A pilot study was performed over 91 days to determine if the activated sludge process could treat a segregated stripped sour water (SSW) stream from a petroleum refinery. The study was performed in two periods. The first period was terminated after 19 days due to excessive sludge bulking.

activated sludge microbes and converted to biomass, water, carbon dioxide, and other gases • Nitrification – The process through which ammonia is oxidized to nitrite and nitrate • Denitrification – A process by which nitrates and nitrites are converted to gaseous end products, primarily nitrogen gas.
F:M = (8.34* S o* Q o)/ (8.34* %Vol * X * V MG) The table at the right shows the typical range of values for the three activated sludge aeration tank design parameters, volumetric loading, hydraulic retention time, and food to microorganism ratio.
Dec 28, 2000 · To design such a process, however, careful consideration must be given to all of the following parameters. Oxygen Requirements When thickened sludges are fed to the aerobic digester, the oxygen uptake rate in the first part of the digester is extremely high, with as much as 70% of the total oxygen requirement needed in the first ten days.
Biological Activated Carbon process is developed on the basis of activated carbon technology, which uses from environment like soil, activated sludge, underground water, rivers, lakes and Therefore, by calculating the oxygen consumption rate in the process of treating organics by BAC and BCF...The Development of Nereda® A public-private research partnership in the Netherlands between the world-renowned Delft University of Technology, research institutes, water authorities and Royal HaskoningDHV led to the invention of the first technology applying Aerobic Granular Sludge Technology for the biological treatment of wastewater.
Some of the major process of secondary or biological treatment are as follows: (i) Activated Sludge Process (ii) Trickling Filters. The biological process of sewage is a secondary treatment involving removing, stabilizing and rendering harmless very fine suspended matter, and solids of the wastewater that remain even after the primary treatment has been done.

Oxygen Conventional activated sludge is an aerobic process. Many bacteria in the activated sludge process need free oxygen (O2) to convert food into energy for their growth. For optimal performance, it is very important for an operator to be sure enough oxygen is being provided in the aeration tanks for the microorganisms (typically 1.0-3.0 mg/L).
