Have you ever wondered how nitrogen in domestic wastewater is biodegraded in an onsite wastewater treatment system?  The nitrogen cycle plays a key role in nitrogen removal from domestic wastewater, requiring specialized processes and equipment to complete the treatment process.  This presentation uses a multi-media format to cover the elemental steps required to complete the decomposition pathway within an onsite wastewater treatment system.  Discussion topics include the basic elements of wastewater chemistry, microbes, and chemical treatment processes. The session will begin with an informative video on the nitrogen cycle, followed by an explanation of the associated nitrification and denitrification concepts.
