Abstract: The Córrego do Sapo is a relevant watershed in the municipality of Rio Verde (GO), its main water body is partially channeled in the urban section, so that 80% of the urban area drains into the stream, being affected by low-income housing invasion, domestic or industrial clandestine sewage, surface runoff and drag of solids to the stream bed. This sediments reservoir for the stream channel can cause its silting up, increasing the probability of roads flooding, in addition of reducing the water quality. Thus, this study aimed to analyze the relationships between rainfall erosivity, soil erodibility, relief aspects, land use and land cover and the Sapo creek hydrographic basin, for dry and rainy seasons. For this, free databases and the Universal Soil Loss Equation (USLE) were used, with the use of remote sensing and geoprocessing. Potential soil loss was predominant in the weak classification, about 71% of the total studied area, the most influential factor was the LS (ranging from 0 to 81.6), in which great similarity was demonstrated between the maps of the LS factor and the downward influence, which shows how the topographical influence of the atmospheric influence. For real soil loss estimation, the light category prevailed (51%), followed by very high (14%), with values from 0 to 1136.5 tn.mm.ha-1.year-1, with the highest results observed in areas close to water bodies, combined with high topographic values and pasture use. The basin was characterized as urbanized, approximately 58% of the total area (3166.1 ha). The results of this study demonstrated the importance of good management practices, since the basin in question presented areas with high values for management, which, combined with its location and land use and cover, can bring environmental and health damage. The work can be used to implement actions for the management and planning of the basin's natural resources.

Abstract: One of the economic activities that demand a high amount of water resources within
urban areas is the vehicle washing service, also known as “lava-jets”. The effluent
generated is not reused and dumped into the environment without treatment. In this
context, the objective of this study is to carry out the treatment of ARLJ- Lava Jato
Wastewater, with systems that are low cost and easy to operate and maintain. Lava-Jato
Esteticar, located in the municipality of Rio Verde (GO), was chosen for the
implementation of the project, which consists of 2 different types of slow filtration
systems, both followed by an activated carbon filter and a polypropylene filter. The
following parameters were analyzed: pH, apparent color, true color and turbidity,
comparing the results based on national standards. Treatment 1 presented the following
average efficiencies: apparent color 88.53%; true color 80.98% and turbidity 94.28%.
While treatment 2 presented the following average efficiencies: apparent color 93.04%;
true color 90.79% and haze 97.93%. Both systems greatly clarified the raw effluent and
showed good efficiencies, especially system 2 with results within the limits allowed in
the national standard NBR13969 for reuse in vehicles. However, in operational terms,
system 2 has a disadvantage, since it operates with lower flow rates. System 1 presents
results accepted in less strict standards such as SABESP, and the treated water can be
used for washing vehicles, washing floors, watering gardens, flushing toilets, among
others.

Abstract: Pig farming emerges as an important activity related to protein production, as well as the development of municipalities in the interior of the country. Like any agro-industrial activity, the use of water and the disposal of waste are intrinsic to the process, but in this specific case, the waste is highly polluting due to the presence of a high organic load and pathogens. As an aggravating factor, Rio Verde is located on the Guarani Aquifer System – SAG, which requires extra care in terms of its use in the soil as fertilizer. A common way of treating these wastes is through stabilization ponds, but with low efficiency. With the use of anaerobic biodigester, in addition to enhancing substrate degradation, it provides biogas as a source of renewable and decentralized energy. Although they are already widely used technologies, biodigesters have a certain complexity in operation. The objective of this work is to compare the performance of two different technologies of anaerobic digestion in the region of the Southwest of Goiás, being a Continuous Stirred Tank Reactor - CSTR and the other with Biodigestor Lagoon Covered-BLC, through the analysis of the concentrations of macro and micronutrients , pH, organic matter (OM) and dry matter (DM) of the digestate and also monitoring the components of the biogas Methane, Sulfidric Acid, Carbonic Gas and Ammonia, to evaluate the best technology of anaerobic digestion for biogas production in the southwest region of Goiás. Such technologies are employed in two finishing farms with an average occupancy of 12,000 pigs, in the city of Rio Verde - GO. The semi-solid samples were collected through 6 visits between 30 and 40 days apart, in a time interval of eight months, at the entry and exit points of each biodigester and at the exit of the stabilization lagoon, totaling 36 samples. Gas samples were collected at the gas outlet of each biodigester, totaling 48 samples. The nutrient parameters were obtained through soil analysis laboratories in the city of Rio Verde and the biogas concentrations through the Alfakit biogas analysis kit. The results showed that both systems are similar in reducing the organic load. The CSTR operating alone did not result in better levels of CH4 and H2S than the BLC. The BLC, already widespread in the region, can be optimized with equipment adopted in the CSTR, such as pre-agitation and internal agitation of the manure, ensuring the best performance during anaerobiosis. The monitoring of waste variables such as MO, MS, pH, collaborate against wasting water in the facilities. The monitoring of biogas variables, on the other hand, is fundamental for the good and constant functioning of energy generation systems. The injection of O2 to reduce H2S is fundamental for the full use of biogas in energy generation, but the daily injected volumes must be calculated for each case and the resulting must be monitored frequently in the plant.

Abstract: Facing a scenario in which the world population is constantly growing, it is necessary to search new technologies so that it is possible to increase food production in the long term. Therefore, technologies such as vertical farms are becoming increasingly relevant within agriculture. These technologies consist of environments where variables such as ambient temperature, soil moisture, air humidity, natural lighting and artificial lighting are controlled to optimize the production process. Thus, this work consisted of evaluating the impacts of substrate heating on the vegetable seedlings production. A substrate temperature control system was developed using the PID technique so that there were no temperature fluctuations during planting. The same technique was used to control irrigation water temperature to avoid thermal shock, and possible seed impracticability during the irrigation process. A soil moisture control system was used to ensure that the cultivars were always in the ideal condition. In view of this, it was possible to conclude that the substrate heating has positive or negative impacts on seedlings production depending of the temperature range, and the species used.
