Maximising the air scouring performance of novel membrane modules

Membrane scouring of novel flat sheet membrane modules was optimised using computational fluid dynamics (CFD). Shear stress on membranes for fouling prevention was quantified by CFD. Increased viscosity (rheology) due to high MLSS (activated sludge concen

Our client, the Belgian company Blue Foot Membranes has commercialised the IPCTM ('Integrated Permeate Channel') membrane: a fully backwashable flat sheet membrane. We used advanced 3D modelling to optimise the air scouring over the membranes and across the module. Eight different virtual prototypes with varying aerators and aerator configurations were evaluated within a few weeks without the need to build and test physical prototypes.

Membrane design factors to consider for microfiltration, ultrafiltration design

The model accounted for:

Fine and coarse bubble aeration
High sludge concentration
Fow patterns (i.e. shear) along the membrane surface

Advanced treatment

Predicting and minimising bromate formation in indirect potable reuse with AMOZONE - the SWIFT project (US)

The AMOZONE simulation model predicts bromate formation, suppression and target contaminant removal (eg 1,4-dioxane) during ozonation for indirect potable reuse (HRSD, SWIFT)

Large Basins

Large reservoir mixing: CFD-based improvement (Netherlands)

Optimal design of inlet and aeration in drinking water basin using computational fluid dynamics (CFD) modelling. Aeration was taken into account. Multiphase CFD simulation of air and water. Shortcircuiting and dead zones avoided. Optimal hydraulic reside

Crystallisation

Design of a crystalliser - Urine treatment for phosphoruous recovery via potassium struvite precipitation

This crystallisation process was designed using computational fluid dynamics (CFD). Baffle, mixer (impeller) type and speed, reactor configuration was optimised using 3D multiphase cfd modelling. This was a struvite reactor.
