E – 1285 Control & Chemical Feeding – Wastewater Treatment
Intended Audience: engineers and other design and construction professionals
PDH UNITS: 3
This publication contains 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 naval facilities is justified.
