Lecture
This lecture covers the treatment and recovery of water and waste using mechanical and biological methods, including ventilation by natural chimneys, biological treatments, and composting processes. The instructor explains the different stages of composting, from pretreatments to the maturation phase, highlighting the importance of factors like temperature, aeration, and particle size. The lecture also delves into the anaerobic digestion process, discussing the biochemical reactions, reactor characteristics, and the production of biogas. Various aspects of compost quality, such as physical, chemical, and biological conditions, are explored, along with the practical applications of compost and digestate in agriculture and energy recovery.
