Mass transfer studies on biological denitrification in fluidized bed bioreactor.
A fluidized bed bioreactor has been used to carry out biological denitrification in the present work as it offers many advantages over other types of reactors. Plastic beads of low density (1055 kg/m3) were used as fluidizing media with Pseudomonas stuzeri, a denitrifying microorganism immobilized on them. The denitrification rate under different operating conditions was studied. The results of...
متن کاملComparison of ethanol, methanol and succinate effects as carbon sources on effluent biological denitrification
Abstract Background: Increase of nitrate concentration in water sources is becoming a serious problem in many parts of the world. Nitrogen containing compounds released into environment can create serious problems, such as eutrophication of water sources and hazard potential to human health, because it has potency of causing methemoglubinemia disease and cancer. Between recommended methods, bi...
متن کاملSonicated Sludge as Carbon Source for Denitrification
Ultrawaves sludge sonication technology was trialled at Maroochydore STP from February to June 2013. This was believed to be the first fullscale application of mechanical sludge lysis for enhanced denitrification in Australia. The results of the trial confirmed that sonicated waste activated sludge (WAS) could effectively replace the use of methanol as a carbon source for denitrification, and t...
متن کاملحذف نیترات از آب با استفاده از کنسرسیوم باکتریهای دنیتریفایر تثبیت شده بر روی کربن فعال در یک راکتور بستر شناور
Background : Nitrogen-containing ions such as nitrate and nitrite occur widely in a variety of water sources. This pollutant causes health problems such as the blue-baby syndrome, and possible formation of carcinogenic compounds in the digestive tract. Thus, removing them from water sources seems necessary. Biological denitrification is a method used in the treatment of nitrate contaminated wat...
متن کاملInvestigation of a Cold Model of Internally Circulating Fluidized Bed with Draft Tube to be used as a two-Zone Fluidized Bed Reactor
In this research, a cold model of internally circulating fluidized bed is investigated. The aim is to find the effects of some of the operating parameters on the performance of the reactor. Experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). The bed was loaded with white silica particles (dp = 0.15 -...
