An Introduction to Control and Chemical Feeding for Wastewater Treatment

COURSE NO: C02-051
An Introduction to Control and Chemical Feeding for Wastewater Treatment
Course Highlights

This online engineering PDH course presents criteria on metering, instrumentation, controls, and chemical feeding devices used in wastewater disposal systems. Specific design problems may require departures from these practices; therefore, use these criteria with discretion.


For example, use of computers and microprocessors for data logging, indication, and process control is considered an emerging technology. This technology is presently primarily applicable to large wastewater treatment plants with adequately trained staff to maintain the hardware (greater than 10 Mgd size). However, improvements in electronics, hardware, software, and sensing devices (primarily sensing elements) will make this technology more desirable for smaller plants. Detailed information is not included for such emerging technology because of its state of rapid change and because additional development and application experience need to occur before application to the smaller facilities is justified.


This 2 PDH online course is intended for engineers and other design and construction professionals seeking an introduction to the process technologies, equipment and design practices for controlling and chemically treating industrial and oily wastewater.
