Impact Of Micronutrient Technology In Odor Control Of Wastewater Treatment Plants Of Pulp Mills

    The pulp industry faces challenges in balancing biological wastewater treatment with effective odor control.

   SciCorp’s micronutrient technology, based on plant extracts, selectively stimulates specific bacteria within biological sludge to significantly reduce emissions of malodorous gases such as hydrogen sulfide and mercaptans. Additionally, this technology enhances the biological treatment performance by increasing load capacity, lowering phosphorus concentration in the treated effluent, and reducing biosolid production, thereby optimizing overall wastewater treatment plant efficiency.

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

   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

   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.
