Item Caracterização de resíduo de ETA visando sua disposição na saída de lagoas de estabilização(2014-03) Soares, Lorena Acelina; Scalize, Paulo Sergio; Albuquerque, Antonio João CarvalhoThe WTP are responsible for the production of drinking water to be consumed by the population, which generates social benefits, however, as in any manufacturing industry, waste is generated and there is the need to dispose them properly without harming the environment. The solid waste management included waste destination and for this stage is necessary to know the waste characteristics in order to define the best treatment and disposal. This study aimed to characterize the WTPS produced by a WTP in the state of Goiás, Brazil, that employs in their treatment the coagulant aluminum sulfate. Physico-chemical analyses and structural properties were verified, showing that the residue consists of clay (mainly the mineral kaolinite and halloysite), silt and sand. The residue was determined as not plastic. The EDS analysis detected the presence of aluminum, which is related to the phosphorus removal in water and sediment, which facilitates their reuse in the wastewater treatmentItem Caracterização física do resíduo de uma estação de tratamento de água para sua utilização em materiais de construção(2015-12) Araújo, Flávio de Carvalho; Scalize, Paulo Sérgio; Albuquerque, Antonio João CarvalhoIn the Water Treatment Plants (WTPs), the production of treated water generates residues, which are usually called water treatment residues (WTR). Most of these WTPs discharge waste into watercourses, despite the national solid waste policy assigning responsibility for adopting sustainable ways to disposal the wastes to the generating source, because its launch “in natura” in water bodies is harmful. The aim of this work was to determine the physical characteristics of the waste generated in a Water Treatment Plant according to normative parameters in order to consider sustainable alternatives for its reuse in the production of building materials and, therefore, reducing the potential environmental impacts on water streams. Thus, the following tests were performed on the residue: consistency index, granulometry, scanning electron microscopy and energy dispersive spectroscopy. The results show the potential application of the residue for partially replacing soil and/or sand in the production of construction and building materials.Item Estudo da influência da temperatura da água bruta na eficiência do coagulante químico(2012-08) Scalize, Paulo Sérgio; Figueiredo Neto, Abner; Rios, Fernanda Posch; Albuquerque, Antonio João CarvalhoThe study was conducted using bench tests using Jart in order to evaluate the efficacy of three coagulants used in water treatment plants. Samples of raw water from the spring that supplies the Water Treatment Station Jaime Camara, located in Goiânia, Goiás, Brazil. The tests were performed at different temperatures, and applied different doses of aluminum sulfate, ferric chloride and ferric sulphate. Was studied by pH, the removal of turbidity and apparent color. The parameters have been interfered with in relation to dosage, type of coagulant and temperature, which demonstrates the need for monitoring the water temperature for adequacy of dosage of these chemicals in a Water Treatment Plant.Item Filtração em cerâmica microporosa apicada à remoção de cor e turbidez de água para abastecimento público(2013-02) Scalize, Paulo Sérgio; Teixeira, André Luiz; Teran, Francisco Javier Cuba; Albuquerque, Antonio João CarvalhoA 60 cm-high, 6 cm-diameter, 1 cm-thick ceramic filter with porosity of 0,1μm was the object of this research which aimed to study the removal of color and turbidity from raw water. The device had 0,113 m2 of external surface and was installed inside an acrylic column 110 cm high and with inner diameter of 23 cm. This column had a volume of 41,5 L. Raw water was collected from a … where turbidity varied from 2,3 to 2,8 NTU and apparent color from 1,82 to 3,26 PtCo. Three different application rates were applied (1,82, 3,16 e 4,49m3/m2.dia) accomplishing three filtration runs for each one of them. Water samples were collected from influent and effluent of filter each time that head loss raised in 5 cm, until 20 cm of head loss were completed. Results showed 75 to 80 % efficiency in turbidity removal, resulting in values between 0,53 to 0,58 NTU for the last run for each filtration rate applied. In the other hand, system doesn’t show efficiency for the removal of color.Item Remoção de metais pesados por fi ltração reativa com resíduo de ETA(2014-02) Albuquerque, Antonio João Carvalho; Scalize, Paulo Sérgio; Silva, Isabel; Soares, Lorena Acelina
