removing fats, oils, & grease (fog) not only helps with floating solids, it also helps lower cod/bod, foaming - and even helps improve sludge dewatering characteristics (less water entrained). ways to prevent fog from entering a biological treatment unit:
in order to enhance the biodegradability of the excess sludge generated from the wastewater treatment, a centrifugal vibration mill was used to mill the activated sludge. the centrifugal vibration mill had a column with a volume of about 10 × 10-3 m3 and the sphere
· pdf vibrating ball mill (milling system) the wastewater treatment test method was the same as the control system described above, except that the activated sludge reactor included a vibration milling process. of the discharged sludge, 75% was milled using a batch
rapid oxidative degradation can be used for the direct disposal of sludge waste or pretreatment before the dehydration step. methods for reducing oil content of sludge for mechanical treatment of the sludge, a sonicator, a ball mill, and a homogeniser were used
aerobic treatment alone is not viable because the oxidation ponds, as well as high energy consumption for aeration, cooling system are required. furthermore, anaerobic stage needs no oxygen to operate, whereas anoxic stage can only be operated in the presence of oxygen ( vincenzo and luigi, 2012 ).
the activated sludge system is an effective biological treatment applied widely in both industrial and municipal wastewater treatment facilities worldwide. yet, the big issue arising from this process is the huge amount of sludge production at the end of the process.
