HEAD LOSS REDUCTION FOR PUMPING OF SLUDGE - Conferences
Webb13 feb. 2024 · The original sludge was taken from a sewage treatment plant in Shanghai, China, and the sludge was aged anaerobic sludge. The initial solid concentration was 480.5 g/L and then slowly diluted to 37.2 g/L. The sludge sample was stored at 4 °C (<1 week) prior to use. The characteristics of sludge samples are shown in Table 1. Webbing conditioning agents affects its rheological parameters. Knowledge of sludge rheology is critical as it provides basic information on pumping processes, pipeline design, and heat transfer [7,8].

Webb23 apr. 2014 · It can be expected that the rheological behaviour of thickened sludge is very similar. As was mentioned previously the rheological behaviour of sewage sludge depends on total solid soluble, but also content organic and inorganic substances per unit volume, number of particles and particle size distribution. Webb3 mars 2011 · Experimental results indicate that the sludge viscosity and rheogram peak can be used to assess inorganic water sludge dewaterability, but not that of organic activated sludge. Selecting proper rheological parameters for sludge conditioning control depends on sludge types and conditioning methods. WebbSludge treatment is increasingly focusing on reduction of volumes at all stages of handling. The yet thicker sludge causes excessive head loss, and either overly expensive … sanctuary mir4
