“…Consequently, they are discharged to surface water and groundwater through household and industrial wastewaters [13]. They also cause foam in rivers and effluent treatment plants and reduce water quality, and also cause short-and longterm damage to the environment [14][15][16]. Surfactants are harmful for fish and human beings [14] -for instance LAS in low concentrations (i.e., 1 mgL -1 can poison aquatic organisms) [17].…”

The aim of our study was to investigate the effectiveness of Fenton and photo-Fenton processes for removing anionic surfactants from aqueous solutions. The study was conducted using 200 mgL and 120 mgL -1 ferrous ion) were 69.38 and 86.66%, respectively, which is consistent with the significant increase in the rate of LAS removal efficiency with reaction time (P<0.05). In conclusion, anionic surfactants removal was significantly correlated with reaction time by both methods, but showed less dependence on H 2 O 2 and Fe 2+ concentrations.

“…Surfactants cause short-term as well as long-term changes in the ecosystem; they are harmful to humans, fishes and vegetation. Subsequently, many environmental and public health regulatory authorities have fixed stringent limits for anionic detergent as standard 0.5 mg/L for drinking water and 1.0 mg/L for other purposes [13].…”

A Critical Review on Processes and Energy Profile of the Australian Meat Processing Industry

This review article addresses wastewater treatment methods in the red meat processing industry. The focus is on conventional chemicals currently in use for abattoir wastewater treatment and energy related aspects. In addition, this article discusses the use of cleaning and sanitizing agents at the meat processing facilities and their effect on decision making in regard to selecting the treatment methods. This study shows that cleaning chemicals are currently used at a concentration of 2% to 3% which will further be diluted with the bulk wastewater. For example, for an abattoir that produces 3500 m 3 /day wastewater and uses around 200 L (3%) acid and alkaline chemicals, the final concentration of these chemical will be around 0.00017%. For this reason, the effects of these chemicals on the treatment method and the environment are very limited. Chemical treatment is highly efficient in removing soluble and colloidal particles from the red meat processing industry wastewater. Actually, it is shown that, if chemical treatment has been applied, then biological treatment can only be included for the treatment of the solid waste by-product and/or for production of bioenergy. Chemical treatment is recommended in all cases and especially when the wastewater is required to be reused or released to water streams. This study also shows that energy consumption for chemical treatment units is insignificant while efficient compared to other physical or biological units. A combination of a main (ferric chloride) and an aid coagulant has shown to be efficient and cost-effective in treating abattoir wastewater. The cost of using this combination per cubic meter wastewater treated is 0.055 USD/m 3 compared to 0.11 USD/m 3 for alum and the amount of sludge produced is 77% less than that produced by alum. In addition, the residues of these chemicals in the wastewater and the sludge have a positive or no impact on biological processes. Energy consumption from a small wastewater treatment plant (WWTP) installed to recycle wastewater for a meet facility can be around $500,000.

“…A presença destes compostos em estações de tratamentos de efluentes causa um decréscimo na eficiência da etapa biológica, pelo efeito tóxico e formação de espumas e também nos processos físico-químicos, pois reduz a capacidade de floculação e consequentemente a sedimentação de sólidos presentes nos efluentes (Aboulhassan et al, 2006;Mungray e Kumar, 2008;Taffarel e Rúbio, 2010). Foi também reportado que, em estações de tratamento anaeróbio, os surfactantes são inibidores severos da digestão, sendo removidos somente com baixa eficiência (Gavalla, 2002).…”

RESUMO -A preparação de adsorventes economicamente viáveis a partir de precursores oriundos de resíduos industriais tem sido avaliada no intuito de otimizar o processo de adsorção. Desta forma, os resíduos da avicultura foram utilizados para produção de carvões ativados com ácido fosfórico, analisando-se a influência da temperatura de carbonização, concentração de ácido fosfórico e tempo de ativação. INTRODUÇÃOO desenvolvimento econômico tem impulsionado o crescimento do setor industrial e tecnológico, consumindo recursos naturais e comprometendo os sistemas hídricos devido à introdução de poluentes como surfactantes, metais pesados e compostos organoclorados, o que reduz a disponibilidade de água potável e aumenta os custos no processo de tratamento (Pinheiro Filho, 2008).Os surfactantes em águas de abastecimento e efluentes são um problema ambiental, devido a formação de espumas e consequente redução na transferência de oxigênio à biota aquática, além de concentrações acima de 1 mg.L -1 causarem efeitos tóxicos a mesma. A presença destes compostos em estações de tratamentos de efluentes causa um decréscimo na eficiência da etapa biológica, pelo efeito tóxico e formação de espumas e também nos processos físico-químicos, pois reduz a capacidade de floculação e consequentemente a sedimentação de sólidos presentes nos efluentes (Aboulhassan et al., 2006; Mungray e Kumar, 2008; Taffarel e Rúbio, 2010). Foi também reportado que, em estações de tratamento anaeróbio, os surfactantes são inibidores severos da digestão, sendo removidos somente com baixa eficiência (Gavalla, 2002).
