Lecture

Organic Micropollutant Treatment: Plants in Operation

In course

ENV-509: Applied wastewater engineering

This course on applied wastewater treatment focuses on engineering and scientific aspects to achieve high effluent water quality and to handle wastes and air emissions generated in wastewater treatment plants. ...

Description

This lecture covers the operation of wastewater treatment plants using activated carbon and oxidation processes to remove organic micropollutants. The instructor explains the transportation, application, and regeneration of activated carbon, as well as the challenges and costs associated with sludge treatment. The lecture also delves into the design and operation of ozonation plants, emphasizing the importance of efficient ozone transfer and reaction kinetics. Case studies of Swiss wastewater treatment plants using ozonation and activated carbon are presented, highlighting the considerations for industrial wastewater treatment and the optimization of treatment processes.

Wastewater treatment

Wastewater treatment is a process which removes and eliminates contaminants from wastewater and converts this into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation). The treatment process takes place in a wastewater treatment plant. There are several kinds of wastewater which are treated at the appropriate type of wastewater treatment plant.

Sewage treatment

Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from.

Industrial wastewater treatment

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants.

Water treatment

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.

Secondary treatment

Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option. A "primary treatment" step often precedes secondary treatment, whereby physical phase separation is used to remove settleable solids.
