Industrial activities generate too much effluents which, if not treated properly, generate pollution and damage to water resources, which makes environmental requirements severest. The project proposes to a dairy industry, specialized in the production of cheese bread, an efficient treatment of effluents, technically and economically viable of its waste generated in the process that is currently launched without treatment in nature, with a high pollutant load characteristic of waste from the dairy industry. For this, bibliographical surveys were carried out on the subject of effluent treatment, application of a questionnaire in the company and the physico-chemical characterization of the generated effluent with the purpose of elaborating the design of the Vermifiltro. Thus, the result of this work is the complete design of the treatment system that was proposed to the industry, composed of the results of laboratory analysis, sizing calculations, low plan of the implantation site, as well as the schematic design of the Vermifiltro. Therefore, Vermifiltro appears as an option to remedy environmental pollution, as well as showing itself as an efficient and economically viable technique in relation to conventional treatments, since the release of tailings in water resources directly affects its quality, changing its characteristics originates and causes in several imbalances, which evidences the necessity of the implantation of a treatment system.

Droughts affect semiarid regions worldwide, threatening economic activities and lives of people living in these places. In Brazil, 11% of the population inhabits the semiarid, and despite several mitigation measures taken by the State, it is still ranked as the most vulnerable Brazilian region and potentially the most affected by climate change. Throughout Brazilian history several public policies focused on water supply in the semiarid region have failed for different reasons. Two recurring arguments are the lack of financial resources and poor management. This work presents an analysis of a public policy that aims to provide quality and perennial water by desalting local brackish groundwater, the Programa Água Doce (PAD). We used the ecodevelopment theory to discuss the economic sustainability of the policy. The methodology used was a documental analysis, and a literature review to understand PAD’s main strengths and weaknesses. We found that the continuous flow of public and private investment was a decisive element to the implementation of the technology during the initial transference of responsibilities moment. In addition, by the gradual reduction of public investment, the management of the systems became local and funded by private resources from the beneficiaries. The PAD presents, in its dynamics, advances in the field of the dissemination of water treatment technologies and social technologies, especially in relation to the Management Agreements. However, the lack of processes for community empowerment and no strengthening of cooperativism resulted in disconnected systems that were not able to ensure economic sustainability.

The preservation of the environment is one of the most relevant issues today. In view of new concerns and positive perspectives regarding the adoption of sustainable development policies, it is necessary that environmental education be treated in the daily life of individuals from a young age, thus contributing to the construction of habits and attitudes of preservation of quality of the environment to which they are inserted. This article aims to highlight how the environmental education implanted in the Crê-Ser Foundation in João Monlevade-MG, contributed to raising awareness and awareness among students. For the development of the research, we used data obtained through bibliographical research and methodologically planned meetings at the foundation, where we sought to transmit information in a playful way, from the wheels of conversations and interactive activities. With the data obtained in the foundation it was possible to perceive a cleaner and more organized environment, besides changes of behavior, that contribute to a better quality of life. Environmental Education is effective in training individuals, making them reflect and acquire knowledge about environmental practices and ways of minimizing environmental damage.

This study aimed to find a dose of powder prepared from the Moringa Oleífera seed, which is efficient in removing turbidity from water used for human consumption in the rural community of Capela Branca, located in the city of Bela Vista de Minas. A solution was prepared with the plant seed. The experiment was carried out in a Jar Test, where the respective quantities of the prepared solution were first added to each jar of the solution: 5 mL, 10 mL, 15 mL, 20 mL, 25 mL and 30 mL. The solution initially added to the jars was added to the respective amounts: 20 mL, 40 mL, 60 mL, 80 mL, 100 mL and 120 mL. Afterwards the solution was again raised to: 30 mL, 60 mL, 90 mL, 120 mL, 150 mL and 180 mL. Since in the first three experiments there was no efficiency in turbidity removal, the jars were emptied and only 4 of them were filled again for the new test. In each of the 4 jars were added respectively: 0.2160g, 0.432g, 0.648g and 0.884g of the Moringa Oleifera seed powder together with 10 ml of the initially prepared solution. It was possible to notice that the third jar, where 0.648 g of Moringa Oleífera seed powder was added, demonstrated the efficiency of the turbidity removal of 2L of water. It is concluded that the amount of the powder that guarantees turbidity removal efficiency (0.648g) is equivalent to approximately 3 crushed seeds, and higher or lower doses do not work efficiently to remove turbidity.

This paper aims to analyze the sanitation services of the rural community of Amadeu Lacerda in the municipality of Divinópolis, Minas Gerais, Brazil, from the perspective of the thematic categories of rural management and economic sustainability, addressing their aspects and particularities in discussion with the state of the art. The work presents itself as a qualitative and quantitative, exploratory and analytical research. Using the technique of field diary research and direct observation, a mapping and diagnosis of the existing systems and structures was performed. The analysis of the financial sustainability of the water supply system points to the inability to fund the necessary actions and to provide the service satisfactorily, interfering with issues such as installation and maintenance of treatment structures, water quality control and fund administration. reserve for possible expenditure. The management of the sanitation service of the community of Amadeu Lacerda is precarious in different aspects, from the point of view of operation, maintenance, logistics, as well as in human resources and system permanence, directly impacting the quality of life of the population. It is proposed as an alternative the adoption of the management model based on self-organization, which can contribute both to the improvement of the service as well as to the engagement and empowerment of community residents.
