“…Reasons for the discrepancy between expectations and measurements are related to: (1) the complex nature of the wastewaters used in some experiments [12,16], (2) production of soluble microbial products (SMP)-from biomass decay and by substrate metabolism [2]-that was not taken into account [20,31], (3) an experimental set-up that did not provide good parameter identification [12,16,21,31] and (4) some experiments were performed only under thermophilic conditions. The experimental data obtained were compared to literature data of mesophilic conversions but these can also vary to a large extent, making the comparison rather difficult [5,7,8,12,20,31].…”

Kinetic parameters describing growth and decay of mesophilic (30 degrees C) and thermophilic (55 degrees C) aerobic biomass were determined in continuous and batch experiments by using oxygen uptake rate measurements. Biomass was cultivated on a single soluble substrate (acetate) in a mineral medium. The intrinsic maximum growth rate ( micro (max)) at 55 degrees C was 0.71+/-0.09 h(-1), which is 1.5 times higher than the micro (max) at 30 degrees C (0.48+/-0.11 h(-1)). The biomass decay rates increased from 0.004 h(-1) at 30 degrees C to 0.017 h(-1) at 55 degrees C. Monod constants were very low for both types of biomass: 9+/-2 mg chemical oxygen demand (COD) l(-1)at 30 degrees C and 3+/-2 mg COD l(-1)at 55 degrees C. Theoretical biomass yields were similar at 30 and 55 degrees C: 0.5 g biomass COD (g acetate COD)(-1). The observed biomass yields decreased under both temperature conditions as a function of the cell residence time. Under thermophilic conditions, this effect was more pronounced due to the higher decay rates, resulting in lower biomass production at 55 degrees C compared to 30 degrees C.

“…The existing measured values of four indicators were still higher than standards that existed more contaminants of pig meat, grease, hairs, urine, dunk, and blood in which some of them might be the bacteria inhibitors as described by Cauillard et al (1989) and Hammer (1989) and Hammer and Bastian (1989) Hammer (1989) Pattamapitoon (2013) Hadad et al (2006) and Tritt and Schuchardt (1992). In the same way, Hammer (1989) Pattamapitoon (2013) Hadad et al (2006) Palatsi et al (2011 and Tritt and Schuchardt (1992) concluded that there were uncertain condition to complete the bacterial organic digestion processes, it depends on solar radiation, air temperature, atmospheric moisture, washing water quality, organic properties, bacteria types, and topography.…”

“…The balancing condition is really needed to harvest the submerged aquatic plants by clear cutting of the zero-growth rate of the oldest plants with leaving the stem about 30-cm height, and to consume the herbivore fishestogetherwith zero-growth rate of biggest size (LERD 1999, Sklarz et al 2009, Molle et al 2008. The said concept has been shown in success of organic wastewater treatment under the biological processing principles through both the vertical and horizontal flow constructed wetlands (VFCW and HFCW) as evidenced from the previous researches (Soroko 2007, Cauillard et al 1989, Kayser and Hunst 2005, Ahn and Mitsch 2002, Hammer and Bastian 1989, Hammer 1989, Boyd 1970, Khan et al 2009, Juwarkar et al 1995, Stottmeister et al 2003, Cui et al 2010. The wastewater treatment efficiencies were varied from 85 % to 95 % for COD, BOD, TDS, SS, DOC, DOP, DON, NH3-N, color, coliform and fecal bacteria; 80 % to 90 % for sulfate, TKN, EC, alkalinity, acidity, and organic compounds (Boyd 1970, Khan et al 2009, Juwarkar et al 1995, Main et al 2006, Nopparatanaporn 1992, Molle et al 2008 Sklarz et al 2009).…”

Oxidation Pond (OP) as engineering tool is generally used for treating the pig slaughterhouse wastewater which normally contains high concentration of COD and BOD in effluent. Unfortunately, it cannot reduce the organic substance (blood, hairs, grease, meats, solid dunks and some contaminants) from pig slaughtering areas under the 2-consecutive oxidation ponds by producing the minimum values of COD 151.92 mg/L, BOD 79.14 mg/L, coliform bacteria 2.6 x 10 -5 MPN/100mL, and fecal bacteria 1.5 x 10 -5 MPN/100mL but all of them above the standard values. After treating the effluent by VFCW-Typha from the 2-consecutive oxidation ponds, the results found COD 90.92 mg/L, BOD 31.67 mg/L, coliform bacteria 1.5 x 10 -4 MPN/100mL and fecal bacteria 2.0 x 10 -3 MPN/100 mL which were almost above the standard values. It is noted that the modification of 2-m consecutive ponds to 4-m consecutive ponds in cooperating the prolongation of VFCW-Typha length instead of 30 meters to 40-50 meters, width 3-5 meters, and still keeping 1-m depth would be enough to support the pig-slaughterhouse wastewater treatment system.Summarily speaking, the experimental results have been brought to say that the Oxidation Pond as the engineering tool could not be applicable in slaughterhouse wastewater treatment that containing high concentration COD and BOD from slaughtering and dissecting activities.

RESUMOOs processos de oxidação avançada (POAs) têm surgido como métodos eficazes para o tratamento terciário de efluentes industriais porque eles são capazes de destruir os poluentes e não apenas transferí-los de uma fase para outra como ocorre nos processos terciários convencionais aplicados em indústrias frigoríficas. O processo biológico, tratamento principal utilizado para efluentes frigoríficos, é limitado à degradação de substâncias biodegradáveis e que não são tóxicas para a cultura biológica. A utilização de um processo integrado FentonCoagulação para o tratamento terciário desses efluentes aparece como uma alternativa promissora e, portanto, o objetivo do presente trabalho foi determinar as condições operacionais do processo proposto para o tratamento terciário de efluente frigorífico. As variáveis investigadas foram a razão [Fe +2 ]/[H 2 O 2 ] e pH COAGULAÇÃO . Os ensaios foram conduzidos em triplicata de acordo com um delineamento central composto rotacional (DCCR) 2 2 , com três pontos centrais e quatro pontos axiais, que totalizou 11 ensaios. A eficiência do processo proposto foi determinada em cada ensaio experimental em função da eficiência de remoção da demanda química de oxigênio (DQO). Na faixa investigada, as condições operacionais definidas foram razão [Fe +2 ]/[H 2 O 2 ] de 0,800 e o pH COAGULAÇÃO de 5,50. O estudo revelou que o processo integrado Fenton-Coagulação proposto conduzido nas condições definidas alcançou uma eficiência de remoção de DQO superior a 71%, e pode, portanto, ser usado para o tratamento terciário de efluente frigorífico com o objetivo de degradação de matéria orgânica recalcitrante (não biodegradável).Palavras-chave: degradação, matéria orgânica, processos de oxidação avançada. Determination of operational conditions for tertiary treatment of slaughterhouse wastewater by the integrated Fenton-Coagulation process ABSTRACTAdvanced oxidation processes (AOPs) appear to be effective methods for tertiary wastewater treatment because they are able to destroy pollutants and not only transfer them from one phase to another without destroying them as is the case with conventional tertiary processes applied in the slaughterhouse industries. Biological processes are the main
