Description

Note: This course is part of a more comprehensive program titled: Water Treatment Mastery: Potable, Wastewater & Industrial, with a duration of 25.5 hours.Secondary wastewater treatment is the core of the biological treatment process, primarily aimed at removing biodegradable organic matter in dissolved and colloidal form. It also removes suspended solids that were not eliminated in previous stages, as they will form part of the floc and be removed from the system through excess sludge purge. Additionally, a certain amount of pathogens will also be removed, as the reactor conditions are not conducive to their growth.For the process to function correctly, the biological reactor must maintain certain controlled conditions, which will be described as each video develops.The Activated Sludge course covers the following topics: Treatment Train, Anabolism, Catabolism, Microorganisms and floc structure, Mass load, Sludge age, Volatile suspended solids concentration in mixed liquor, 30-minute sedimentation volume, Sludge volume index, pH, Temperature, Oxygen concentration and Oxygen consumption rate, Volumetric load, Hydraulic retention time, Recirculated flow and recirculation ratio, Sludge purge, Reactor inoculation, Color, Odor, Foam, Bubbling in the secondary sedimentation tank, Fat appearance. PROCESS VARIATIONS: Conventional Activated Sludge, Complete Mix, Decreasing Aeration, Stabilization-Contact, Extended Aeration.This course aims, without beating around the bush or overloading with technical terms, to directly introduce the purpose of the technology and how to operate it, using simple language to ensure clear understanding and improve the efficiency of your process.
