The activated sludge process is a biological process used to oxidise carbonaceous biological matter, oxidising nitrogenous matter (mainly ammonium and nitrogen) in biological matter, and removing nutrients (nitrogen and phosphorus).

2012年6月1日 · Written by two leading environmental engineers, Biological Sludge Minimization and Biomaterials/Bioenergy Recovery Technologies offers a comprehensive look at cutting-edge techniques for reducing sludge production, converting sludge into a value-added material, recovering useful resources from sludge, and sludge incineration. Reflecting the ...

The activated sludge process is very widely used for biological wastewater treatment. The figure below shows a general flow diagram with the typical components present in an activated sludge wastewater treatment plant.

2025年2月1日 · Biologically stabilized sludge, known as “biosolids,” ensures a reduction in the organic fraction and the control of odor, vector attraction, and pathogens, thereby guaranteeing its safe disposal and minimizing severe environmental and public …

2019年12月11日 · Activated sludge process, which involves aerobic treatment of industrial effluents in stirred tank bioreactors, is one among the very old industrial applications of biotechnology. Still this process is popular in spite of some of its inherent limitations.

2024年3月20日 · Activated sludge is a widely applied and effective biological process in wastewater treatment plants which have dramatically improved worldwide despite an increase in population and urbanization.

2015年10月14日 · Activated sludge: it is the bacterial biomass inside the bioreactor that consists mostly of bacteria and other flora and microfauna. The sludge is a flocculent suspension of these microorganisms and is usually termed as the mixed liquor suspended solids (MLSS) that ranges between 2,000 and 5,000 mg L-1.

2024年9月9日 · Activated sludge has a high microbial diversity (bacteria, fungi, protozoa, and viruses). Some of these microbes are pathogenic and cause diseases for humans, animals, and plants, while others are non-pathogenic and contribute effectively to …

2022年1月1日 · Various biological and thermo-chemical treatment methods for sustainable management of sludge have been standardized for the same. This chapter discusses about sewage sludge and the...

2024年6月25日 · Biological wastewater treatment systems rely on beneficial bacteria and other microbes to decompose organic pollutants in wastewater into simple substances like carbon (IV) oxide (CO 2) and water (H 2 O) and generate biological floc or sludge; decomposition may occur aerobically or anaerobically .
