Así mismo con la cáscara de cacao se ha obtenido compost en pilas abiertas por proceso aeróbico, para la obtención de un bioabono de alta calidad respecto a N, P, K y micronutrientes como Mg, Mn, Zn y Ca. Las concentraciones de los productos obtenidos fueron: ART de 7,3 g/L; porcentaje de bioetanol de 4,7 % del agua miel sin pasteurizar y 4,1 % de agua miel pasteurizada, utilizando como cepa al Sacharomyces cerevisceae comercial; respecto a la concentración de N-P-K en el compost de gallinaza se obtuvo 0,56; 0,03; 0,20 %; compost de cuy 0,29; 0,02; 0,16 % y compost de vacuno 0,29; 0,02; 0,23 % de N-P-K respectivamente, siendo esta composición la indicada para aplicarlas en suelos ácidos debido a que tiene un pH promed...

La zona del Alto Mayo cuenta con una gran variabilidad en flora y fauna, una abundante vegetación y muchas vertientes acuáticas, ya sean galerías filtrantes o manantiales de agua dulce, que son aprovechadas por los pobladores de la región con la finalidad de satisfacer la necesidad básica del agua y alimento; el problema está que estas aguas que afloran a la superficie sin tratamiento alguno tienen en su composición hierro y manganeso. Así mismo la zona de Yantaló tiene acuíferos que son aprovechados por los pobladores, y por ser zona cafetalera, generan como residuos cáscara de café, las que pueden ser aprovechadas, como filtro que retenga estos metales pesados, no sin antes pasar por un proceso cuidadoso que es la transformación a carbón activado, siendo la presente investigación: Efecto del carbón activado, obtenido experimentalmente a partir de cáscara de café (Coff...

The first phase consisted of removing and reducing non-reducing sugars and tannins. By anaerobic fermentation processes in a bioreactor BATCH type agitator, far preparing alcohols. The second phase addressed the honey water treatment; bioremediation using a model of effective microorganisms (EM) and aquatic macrophytes was used. Under the study conditions 18.8 g of reducing sugars per liter Totals were obtained from the dried pulp and 2.0% bioethanol per liter of wine. Gallic acid was obtained as primary and most abundant polyphenols in a concentration of 4555.2 mg / kg of dry pulp. Regarding treatment of honey water results BOD and COD decreased, not reaching below the LMP, the STS is able to reduce below the LMP, the pH is within the range of the LMP, the temperature is below the LMP, like nitrates. Thus, it was concluded that it is possible, first use and transform agricultura! waste ...

La coagulación y floculación constituyen la base en los tratamientos de agua, para la separación de mezclas sólido-líquido, así como un medio de disminución de la turbidez. En la presente investigación, se evalúo el efecto que ejerce la velocidad y dosis aplicada de sulfato de aluminio Al2 (SO4)3, así como la ejercida por el cloruro férrico FeCl3-floculante. Para la obtención de los datos experimentales, se utilizó un equipo de “Test de Jarras”, realizando pruebas a 06 niveles de dosis aplicada (1, 2, 3, 4, 5 y 6 mL), y a 05 niveles de velocidad de agitación (100, 150, 200, 250 y 300 r.p.m.). Los resultados reportan que las mejores condiciones, con Sulfato de Aluminio, se lograron con una dosis de 120 mg/L y a una velocidad de 100 r.p.m. de mezcla rápida y 25 r.p.m. de mezcla lenta, disminuyendo el color inicial de 213 UPC hasta 10 UPC, una turbidez inicial de 66.6 has...

La importancia del tratamiento de las aguas provenientes de quebradas es importante, debido al hecho de mejorar su calidad y contribuir a mejorar la salud de las personas, mediante la propuesta de utilización de coagulantes de origen natural (polímeros naturales), hechos a base de sustancias orgánicas (almidón de yuca y de plátano). En la presente investigación, se determinó el efecto del proceso de coagulación floculación, con polielectrolitos naturales, en la remoción de la turbidez y el color, del agua proveniente de la quebrada Pucacaca. Los métodos utilizados fueron el tratamiento con prueba de jarras, utilizando almidón de yuca y plátano. Se demostró que los resultados para la remoción del color, en los diferentes tratamientos fueron eficaces en mayor valor en los ensayos con el almidón de yuca al 1% y 2%, llegando a valores de 5,17 UPC, conforme con lo que dice el ...

Projections of water availability in the near future are increasingly worrisome due to climate change. It is, therefore, high time to seek and develop technologies that would guarantee water availability in the future. In this respect, desalination of seawater is one of the most important alternatives, as specific attention needs to be directed at improving the existing techniques of it. This is why updating information about new achievements for researchers is so important in improving such technologies. This comprehensive review article analyzes advancements in seawater desalination through a bibliometric study encompassing 8523 scientific papers published from 1966 to 2023. The analysis identifies eight key research areas, highlighting significant improvements in energy efficiency and membrane technology. The review examines innovative approaches, including the application of nanopart...

The Moche River water is contaminated due to informal mining and other anthropogenic activities. The pollutants are primarily organic matter and heavy metals, which contribute to the water’s elevated color and turbidity levels. This contaminated water is used for irrigating surrounding areas, leading to the production of contaminated crops. Monitoring color and turbidity requires expensive instruments. In this study, a water sample was collected from the district of Poroto, located in the province of Trujillo, La Libertad region. Approximately 200 L were sampled, with a pH of 5.2 and a turbidity of 12.04 NTU. The research employs a combined treatment process involving coagulants, specifically ferric sulfate and polyaluminum chloride, followed by filtration through activated carbon. Additionally, a low-cost monitoring system using an Arduino-based turbidimeter and colorimeter is propose...

In the present study, the influence of temperature and activating agents in the production of activated carbon from peach pits was evaluated to determine the most effective removal of water hardness. To obtain experimental data, activation was carried out using a 1:1 ratio of KOH, H3PO4, ZnCl2, and H2SO4 at temperatures of 400°C, 500°C, and 600°C. The results indicate that the highest preparation yield was achieved with carbon activated by H3PO4 at 400°C, resulting in a 47% yield. In all activation cases, the surface acidity, determined by Boehm titration, exceeded the basic character. The predominant acidic character was obtained with ZnCl2 at 500°C, reaching 62.08 mol%; acid character analyses were supported by zero-charge point pH analysis. The best iodine index analysis results were 797.22 mg/g and 747.72 mg/g, obtained with ZnCl2 at 400°C and 600°C, respectively. The activate...

Climate change represents one of the greatest challenges we face globally, and reducing carbon dioxide (CO2) emissions is among the most urgent actions. In this study, we explored an alternative approach using microalgae (Chlorella vulgaris) to capture CO2 from the air, employing an Arduino-controlled biofiltration system with accessible sensors such as the MQ-135 and TESTO 535. We tested different airflow rates (50, 75, and 100 L per hour) and nutrient combinations (N/P ratios of 0, 108.33, and 216.67) to identify the most efficient conditions. Unlike other studies, we integrated real-time monitoring of variables such as CO2 concentration, temperature, and light within a modular, easily adaptable system. The best results were achieved with a flow rate of 100 L/h and an N/P ratio of 216.67, yielding a capture efficiency of 34.88 % and a daily productivity of nearly to 1 g/L. This proposa...
