Lecture

Nitrogen Cycle in Water: Denitrification and Precipitation Processes

Description

This lecture discusses the impact of excessive atmospheric nitrogen inputs on aquatic ecosystems, focusing on denitrification as a process to reduce nitrates. It covers the biological nitrification denitrification process, denitrification tank sizing, and the precipitation of phosphorus. The importance of proper denitrification tank dimensioning and the simultaneous precipitation of phosphorus with iron are highlighted, along with the production of metal hydroxides during the process. The lecture also touches on the dosing station for sewage sludge ash storage and its role as recyclable material.
