Treatment of meat industry wastewater using dissolved air flotation and advanced oxidation processes monitored by GC–MS and LC–MS

Slaughterhouse wastewater characteristics, treatment, and management in the meat processing industry: A review on trends and advances

“…According to Table 1, the meat processing industry is one of the major consumers of freshwater among food and beverage processing facilities, which makes slaughterhouses a significant producer of wastewater effluents (De Sena et al, 2009). The World Bank Group (2007) classifies a slaughterhouse plant as a meat processing facility that may consume between 2.5 and 40 m 3 of water per metric tons of meat produced.…”

Applying electro-Fenton process as an alternative to a slaughterhouse effluent treatment

“…In all cases the cathode was carbon felt (CF). There are studies of the treatment of similar wastewater, using processes based on free radicals • OH, such as the one reported by de Sena et al [27], in which the result for a combined treatment with the photo Fenton process was a total removal for chemical oxygen demand of 97.6%.…”

Production of fuel from the catalytic cracking of pyrolyzed poultry DAF skimmings

“…After the removal of organic material using DAF, wastewater can then be treated in conventional wastewater treatment systems. As an alternative, Sena et al [1] showed that DAF processing followed by an advanced oxidation process could effectively generate an effluent with organic loads acceptable for discharge. However, the issue of what to do with DAF solid waste still remains.…”
