Towards a Dynamic Compartmental Model of a Lamellar Settler

Lamellar settlers are widely used in solid separation due to their relative high surface area paired with a small tank volume. Settlers exposed load variations may change settling properties based on the variation of flow pattern. Applying critical point theory and coherent structure concept, topology analysis was performed help computational fluid dynamic simulations. The compartments were determined by flow, behavior taken into account. Under normal diurnal variation, architecture did not change, contrast mass transport between zones, whereas sludge removal process made significant changes architecture. results showed two main zones internal recirculation first zone. hydraulic loading examined each zone, study revealed that actual could be from 1.5 4.5 times much higher than individual eddies reactor tanks. design rate consider local discrete phase model approximation provided acceptable results, extent zone changed stepwise different loads.
