Anaerobic, anoxic and aerobic environment can be simulated in the single stage sequential batch reactor (SBR) . Various design conditions viz., combinations of different phase time and different cycle time, hydraulic residence time (HRT), substrate loading rate, sludge age (SRT) and aeration time were analyzed for optimum biological treatment. The pilot runs were evaluated with the design conditions of food/microbe ratio (F/M) 0.2 per day and MLSS of 4950 mg/L. For the given design conditions 4, 5 and 6 hours cycle lengths were analyzed for their efficient performance with 30-33% of decant volume for sewage containing C:N:P of 100:8:2. Studies …


Competence Evaluation Of Mycodiesel Production By Oleaginous Fungal Strains: Mucor Circinelloides And Gliocladium Roseum, Sandip S. Magdum, Gauri P. Minde, Upendra S. Adhyapak, V. Kalyanraman Jul 2015

Competence Evaluation Of Mycodiesel Production By Oleaginous Fungal Strains: Mucor Circinelloides And Gliocladium Roseum, Sandip S. Magdum, Gauri P. Minde, Upendra S. Adhyapak, V. Kalyanraman

Comparing with lesser algal growth rate for biofuel production along with many constraints, fungal route should be analyzed for its capability of biodiesel or mycodiesel production. The two fungal strains namely, Mucor circinelloides (MTCC1297) and Gliocladium roseum (MTCC6474) were analyzed for laboratory scale mycodiesel production. The M. circinelloides and G. roseum were able to produce biomass of 0.404 mg VSS/mg sucrose and 0.642 mg VSS/ mg sucrose with the mycodiesel content of 20.69% (w/w) and 11.37% (w/w) respectively. Furthermore, qualitative analysis of the oil contents by GC-MS were identified the presence of Tetradecanoic and Octadecanoic acids.

Pilot plant studies of sequential batch reactor (SBR) cycles revealed the role of selector phase biology (SPB) involved in COD removal, nitrification, denitrification and total phosphate removal. The phases namely anoxic, anaerobic and aerobic in single tank reactor design of SBR were showed effective biological nutrient removal (BNR) > 90% on average in 4 h designed cycle time with 12 h of hydraulic retention time (HRT). The phases were 2 h fill which includes 1 h simultaneous fill and aeration, 1 h settle and 1 h decant. This cycle design found effective to create selective environment for microbes to carry biological …
