En la investigación se utilizaron las redes neuronales artificiales como herramienta para optimizar la cantidad de coagulante (Al2SO4) que se utiliza en el tratamiento del agua potable de la empresa SEDAM de la ciudad de Huancayo – Perú, donde la calidad del agua al ingreso a la planta de tratamiento tuvo variabilidad permanente de turbidez debido a las precipitaciones fluviales que se presentaron generalmente en los meses de octubre a marzo. Este fenómeno meteorológico alteró en corto tiempo las características físicas y químicas del agua dificultando su tratamiento. Se utilizó en el laboratorio el ensayo denominado Prueba de Jarras para determinar la dosis de coagulante a emplear durante un periodo de once meses, con muestreo aleatorio diario. Las variables consideradas para el estudio fueron la turbidez, el pH, la conductividad, el color y sólidos disueltos totales con una...

Huancayo is a city located at Peruvian Central Andes and presents air pollution problems related to particulate matter (PM), especially fine fraction (PM2.5). Given the high costs of air quality monitoring network infrastructure and the need for more detailed information, the objective of the study is to evaluate the temporal variation and source zones of PM2.5 through the use of low-cost sensors installed at three sites in the city of Huancayo. PurpleAir PA-II model PMS5003 sensors were employed from August 2018 to June 2019. The dataset was subjected to statistical tests to evaluate temporal changes. Backtrajectories were calculated through the HYSPLIT model for source zone identification. The results show reasonable agreement with other reference monitoring. The importance of the use of low-cost sensors in the establishment of an air quality monitoring network in high Andean areas is ...

The study is carried out in a domestic wastewater treatment plant (DWWTP) in the city of Morococha in Peru, with a population of 9 thousand inhabitants, at an altitude of 4200 m.a.s.l., has a processing capacity of 1620 m3 /day with a flow that is not constant, focuses on secondary treatment consisting of a sequential biological reactor (SBR) of aerobic technology. The problem is the excess flow in certain periods of time and the incoming wastewater was not processed in an optimal way, as an objective a redesign of the bioreactor was proposed, incorporating a Rushton Turbine of 6 horsepower (H.P.) of power with 6 propellers and dimensioned according to mathematical models, the results were the improvement of effluent quality for turbidity, dissolved oxygen, pH and re- sidual chlorine, improving the reaction speed, and controlling the treatment flow, providing a better quality effluent to...

This work evaluates the technical feasibility of installing photovoltaic solar panels for homes in the city of Huancayo, Peru. For this, variables such as: solar radiation, orientation, angle of inclination and electrical power were taken into account. The development of the study was carried out in the renewable energy laboratory of the electrical and electronic engineering faculty of the National University of Central Peru, which is located in the city of Huancayo. The prototype used was model YI6R-30P, polycrystalline silicon at 30 watts and 12 VDC. With the objective of optimizing the variables of the study for the efficient use of the solar panels that are being used in the present work. The data collection was evaluated in 3 consecutive months of this year, where the electrical power generated according to the solar radiation obtained during each month, with an orientation (0°N an...
