Pressure drop prediction for efficient sludge pipeline design
Expanded Title:The measurement of the flow behaviour of non-Newtonian fluids such as sludge, also called rheology, is not a simple matter. Wastewater treatment sludges due to their non-Newtonian behaviour do not have a simple constant viscosity and therefore require more complex modelling. This has been researched world-wide but because the properties of sludges vary so much from plant to plant, there have not been much success in presenting pressure loss predictions. This study set out to measure the pressure drop versus flow rate on the waste water plants in existing pipes as well as the concentration of the sludges to independently test the design protocol developed. The study found that the rheological properties of 21 sludges from 6 WWTP’s in the Western Cape were tested ranging in solids concentration between 2% and 7.8%. Most test were done in tube viscometers which are really small pipelines. The sludges tested comprised of primary and secondary as well as filter bed sludge.
