Metodika návrhu systému využití šedých vod ve vybraných objektech / Methodology of use greywater in the selected objects

Raček, Jakub Unknown Date (has links)
The concept of reusing wastewater in buildings has recently become more important. This is due to change in climatic conditions and reduction of the yield of water resources. Greywater can broadly be defined as not extremely polluted wastewater coming from basins, showers, baths, kitchen sinks and washing machines. The concept based on the use of alternative rate sources wouldn't need same strict parameters as drinking water. Dissertation engage in collecting greywater from basins, showers and wash machines separately from the other more polluted domestic wastewater at the dorms, the laundry machines, the hotels, detached houses, the swimming pools, the office buildings and other buildings. The research showed that membrane filtration meets all needed parameters of water quality and can be used in house systems where we use cleansed white water to flush toilets, watering garden or grass areas. There is still a lack of experience and documentation for such system of operation in our country. Systems of use of greywater in selected objects are detaily solved in my dissertation directed at system proposal.

No. of bitstreams: 1 texto completo.pdf: 2077124 bytes, checksum: 59f01201db0c813515df97522a0e48f4 (MD5) Previous issue date: 2008-02-28 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / Paper mill industrial processes consume large quantities of water consequently leading to large mill effluent volumes. One way to reduce water consumption is by increasing water reuse in the paper mill. Direct water reuse is not always possible because of poor effluent quality and effluent treatment may be necessary to permit reuse. Membrane bioreactors are a new treatment technology that are little used, mainly due to the lack of scientific and technical knowledge of their implementation. The present study examined the technical viability of thermophilic treatment of paper machine effluents in a membrane bioreactor. The studied was divided into three experiments. The main objective of the first experiment was to compare performance of laboratory-scale conventional activated sludge (CAS) and a membrane bioreactor (MBR) with 0,02µm porosity membranes in treating printing and writing paper machine white water at 35, 45 and 55°C. Results showed that the BRM was more efficient that the CAS in removing part of the effluent contaminant load. Average percent removals of chemistry oxygen demand (COD) in the CAS were 70.0, 78.1 and 76.7% and in the MBR 81.4, 81.9 and 78.7% at temperatures of 35, 45 and 55°C, respectively. Treated effluent total suspend solids (TSS) values in the CAS were 39, 54 and 88 mg.L-1 at of 35, 45 and 55°C. No TSS were detected in the MBR treated effluent. Turbidities of effluents treated in the CAS were 16, 35 and 165 NTU at temperatures 35, 45 and 55°C. MBR treated effluent presented no turbidity. Alkalinity and hardness of effluent treated by CAS were lower than for effluent treated by the MBR. The main objective of Experiment II was to compare performance of MBR effluent treatment under mesophilic (35°C), thermotolerant (45°C) and thermophilic (55°C) conditions. In Experiment II an MBR system composed of three reactors operating in parallel at the three different temperatures were used. This experiment was divided into three stages, with different COD loads in each: Stage 1 2.57 Kg.m-3.d-1; Stage II 4.75 Kg.m-3.d-1 and Stage III 9.43 Kg.m-3.d-1. The results showed that the increase in temperature led to reduction in COD removal efficiencies. Removals of COD in Stage I were 95.5, 94.2 and 91.9%, at temperatures of 35, 45 e 55°C, respectively. In Stage II, removal efficiencies were 97.4, 95.6 and 95.0% at 35, 45 and 55°C, respectively. In Stage II, removal efficiencies were 95.6, 93.3 and 89.7% at 35, 45 and 55°C, respectively. No TSS were detected in any of the treated effluents. Treated effluent turbidity increased with increased treatment temperature. Average turbidity of treated effluents were 0.11, 0.24 and 1.13 NTU in Stage I, 0.10, 0.16 and 1.01 NTU in Stage II and 0.87, 2.00 and 4.34 NTU in Stage III for treatment at 35, 45 e 55°C, respectively. Average conductivities of treated effluents were 1812, 1937 and 2927 µS.cm-1 for Stages I, II and III, respectively. Treated effluent color was greater for treatment at 55°C. Average color was 23, 23 and 102 mg.L-1 Pt in Stage I, 31, 36 and 127 mg.L-1 Pt in Stage II and 46, 58 and 163 mg. L-1 Pt in Stage III for temperatures of 35, 45 and 55°C, respectively. Average hardness values in treated effluents were 258, 203 and 160 mg.L-1 in Stage I, 439, 350 and 292 mg.L-1 in Stage II and 639, 565 and 495 mg.L-1 in Stage III, for treatments at 35, 45 and 55°C. No filamentous bacteria were found at 55°C and flocculation was deficient. The main objective of Experiment III was to evaluate sludge microbial diversity in aerobic MBRs operating under mesophilic and thermophilic conditions. It was found that increased temperature reduced reactor sludge microbial diversity and richness. A new microbial community was established above 45°C that differed structurally from the community present in the MBR operated at 35°C. / Fábricas de papel consomem elevadas quantidades de água nos seus processos industriais gerando, conseqüentemente, grande volume de efluentes. Aumentar o reuso de água é uma forma que as empresas encontram para reduzir o consumo de água nas fábricas de papel. A reutilização da água nem sempre é possível devido a sua qualidade, o que requer um tratamento prévio. Biorreatores a membranas constituem uma nova tecnologia de tratamento, ainda pouco utilizada em decorrência do desconhecimento técnico e científico para sua implementação. O presente estudo verificou a viabilidade técnica de utilização de biorreatores a membranas para o tratamento termofílico de efluentes de máquinas de papel. O estudo foi dividido em três experimentos. O objetivo principal do primeiro experimento foi comparar o desempenho de um sistema de tratamento de efluentes por Lodos Ativados Convencional (LAC) e um sistema de tratamento de efluentes por Biorreator a Membranas (BRM), cuja porosidade das membranas era de 0,02µm, para remover os contaminantes orgânicos e inorgânicos presentes na água branca de uma máquina de papel para imprimir e escrever em três diferentes temperaturas: 35, 45 e 55 °C. Neste experimento foram utilizados dois sistemas laboratoriais de tratamento de efluentes composto de um LAC e um BRM. No experimento I, os estudos mostraram que o BRM foi mais eficiente do que o LAC para remover parte dos contaminantes presentes no efluente. As percentagens médias de remoção de DQO para o LAC foram 70, 78,1 e 76,7% e para o BRM foram 81,4, 81,9 e 78,7%, para as temperaturas de 35, 45 e 55°C, respectivamente. As concentrações de SST no efluente tratado no sistema LAC foram 39, 54 e 88 mg.L-1 para as temperaturas de 35, 45 e 55°C. No BRM não foi detectado SST no efluente tratado. A turbidez do efluente tratado pelo LAC foi 16, 35 e 165 UNT para as temperaturas de 35, 45 e 55°C. No BRM não houve turbidez no efluente tratado. As concentrações de alcalinidade e de dureza no efluente tratado para o LAC foram inferiores às taxas obtidas pelo BRM. O objetivo principal do Experimento II foi comparar os desempenhos dos sistemas de tratamentos de efluentes por BRM em condições mesofílica (35°C), termotolerante (45°C) e termofílica (55°C). No Experimento II foi utilizado um sistema de BRM composto de três reatores, operando em paralelo, em três temperaturas diferentes. Este Experimento foi dividido em três etapas, sendo que, cada etapa foi utilizada uma carga diferente de DQO: Etapa I 2,57 Kg.m-3.d-1; Etapa II 4,75 Kg.m-3.d-1 e Etapa III 9,43 Kg.m-3.d-1. Os resultados demonstraram que o aumento da temperatura ocasionou uma redução nas eficiências de remoção de DQO. As taxas de remoções de DQO na Etapa I, para as temperaturas de 35, 45 e 55°C, foram 95,5, 94,2 e 91,9%, respectivamente. Para a Etapa II, as taxas foram 97,4, 95,6 e 95,0% para as temperaturas de 35, 45 e 55°C, respectivamente. Para a Etapa III, as taxas de remoções de DQO foram 95,6, 93,3 e 89,7% para as temperaturas de 35, 45 e 55°C, respectivamente. Em nenhum tratamento foi detectada concentrações de SST no efluente tratado. A turbidez nos efluentes tratados aumentou à medida que aumentou a temperatura dos tratamentos. As médias de turbidez dos efluentes tratados, para a Etapa I, foram 0,11, 0,24 e 1,13 UNT; na Etapa II foram 0,10, 0,16 e 1,01 UNT e na Etapa III foram 0,87, 2,00 e 4,34 UNT para as temperatura de 35, 45 e 55°C, respectivamente. A média das condutividades dos efluentes tratados foram 1812, 1937 e 2927µS.cm-1 para as Etapas I, II e III, respectivamente. A cor nos efluentes tratados foi maior para os tratamentos realizados à temperatura de 55°C. As médias das concentrações de cor, para a Etapa I, foram 23, 23 e 102 mg.L-1 Pt; na Etapa II foram 31, 36 e 127 e na Etapa III foram 46, 58 e 163 mg. L-1 Pt, para as temperaturas de 35, 45 e 55°C, respectivamente. Quanto à concentração de dureza nos efluentes tratados, na Etapa I as médias foram 258, 203 e 160 mg.L-1. Na Etapa II, as médias foram 439, 350 e 292 mg.L-1 e na Etapa III, as médias foram 639, 565 e 495 mg.L-1, para as temperaturas de 35, 45 e 55°C. Não foram encontradas bactérias filamentosas na temperatura de 55°C e a floculação foi deficiente. O Experimento III teve como principal objetivo avaliar a diversidade biológica dos microrganismos em dois BRMs aeróbios, nas condições mesofílica e termofílica. Este experimento verificou que o aumento da temperatura reduziu a diversidade e a riqueza dos microrganismos presentes no lodo. A partir de 45°C estabeleceu-se uma nova comunidade microbiana, diferente das comunidades presentes nos reatores à temperatura de 35°C.
