“…A marked improvement has been noticed for higher percentage removal of COD during increase of aeration time. A similar observation was noticed by Kanimozhi and Vasudevan [41]. Due to the increase of time and COD load more cells to be produced eventually higher degree of organic removal.…”

Slaughterhouse wastewater contains diluted blood, protein, fat, and suspended solids, as a result the organic and nutrient concentration in this wastewater is vary high and the residues are partially solubilized, leading to a highly contaminating effect in riverbeds and other water bodies if the same is let off untreated. The performance of a laboratory-scale Sequencing Batch Reactor (SBR) has been investigated in aerobic-anoxic sequential mode for simultaneous removal of organic carbon and nitrogen from slaughterhouse wastewater. The reactor was operated under three different variations of aerobic-anoxic sequence, namely, (4+4), (5+3), and (3+5) hr. of total react period with two different sets of influent soluble COD (SCOD) and ammonia nitrogen (NH4 +-N) level 1000 ± 50 mg/L, and 90 ± 10 mg/L, 1000 ± 50 mg/L and 180 ± 10 mg/L, respectively. It was observed that from 86 to 95% of SCOD removal is accomplished at the end of 8.0 hr of total react period. In case of (4+4) aerobic-anoxic operating cycle, a reasonable degree of nitrification 90.12 and 74.75% corresponding to initial NH4 +-N value of 96.58 and 176.85 mg/L, respectively, were achieved. The biokinetic coefficients (k, K s, Y, k d) were also determined for performance evaluation of SBR for scaling full-scale reactor in future operation.

“…With the change of OLR removal efficiency also affected, at the lower OLR removal efficiency was high. Increasing OLR gave an increased substrate concentration and elevated microbial growth resulting high COD removal rate (Kanimozhi and Vasudevan, 2014). However, further increased in the OLR dropped the removal efficiency.…”

Abstract. The performance and the characteristics of a laboratory-scale ABR (anaerobic baffled reactor) were investigated during different seasons (summer, spring, autumn and winter). ABR successfully achieved COD removal efficiencies 74% during summer, 68% during autumn/spring and 62% during winter. Compartment I, II and III showed high removal rate of COD during whole study period. At lower OLR (organic loading rate), COD removal rate was high. The analysis of biogas production during all seasons showed downward trend with increase of HRTs (hydraulic retention time). Compartment I showed high VFA (volatile fatty acid) synthesis compared to others compartments. The ABR has the potential to provide a greater efficiency and be applicable for all type of seasons and temperature conditions.

“…In the past 20 years, several research groups have conducted studies to purify, use, or dispose of vinasses (Dura´n-de-Baz´ua et al, 1991;Kanimozhi and Vasudevan, 2014;Maiorella et al, 1983;Strong and Burgess, 2008a). Biological treatment is the most commonly used because of its low operating costs, and biodegradation (mineralization) of a large number of organic compounds present in effluents related to mezcal vinasses.…”

In Mexico, mezcal production generates huge amounts of vinasses (MV) that cause negative environmental impacts. Thus, MV treatment is necessary before discharge to water bodies. Although there is no information for mezcal vinasses, similar effluents have been treated by biological processes (i.e. anaerobic and aerobic) usually complemented by oxidative chemical pretreatments (ozonation) and physico-chemical methods. In this work MV were first ozonated and followed by batch aerobic biological degradation. In the ozonation stage, organic matter removals were 4.5-11 % as COD, whereas the removal of aromatic compounds and phenols were 16-32 % and 48-83 % respectively. In the aerobic post-treatment, COD depletions up to 85 % were achieved; removals in ozone pre-treated vinasses were higher (80 to 85 %) than that of raw vinasse (69 %). It seems that ozonation preferentially attacked the recalcitrant fraction of organic matter present in the vinasses and increased its aerobic biodegradability.
