The quality of water for human consumption in the municipality of Los Patios in Colombia, depends 60% of the treatment systems for drinking water (STAP) independent, these are adapted according to the population that conforms in 2014 and own resources. Urbanization San Fernando carries out the treatment in an efficient way guaranteeing the quality of water for human consumption, therefore, the field study is based on a quantitative approach and a method that describes the results of the analysis of the samples taken at the entrance and exit of the STAP, to evaluate the efficiency and quality of the system the sample is characterized from the analysis of the physical-chemical and microbiological parameters at the entrance and exit of the system in the Water Laboratory of the Universidad Francisco de Paula de Santander. The physical and microbiological results identify the efficiency of the system and the operator, indicating the quality of the water by the values in the parameters measured according to Decree 1575 of 2007 and 1525 of 2007 by the Ministry of Social Protection in Colombia. The chemical analyses detected a high percentage of calcium hardness in the sample at the system outlet, which is reportedto the directors of the urbanization. In accordance with this, the relevant controls and monitoring are carried out in the process for the purification and consumption of water, without neglecting the habits of water storage by the community in each home.

This study analyzes the operation of Biomass System (BIO System) technology for the combustion of pellets from almond and olive trees within the circular economy model. Its aims are the reduction of greenhouse gas emissions as well as waste removal and its energy use by reintroducing that waste into the production process as technological nutrient. In order to do so, combustion efficiency under optimal conditions at nominal power was analyzed. In addition, a TESTO 350-XL analyzer was employed to measure CO and NOx emissions. High combustion efficiency values were obtained, 87.7% and 86.3%, for pellets from olive tree and almond tree, respectively. The results of CO and NOx emission levels were very satisfactory. Under conditions close to nominal power, CO emission levels were 225.3 ppm at 6% O2 for pellet from almond tree and 351.6 ppm at 6% O2 for pellet from olive tree. Regarding NOx emissions, the values were 365.8 ppm at 6% O2 and 333.2 ppm at 6% O2 for pellets from almond tree and olive tree, respectively. In general, these values were below those legally established by current legislation in European countries. Therefore, BIO System technology is a perfectly feasible option in terms of energy use and circular economy.

This paper presentsan energetic and exergetic analysis for ageneration of turbine work according to the variation of the pressure in the condenser regenerative Rankine cycle, implementing an educational graphical user interface known as Power Cycle version 2.0; that is used as a pedagogical strategy in thefield ofengineering education. The mains objectives were, analyzethe efficiency of first and second thermodynamic law, and the generation of turbine work according to the variation of thecondenser pressure, at three different temperatures in the boiler, as well as analyzing the components of the system to identify and quantify where the exergy destruction was maximum. According to the results in the cases studied, the percentage ratio of the exergydestruction to the total exergy destruction was found to be maximum in the boiler 62.18%, then the turbine 22.79%, and finally 15.03% in the pumps, the heater and the condenser. On the other hand, the maximum calculated thermal efficiency was 38.34%, while the maximum exergetic efficiency was 62.81%. A significant increase in efficiency of the cycle is obtained by decreasing the pressure in the condenser.
