The logistical challenge of transporting fruit over long distances and during the off-season has driven the development of processing techniques, resulting in a variety of products such as juices, pulps, and jams. The industrialization of fruit pulp has expanded the reach of the products, making them accessible throughout the country, with a diversity of fruits from different regions. In this context, the work proposed the implementation of standard operating procedures (SOPs) in a fruit pulp agroindustry, focusing on the identification of the importance of SOPs, understanding the main stages of fruit pulp manufacturing and development of SOPs to sanitize the facilities and ensure the health of the handlers. To achieve these objectives, the methodology involved an exploratory review of the literature, collection of bibliographic data, descriptive and explanatory analysis of the SOPs, as well as qualitative analysis of the practical challenges of implementation. The qualitative analysis identified the challenges found in the literature in relation to SOPs, while the quantitative analysis identified the efficiency of SOPs after their practical implementation. The results of the implementation of SOPs highlighted their importance in ensuring food quality and safety, as well as their contribution to optimizing production and reducing errors. I concluded that the implementation of SOPs and Good Manufacturing Practices (GMP) is essential to ensure the quality of products in a fruit pulp agroindustry, promoting food safety and production efficiency 2024-01-01T00:00:00Z https://repositorio.unifaema.edu.br/jspui/handle/123456789/3592 Title: CARACTERIZAÇÃO E PROPOSTA DE TRATAMENTO DE LODOS PROVENIENTES DE ESTAÇÃO DE TRATAMENTO DE ÁGUA DE UM MUNICÍPIO DE RONDÔNIA Abstract: Water Treatment Plants (WTPs) are essential for providing high-quality water to the population. However, many Brazilian states face challenges in managing sludge, an unavoidable solid waste generated during these operations. Proper management of this waste is mandated by legislation aimed at preventing environmental impacts. Nonetheless, sludge management involves reducing the water content and increasing the concentration of suspended solids through the combination of thickening and dewatering techniques, whether mechanized or natural. In this context, the present study aims to characterize and quantify the sludge production in a WTP located in a municipality in Rondônia, as well as to propose the most viable solutions for its treatment and final disposal. The methodology consists of descriptive and exploratory research, including data collection from the WTP and a literature review to suggest operational improvements for sludge management. Based on the results obtained from physicochemical analyses, it was observed that the sludge from the clarifier has significantly higher concentrations of suspended solids and turbidity compared to the sludge from the filters. Furthermore, it was possible to estimate the daily production of dry sludge, which amounts to 1,176.12 kg/day. The proposed treatment technique for the clarifier sludge was gravitational thickening followed by centrifuge dewatering, with final disposal in a sanitary landfill. Meanwhile, the filter sludge was directed to equalization tanks for reuse in the initial treatment stage. Thus, this study provides valuable insights to assist in the management of sludge generated in WTPs and supports decision-making in municipalities facing similar challenges regarding sludge disposal 2024-01-01T00:00:00Z https://repositorio.unifaema.edu.br/jspui/handle/123456789/3591 Title: DIMENSIONAMENTO DE UM SISTEMA WETLANDS CONSTRUÍDO PARA TRATAMENTO DE ÁGUAS RESIDUAIS DE UMA AGROINDÚSTRIA DE POLPA DE FRUTAS NO MUNICÍPIO DE ARIQUEMES – RO Abstract: Esta pesquisa teve como objetivo dimensionar um sistema de Wetlands Construídos de fluxo subsuperficial horizontal para tratar efluentes gerados em uma agroindústria de polpa de frutas congeladas, localizada em área rural. A coleta de dados incluiu visitas à agroindústria, entrevistas com os proprietários e análise documental dos processos de produção e consumo de água. A metodologia foi fundamentada na revisão de literatura sobre tratamentos de efluentes utilizando wetlands, com destaque para os estudos de Marcos Von Sperling e Pablo H. Sezerino. O dimensionamento do sistema foi realizado com base na cinética de primeira ordem, amplamente utilizada no tratamento de efluentes com baixa carga orgânica, visando garantir a eficiência do tratamento e a viabilidade prática para a agroindústria em estudo. Os resultados indicaram que, para o volume e características dos efluentes, o sistema projetado apresentou um tempo de detenção hidráulica adequado e um meio de suporte com porosidade de 35%, demonstrando a viabilidade técnica e ambiental da solução proposta. 2024-01-01T00:00:00Z https://repositorio.unifaema.edu.br/jspui/handle/123456789/3590 Title: DELIMITAÇÃO DE ÁREA DE PRESERVAÇÃO PERMANENTE EM TOPO DE MORRO NA BACIA HIDROGRÁFICA DO RIO JAMARI Abstract: Permanent Preservation Areas (APPs) on hilltops regulate runoff and reduce erosion, which are essential for the environmental sustainability of river basins. However, the presence of human activities in some APP areas points to challenges in the full protection of these spaces. Brazilian environmental legislation seeks to balance environmental protection requirements with the country's socioeconomic development, particularly pressures from the agricultural sector, which have raised questions about the effectiveness of legal enforcement in sensitive areas, such as river basins. In this regard, we sought to analyze the compliance between hilltop APPs and the forest vegetation still present in these areas, in accordance with the Brazilian Forest Code, in the Jamari River Basin (BHRJ). The methodology involved the acquisition of satellite images and the processing of Digital Elevation Models (DEM) to generate slope and hypsometry maps and to delimit the hilltop APPs using the free software QGIS, combined with the GRASS, SAGA and GDAL resources. The analysis of the hilltops revealed altitudes ranging from 100 to 566 meters and slopes reaching up to 89. The total area delimited as hilltop APP was 693.0 km², of which 433.42 km² (62.54%) still have forest vegetation, 29.11% are composed of pastures, while the remainder (8.34%) is represented by the classes of non-forest natural formation, non-vegetated areas, water bodies and agriculture. The distribution of APPs showed that the largest concentration is located in the southern portion of the basin. 2024-01-01T00:00:00Z
