Beef Slaughterhouse
Problem: A beef slaughterhouse in Idaho wanted to compare performance and efficiency between their existing DAF unit and the HydroCal CAF flotation unit. Solution The Hydrocal CAF ran continuously for 8-10 hours per day. Test runs were made with and without polymer and samples were collected over a wide range of feed conditions. Within one hour of start up, a thick float was obtained without ...

The role of education and training levels of slaughterhouse workers in the cross-contamination of carcasses
Meat products are frequently implicated in foodborne diseases. The hygienic status of dressed carcasses is largely dependent upon the general slaughterhouse hygiene and the skills of the workers. Training, knowledge of food safety issues and communication skills of slaughterhouse workers were evaluated to identify their role in the contamination of carcasses. Face-to-face interviews were ...

Factors affecting phosphorus exports from sites irrigated with abattoir wastewater
Abattoir wastewaters often contain significant quantities of phosphorus, inorganic salts, nitrogen and biodegradable organic materials. The nutrients in abattoir wastewaters are potentially useful for plant production and in many countries the application of abattoir wastewaters to land is considered a preferable option to other forms of treatment. In this paper we investigate the factors that ...

US feedlots and slaughterhouses: bounding industrial ecology with the extreme case
The potential contribution of Industrial Ecology (IE) to sustainable development, though immense, remains elusive. This is due to the field boundaries whose demarcation lacks specificity. To address the challenge of boundary definition, an agro-industrial complex, the US Cattle Feedlot-Slaughterhouse System (CFSS), has been chosen to illustrate and provoke a discussion about where those ...

The potential of ultrasonic membrane anaerobic systems in treating slaughterhouse wastewater
Direct discharge of slaughterhouse wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD), total suspended solids (TSS) and biochemical oxygen demand. In this study, an ultrasonic-assisted membrane anaerobic system was used as a novel method for treating slaughterhouse wastewater. Six steady states were achieved, using concentrations of 7,800–13,620 ...

Air as a source of bacterial contamination in a slaughterhouse prior to implementation of hygienic control systems
The shelf-life, quality and safety of meat can be reduced by bacterial contamination. The limited study of airborne bacteria often means that their impact is overlooked. This research assessed the role of airborne bacteria in the contamination of carcasses during processing in a slaughterhouse prior to implementing hazard analysis and critical control point (HACCP). Aerosolised bacterial counts ...

Reusing date seed residues as a low cost adsorbent for slaughterhouse wastewater purification
Date seeds were found to be as effective adsorbents as activated carbon for the removal of organics from slaughterhouse wastewater. Experiments were successfully employed to attain the maximum amount of COD adsorption. The maximum adsorption capacity were 53 and 60 mg/g for date seeds and activated carbon, respectively. In view of the stringent water quality requirements, adsorption using date ...

Slaughterhouse carcass waste composting case study
Slaughterhouse waste was treated with BactiDomus Technology compost accelerator to monitor the effects of the treatment against untreated waste. The goal of the project is to increase the efficiency of the composting process to reduce the total time needed to turn the waste into compost. Two separate bins of waste were treated with BactiDomus Technology compost accelerator, the first on August ...

Slaughterhouse case study
Slaughterhouse in Ireland, part of an international group, found themselves unable to comply with their effluent discharge consent levels following the introduction of legislation adopting EU Environmental Directives. The slaughterhouse, on average, processes 200 sheep per day. The plant produces an effluent flow of approximately 200 m3/day and this, after treatment, is discharged into a river. ...

Anodic oxidation of slaughterhouse wastewater on boron-doped diamond: process variables effect
A non-sacrificial boron-doped diamond electrode was prepared in the laboratory and used as a novel anode for electrochemical oxidation of poultry slaughterhouse wastewater. This wastewater poses environmental threats as it is characterized by a high content of recalcitrant organics. The influence of several process variables, applied current density, initial pH, supporting electrolyte nature, ...

Chicken slaughterhouse
Country: U.S. Problem: Poor final effluent quality Product: BFL 5100HP Background A chicken slaughterhouse was killing 10,000 chickens per day. Final effluent was discharged to a stream. The final effluent COD was exceeding the discharge limit of 100mg/L and as a result it had to be tankered off site and spread on agricultural land. Obviously this was costly and not sustainable as a medium to ...

Testimonial Mr. Boode, The Netherlands: So much better in every aspect
Erik Boode from Markelo in the Netherlands were to build his third house, but wanted a better performing ventilation system. In his search he came across the ventilation system developed by DACS. In my DACS house it is quite different I have two houses, each with a traditional negative pressure ventilation system from a well-known manufacturer here in the Netherlands. I spend much time trying to ...

Pork Slaughterhouse - Case Study
Introduction Prior to the installation of two 1,200 gpm GEM (Gas Energy Mixing) Systems, CWT’s Client discharged approximately 1.9 million gallons per day (mgd) to their onsite pretreatment plant consisting of an Infilco Dissolved Air Flotation (DAF) unit service with a Nikuni pump, and a Maxair Clarifier (DAF) for further removal of contaminants. Float from both units was heated and sent ...
