El objetivo del presente estudio es evaluar el uso de un biocoagulante a base corteza yuca (Manihot esculenta) para mejorar la calidad las aguas residuales domésticas, comparándolo con cloruro férrico (FeCl₃) como coagulante químico. Se recolectaron muestras agua una laguna oxidación en Calceta, Ecuador, y se analizaron varios parámetros agua. Los resultados mostraron que FeCl₃ efectivo remoción sólidos totales (ST) turbidez, mientras destacó reducción suspendidos (SST). La combinación ambos...
The phenomenon of antimicrobial resistance (AMR) in cold environments, exemplified by the Antarctic, calls into question assumption that pristine ecosystems lack clinically significant genes. This study examines molecular basis AMR Acinetobacter spp. Isolated from Antarctic soil, focusing on blaTEM and blaSHV genes associated with extended-spectrum beta-lactamase (ESBL) production; Soil samples were collected processed to isolate soil bacteria. Molecular detection was then conducted using...
The objective of this study is to present a literature review that analyzes how the low carbon/nitrogen (C/N) ratio in domestic wastewater limits microbial activity processes such as anaerobic digestion, affecting degradation contaminants. incorporation bioplastics derived from banana peel (Musa paradisiaca) proposed contribution biodegradable organic carbon optimize C/N and improve denitrification. Bioplastics, rich starch nutrients, increase treatment efficiency, valorizing agricultural...
Se evaluó el agua efluente de lagunas oxidación en Calceta, Ecuador, y su tratamiento posterior mediante avanzada.

La gestión inadecuada de lodos residuales en lagunas oxidación genera acumulación materia orgánica y contaminantes, planteando un reto ambiental. Las celdas microbianas combustible (CMCs) ofrecen una solución innovadora para producir bioenergía tratar aguas residuales. presente revisión sistemática tiene como objetivo evaluar el efecto la producción a partir lodo residual mediante combustibles, través análisis descriptivo literatura científica existente. Los resultados indican que las CMCs...
Plastics pollution is a major worldwide concern because there strong evidence about marine influence on the human trophic chain.Thus, we experimented with biodegradation of low density polyethylene (LDPE) by A. niger and terreus in order to increase degradation rate without any co-substrate or photothermal treatment.Our contribution show how degrade LDPE under minimum nutritional conditions using both sucrose as carbon sources.Up 30% weight loss was obtained which were isolated from an...
C. canephora (syn. robusta) is distinctive due to its rising industrial value and pathogen resistance. Both altitude post-harvest methods influence coffee cup quality; however, modest information known about this species. Therefore, the aim of study was determine relationship between four different altitudes processes (dry, honey, wet) improvement organoleptic quality congolensis conilon drink. For dry processing, showed lowest scores in terms fragrance/aroma, flavour, aftertaste, salt–acid,...
Abstract Leachate, a wastewater produced when rainwater percolates through landfill materials, is global concern for environmental contamination. The goal of the current research was to treat young leachate using aerobic-anaerobic, coagulation-flocculation, and advanced oxidation technologies considering significance pollution caused by on scale. High turbidity, dark brown colour, dissolved organic compounds were removed from that collected in Chimbo, Ecuador. Biochemical oxygen demand (BOD)...
Heavy metals are one of the leading environmental pollutants that hazardous to health humans, soils, plants, and aquatic life.This study investigated potential Athyrium filix-femina, Ludwigia peruviana, Sphagneticola trilobata for phytoextraction Al, Ag, Cd, Cr, Ga, Sr.To evaluate heavy metal uptake by a pot experiment was conducted using uncontaminated soil mixed with solution.At end thirty days planting, bioconcentration translocation factors were calculated.Cd accumulated greater degree...
This review examines the economic impact of Latin American regulations, strategies, and community involvement in mitigating detrimental effects mismanaged municipal domestic wastewater on public health, safety, economy.A systematic meta-analysis are conducted to assess potential reclaimed water region, utilizing various data sources methodologies.The findings reveal that America faces challenges treatment, regulation, resource management, affecting market water.However, recovery initiatives...
La contaminación industrial y agrícola ha generado indudablemente un alto impacto ambiental en los recursos naturales de nuestro planeta. Se prevé carencias la provisión agua para consumo humano debido a fuentes naturales. En respuesta esto, aplicación coagulantes hierro aluminio son primera opción el tratamiento aguas residuales. No obstante, uso abundante es objeto discusión posible afectación al ser humano. Por tanto, presente artículo destaca últimos avances campo coagulación natural,...
The present study addresses an ecofriendly solution to treat automobile service stations effluents with high concentrations of oily substances, surfactants, organic matter and heavy metals.Bioadsorption using sawdust from pine trees, sugar cane bagasse coconut coir without any chemical modification removed colloidal contamination up 70%.Polyaluminium chloride, ferric chloride polyacrylamide were applied remove dissolved pollutants under saline conditions change initial pH.Both bioadsorption...
Uno de los aspectos medioambientales alto impacto en las industrias lácteas es la descarga aguas residuales, tanto por materia orgánica contaminante como considerable generación efluentes.

El sistema capacidad 55 L cada lote consistió tres biofiltros serie clarificación asistida zeolita activada. La degradación alcanzó...
Efluentes de la industria textil no solo representan un riesgo latente para biodiversidad en nuestro planeta sino también el ser humano debido a contaminación generada por colorantes industriales. En presente estudio se evaluó proceso Fenton decoloración agua contaminada con amarillo 160, azul 81 y rojo 190 una concentración inicial 3300 mg.L-1 demanda química oxígeno 1719 mg O2.L-1. Cambios pH dosis molares sulfato ferroso peróxido hidrógeno fueron evaluados. El permitió 99,9% remoción...
The treatment of domestic and industrial wastewater is a source for large number airborne microorganisms, which can be released at the environment during mechanical aeration.A meta-analysis up to 14 municipal plants was performed determine bacterial count in bioaerosols, as well antibiotic resistance, different stages (pretreatment, primary, secondary tertiary treatment), comparison with counts ambient air surrounding plants.The highest contamination microorganisms observed raw sewage inlet...
ABSTRACT This study investigates the application of electrocoagulation for enhancing biodegradability organic matter in automobile service station wastewater, notorious its contamination with polyaromatic hydrocarbons, heavy metals, and surfactants.
