The South African poultry industry has grown exponentially in recent years due to an increased demand for their products. As a result, plants consume large volumes of high quality water ensure that hygienically safe products are produced. Furthermore, industries generate strength wastewater, which can be treated successfully at low cost using anaerobic digesters. In this study, the performance bench-scale mesophilic static granular bed reactor (SGBR) containing fully granules coupled with...
Abstract The first step towards selecting a suitable treatment option for poultry slaughterhouse wastewater (PSW) is to characterize it. Various parameters such as the pH, tCOD, BOD5, TSS, FOG, turbidity, salinity or conductivity were analyzed in this study and provided values significantly higher than discharge limits imposed by various countries. Furthermore, biodegradability index (BOD5/COD) of PSW was determined averaged value 0.61 samples collected during normal processing operations...
Abstract Poultry slaughterhouses consume a substantial quantity of potable water during processing live birds. Subsequently, high strength poultry slaughterhouse wastewater (PSW) is generated at different stages product processing. In this study, Static Granular Bed Reactor (SGBR) was used to treat the PSW from facility in Western Cape, South Africa. The performance SGBR primarily evaluated for chemical oxygen demand (tCOD) removal with kinetics treatment process being using both Grau...
This study presents the biological treatment of poultry slaughterhouse wastewater (PSW) using a combination pretreatment stage, an expanded granular sludge bed reactor (EGSB), and membrane bioreactor (MBR) to treat PSW. PSW was geared toward reducing concentration contaminants present in meet City Cape Town (CoCT) discharge standards evaluate alternative means treating medium- high-strength at low cost. The EGSB used this operated under mesophilic conditions organic loading rate (OLR) 69 456...
Abstract The poultry slaughterhouse industry consumes a large volume of potable water for bird processing and equipment cleaning, which culminates in the generation high strength wastewater (PSW). contains concentrations organic matter, suspended solids, nitrogen nutrients. Most slaughterhouses South Africa (SA) discharge their into municipal sewer system after primary treatment. Due to its strength, PSW does not meet SA's industrial standards. Discharge untreated environment raises...
Abstract This study evaluated the performance of a novel high rate anaerobic bioreactor system for treatment poultry slaughterhouse wastewater (PSW). The new consisted granule-based technology operated in down-flow configuration, with assistance medium-sized pumice stones used as packing materials retention granules, to avoid challenges associated use three-phase separator up-flow systems and washout biomass. Furthermore, recycling stream was applied improve mixing inside Down-flow Expanded...
This paper assesses the performance of an integrated multistage laboratory-scale plant, for treatment poultry slaughterhouse wastewater (PSW). The system was comprised eco-flush dosed bio-physico pre-treatment unit fats, oil, and grease (FOG) hydrolysis prior to PSW being fed a down-flow expanded granular bed reactor (DEGBR), coupled membrane bioreactor (DEGBR-MBR). system’s configuration strategy developed achieve optimal by introducing enzymatic lipid-rich influent (PSW) in order treat FOG...
In this study, the efficiency of an anaerobic treatment system for wastewater from a South African poultry slaughterhouse was evaluated using lab-scale static granular bed reactor (SGBR). The down-flow SGBR (2 L) operated continuously 138 days under mesophilic conditions (35-37 ˚C), at hydraulic retention times (HRTs) ranging 24 to 96 h and average organic loading rates (OLRs) 0.78 5.74 g COD/L.day. achieved chemical oxygen demand (COD) removal 80% maximum COD 95%, HRT OLR optimization SGBR,...
Poultry slaughterhouse wastewater contains high concentrations of chemical oxygen demand (COD), total suspended solids (TSSs), fats, oil and grease (FOG), proteins carbohydrates. It is important that the treated to acceptable environmental discharge standards. In this study, poultry (PSW) was using two-stage processes consisting a biological pre-treatment biodegrading agent (Eco-flushTM) coupled with down-flow expanded granular bed reactor (DEGBR). The results showed observed be highly...
The treatment of poultry slaughterhouse wastewater (PSW) with an Expanded Granular Sludge-Bed Bioreactor (EGSB) is hindered by the washout activated sludge, and difficulties associated operation three-phase separator determination optimum up-flow velocity for sludge-bed fluidization. This results in a poor reactor functionality, thus performance due to pollutants such as fats, oil grease (FOG) PSW being treated. Hydrolyzing FOG content bio-delipidation, enzyme-based agent pre-treatment unit...
The poultry industry generates significant volumes of slaughterhouse wastewater, laden with numerous pollutants, thus requiring pretreatment prior to discharge. However, new technologies must be used re-engineer the existing wastewater treatment equipment and incorporate designs improve processes or system performance. In this study, three variables, i.e., diffuser design, bioflocculant form, flow rate, were evaluated determine their effect on performance a bioflocculant-supported column...
This study determined whether it is feasible to pretreat mixed agro-waste of different particle sizes using the pitcher fluid Nepenthes mirabilis (N. mirabilis), which known digest leaf litter due enzyme cocktail contained in fluid. need for holocellulolysis (a source fermentable sugars) produce hydrolysates. The was fractionated (<3 kDa, >3 <10 >10 kDa) and slurrified with agro-waste, i.e., 25% (w/w) each waste—orange peels, apple maize cobs, grape pomace, oak plant various...
Pathogenic organisms in dairy products like yoghurt have for several years been a matter of public health concern. An investigation on the microbiological quality 12 commercial samples gotten from four different brands designated A, B, C and D respectively were analysed using poor plate method to determine their respective microbial qualities. Samples randomly obtained locations Bamenda data ANOVA. Results enumeration showed that all recorded 0.0x101 cfu/ml,E coli counts. The total viable...
