Influence of polymer addition on granulation in upflow anaerobic sludge blanket reactor: A review
نویسندگان
چکیده
The upflow anaerobic sludge blanket (UASB) reactor has been used successfully treat a variety of wastewaters. The aim of this review is to synthesize and analyze information on how the process of granulation is affected by environmental and operational conditions in the reactor. The factors reviewed are strength of substrate, nutrients, multivalent cations and heavy metals, exocellular polymer, and addition of natural and synthetic polymers. Nature and strength of substrate in conjunction with intra-granular diffusion largely determines the microstructure of the granules. The addition of external additives as natural cationic polymers Chitosan as well as cationic fraction of Reetha (Sapindus trifoliata) extract, synthetic polymers "AA 184 H" may enhance granulation in the upflow anaerobic sludge blanket reactors.

Six upflow anaerobic sludge blanket (UASB) reactors were concurrently operated for 146 d to examine the effects of calcium on the sludge granulation process during start-up. Introduction of Ca at concentrations from 150 to 300mg/l enhanced the biomass accumulation and granulation process. The calcium concentration in the granules was nearly proportional to the calcium concentration in the feed,...
متن کاملon sludge granulation in UASB reactor
Impact of trivalent aluminium (Al) ion, added to the feed of upflow anaerobic sludge blanket (UASB) reactor, was assessed on the granulation of the reactor sludge. The impact on the reactor efficiency in treating chemical oxygen demand (COD) and generating biogas was also simultaneously assessed. It was seen that, at all the three Al concentrations (100, 200 & 300 mg/L) studied, the metal ion f...

The aim of this paper is to synthesize and analyze information on how the process of granulation is affected by environmental and operational conditions in the reactor. Various factors affecting granulation process as gleaned from the literature are organic loading rate (OLR), upflow velocity (Vup), sludge volume index (SVI), specific methenogenic activity (SMA), VSS/SS ratio, liquid in flow ra...
متن کاملRole of calcium (II) in anaerobic sludge granulation and UASB reactor operation: A method to develop calcium-fortified sludge outside the UASB reactors
Calcium is essential to the growth of several strains of microorganisms involved in anaerobic digestion. It has also been found to be effective in speeding up granulation of anaerobic sludges. But there are reports that the metal can exert a harmful effect on the performance of upflow anaerobic sludge blanket (UASB) reactor by causing the ‘cementing’ of some of the active sludge in the reactor,...
