Study of the Trimethylamine Removal Capacity Using Mineral-Based Activated Carbon (Curanilahue, Province of Arauco) and Future Projections

There is no translation available.

   A hybrid material of activated carbon and MOFs is proposed for the adsorption of trimethylamine (TMA) emitted by the fishing industry, achieving complete removal in the aqueous phase.

   Efforts focus on optimizing its surface area and selectivity for effective application under real conditions, contributing to environmental impact mitigation and improving the quality of life of nearby communities.

Design of a Ventilation System for Odour Mitigation – Grit Removal Stage of a Wastewater Treatment Plant Using Computational Simulation

There is no translation available.

   This study evaluates a push-pull ventilation system with localized extraction designed to reduce H2S concentrations in the settling stage of a wastewater treatment plant in Santiago, Chile.

   CFD simulations and field measurements show that the existing crossed ventilation system results in H2S concentrations up to 21 mg/m³ over the water surface. The improved push-pull system effectively lowers H2S levels in the plant corridors to below 7.5 ppm, complying with Chilean regulations.

Reduction of Pollutant Emissions in the Agri-Food Industry: Implementation of the Ubiproc® Biological Filtration System

There is no translation available.

   The agro-industrial sector generates emissions of gases such as methane, ammonia, and hydrogen sulfide, which affect air quality and contribute to climate change.

   The Ubiproc® system employs biological filtration through microbial biofilms in closed organic waste pits, combined with real-time gas monitoring to optimize management. Field trials demonstrated maximum removal efficiencies of 87% for ammonia and 70% for hydrogen sulfide, with consistently stable average performance throughout the operational period.
