software developed by international RO suppliers may not capture the information on industrial wastewaters in their database;
-
Competitive advantage
___
-
Expandable database for clients to add information on their membranes;
-
Computational Fuild Dynamics powered simulations to derive more accurate concentration polarisation factors;
-
PhreeQC compiled for improved representations of chemical speciation, osmotic pressure calculations and scaling predictions
-
Adaptive, reliable and accurate predictions of performance and chemical dosing requirements through modelling the variations of key parameters over long-term operation by machine learning algorithms.
