Category 2 animal by-products that need to be sterilized with steam pressure according Regulation (EC) 1774/2002 are studied. In this work, 2 sets of experiments were performed in mesophilic conditions: (i) biomethane potential determination testing 0.5%, 2.0% and 5.0% total solids (TS), using sludge from the anaerobic digester of a wastewater treatment plant as inoculum; (ii) biodegradability ...

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 ...

The feasibility of a biological (EcoflushTM) and/or electrocoagulation (EC) treatment system in removing chemical oxygen demand (COD) and fats, oils, grease (FOG) from poultry slaughterhouse wastewater (PSW) were studied. response surface methodology (RSM) was used to identify the optimum operating condition for EC its integration with EcoflushTM as pre-treatment removal lipids. conditions obta...

nemone tehran poultry slaughterhouse with an area of 13000 m2 is located in region 3 of district 5 of tehran municipality, in the morad abad quarter. the current research aimed to assess environmental impacts caused by the slaughterhouse operations. to do this, the methods scaling-weighting checklist and analytic hierarchy process (ahp) were integrated. the required criteria and potential optio...

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) ...
