background sewage sludge (biosolids) is a byproduct of wastewater treatment that accumulates in large quantities. effective stabilization and disinfection of sewage sludge prior to land application are necessary to not only protect human health, but also to induce the public its benefits and safety. currently, many wastewater treatment plants in iran dispose great amounts of untreated sewage sl...
متن کاملRheological characterization of centrifuged thickened waste excess activated sludge (EAS): the maceration effect on sludge pumpability
The purpose of this study is to determine how the rheological characterization of centrifuged thickened waste excess activated sludge (EAS). Wastewater treatment plants (WWTP) contain a number of transport operations of suspensions with special flow characteristics. Flow characteristics, in particular viscosity related effects, vary from very water-like to strongly non-Newtonian. This study use...
متن کاملEffect of Sludge Pre-Treatment Techniques on the Biogas Production from Waste Activated Sludge
Introduction There is a significant and inevitable fact in Turkey which is the “sludge problem” generated from the wastewater treatment plants. There are many sludge disposal techniques currently applied in Turkey such as incineration, landfilling, composting, etc.; but the disposal of sludge with those conventional methods is difficult and expensive, often requiring over 50 per cent of the ope...
متن کاملeffect of dissolved air flotation process on thickening of activated sludge
aims: sludge is an inescapable component of all wastewaters that originated from their treatment. dissolved air flotation (daf) process as an alternative clarifier is used in treatment of drinking water, pretreatment of wastewater, and as a phase separator in sludge activation processes. this study aimed to calibrated the usage of daf process in a laboratory scale and under various conditions, ...
