Повний текст джерелаGrease traps are devices that retain animal and vegetal fatty material from kitchen sinks. Many municipalities demand its installation in order to connect house wastewater to the public network, aiming to reduce fat, oil and grease concentration in the collecting and treatment systems. The establishment of maintenance schedule involving inspection and periodic cleaning is a key factor to the right functioning of the device. The existence of appropriated sites to receive and pretreat grease trap wastes may stimulate good practices on maintenance and operation of these devices. In this direction, the objectives of this research are the characterization of grease trap wastes and the evaluation of flotation as an alternative for its pretreatment, followed by characterization of the oil extracted from the scum formed at flotator. Therefore, grease trap wastes from different sources were collected and characterized. It could be observed a wide variation on its composition and high concentrations of BOD, COD, TSS and FOG. Lab scale tests were performed to assess flotation performance to reduce pretreated effluent FOG using four chemical coagulants: PAC, ferric chloride, tannin and cationic polymer. All of them achieved high efficiency on FOG removal, however the product that presented more advantages on application was polymer. More tests were performed using several dosages of polymer associated to three pH coagulation conditions. The combination that resulted in the best efficiency was 30 mg/L of polymer combined to pH 4.3, samples natural pH. Different A/S ratios were also tested (7.5/1000, 15/1000, 22/1000 gair/gsolids), the ratio 22/1000 gair/gsolids presented the best FOG removal efficiencies. Floated material from A/S ratio tests were characterized and presented TS concentrations between 9.7% and 10.6% and FOG was from 6.1% to 6.7%. Based on the obtained results, flotation appears as a high performance alternative for the pretreatment of studied wastes. A pilot plant was operated to evaluate problems related to grease trap waste handling. The main problems were: bad odor, the need of screening and waste homogenization in equalization tank. Aiming to reuse the floated waste, oil was extracted from a sample (8.86% solid content) using solvent, achieving the recovery of 30g oil/L waste with 13.76 mgKOH/L acidity. The high acidity points to the need of purification if biodiesel production is intended.

Повний текст джерелаPrevious studies show that problems with fat in the municipal sewer systems are increasing. The fat that ends up in the drain leads to costs related to operation and maintenance, as well as issues with reaching the laws and rules that the owners of the water- and wastewater infrastructure needs to apply. What are the sewer system owners doing against this problem? Is the use of biotechnology a part of the solution? What actions are available towards the households? In this study we have done a literature study about fat in sewers, a survey to investigate the publics knowledge about food waste separation. We have also performed interviews with companies within the field. The results from the survey shows indications that the information to the public can be improved. The accessible information aimed towards the public on the municipality's website is hard to reach. Fat in sewers is often an invisible problem to the individuals. Because of this efforts with information is needed to lower the emergence of fat. The use of grease traps is an effective solution if they are correctly dimensioned and are emptied every month. The effect that biotechnology have on the wastewater system ought to be investigated in a larger study.

Повний текст джерелаThe effluent from the kitchen sink, dishwasher, tank/washing machine, toilet bowl, shower, sink and tub when not covered are the source of many environmental problems and public health. The current management models based on conventional technologies still present technical and economic limitations. In this context, the study aimed to develop and propose a new model of management of domestic sewage and specifically the development of an alternative technology for the preliminary treatment of wastewater generated in the kitchen sink (due to its specific characteristics). The methodology included the qualitative and quantitative characterization of the generating source and domestic effluents, methods of collection, transportation and conventional treatment of domestic sewage and explanation of the advantages/disadvantages of the methods, processes and conventional technology. The results of the monitoring activities and habits of a family allowed determining the water consumption and the consequent generation of waste in each of the sources, which resulted in a correlation that will assist in the calculation of generation capacity/production of domestic sewage in homes and corresponding diagnosis. The tests performed with commercially available technologies for treating the effluent from the kitchen sink (grease trap) have identified the technical limitations of these technologies and the consequence was that the development of a new technology with innovative features called "ash for treatment of effluent from the sink kitchen with simultaneous separation of fat and settleable solids - Model UNIOESTE" innovative technology and in the process of patenting. It therefore contributes to mitigating the negative impacts that result from inadequate management of domestic wastewater using for such technological innovations resulting from intellectual activity with experimental validation. Key-words: domestic sewage, effluent from the kitchen sink, waste management, grease trap.
Os efluentes domésticos provenientes da pia da cozinha, máquina de lavar louça, tanque/máquina de lavar roupas, bacia sanitária, chuveiro, lavatório e banheira quando não tratados são fonte de muitos problemas ambientais e de saúde pública. Os atuais modelos de gestão com base de tecnologias convencionais ainda apresentam limitações técnicas e econômicas. Nesse contexto, o trabalho objetivou o desenvolvimento e proposição de um novo modelo de gestão de efluentes domésticos e especificamente o desenvolvimento de uma tecnologia alternativa para o tratamento preliminar do efluente gerado na pia da cozinha (devido às suas características peculiares). A metodologia contemplou a caracterização qualitativa e quantitativa da fonte geradora e dos efluentes domésticos, dos métodos de coleta, transporte e tratamento convencional de efluentes domésticos e explicitação das vantagens/desvantagens dos métodos, processos e da tecnologia convencional. Os resultados do monitoramento das atividades e hábitos de uma família permitiram determinar o consumo de água e a conseqüente geração de efluentes em cada uma das fontes, cujo resultado foi uma correlação que deverá auxiliar no cálculo da capacidade de geração/produção de efluentes domésticos nas residências e o correspondente diagnóstico. Os testes realizados com tecnologias disponíveis no mercado para tratamento do efluente da pia da cozinha (caixa de gordura) permitiram identificar as limitações técnicas dessas tecnologias e a conseqüência disso foi o desenvolvimento de uma nova tecnologia com características inovadoras denominada Caixa para tratamento de efluente da pia da cozinha com separação simultânea de gordura e sólidos sedimentáveis Modelo UNIOESTE , de tecnologia inovadora e em fase de patenteamento. Desta forma, contribui-se com a mitigação dos impactos negativos que resultam da gestão inadequada dos efluentes domésticos utilizando-se para tal, inovações tecnológicas resultantes da atividade intelectual com validação experimental.
