Water and Wastewater Engineering

Abstract

Water and wastewater engineering are essential for public health and environmental protection. It involves the design, construction, and operation of systems to treat water and wastewater. The basic principles of water and wastewater treatment include physical, chemical, and biological processes. Engineers consider the nature and concentration of contaminants, the desired level of treatment, the cost of treatment, the availability of land, the climate, and environmental regulations when designing water and wastewater treatment systems. Common types of water treatment systems include conventional treatment, reverse osmosis, electrodialysis, and ion exchange. Common types of wastewater treatment systems include primary treatment, secondary treatment, and tertiary treatment. Critical tasks involved in operating and maintaining water and wastewater treatment systems include monitoring and adjusting the operation of treatment processes, conducting maintenance and repairs, and sampling and testing water or wastewater.
