INFLUENCE OF SEED LOADS ON START UP OF MODIFIED ANAEROBIC HYBRID BAFFLED (MAHB) REACTOR TREATING RECYCLED PAPER WASTEWATER
Journal Title: Engineering Heritage Journal (GWK) - Year 2017, Vol 1, Issue 2
Abstract
The startup and performance of 58 L modified anaerobic hybrid baffled (MAHB) reactor operated under mesophilic conditions (35 ̊C) were investigated. The performance data of MAHB reactor and its influence of seed loads and start up process with regards to chemical oxygen demand (COD) removal by using various seed arrangement are compared. Three different seed loads were evaluated. Similar start up strategies were adopted in all systems, using a constant hydraulic retention time (HRT) of 4 days and influent chemical oxygen demand (COD) concentration of 750 mg/L. This present study was done to compare the result for COD removal, pH, methane concentration, and solid content in terms of volatile suspended solids (VSS) at three different start up. Start up 3 shows better reactor performance with highest COD removal (87%), stable system pH, and higher methane content (>65%). At the end of experiment, methanogen bacteria were observed in the MAHB reactor using autofluorescene microscope and scanning electron microscope (SEM) identification. Population of most probably Methanosarcina, Methanasaeta and Methanobacterium were present in the MAHB reactor which are responsible to produce methane in the system.
