New technology Enhances Miami Wastewater Treatment Plant Efficiency

PCL recently completed work on a new vacuum pressure swing adsorption system at the 143-million-gallon-per-day Central District Wastewater treatment plant in Miami.

The system is a first for the Miami-Dade Water and Sewer system and replaces a cryogenic oxygen system. According to PCL, the newer technology reduces plant power consumption while generating the same amount of oxygen, allowing the facility to produce pure oxygen more efficiently and cost-effectively and assisting Miami-Dade County in meeting new environmental guidelines set by the U.S. Environmental Protection Agency and the Florida Dept. of Environmental Protection. Because the original treatment plant was not built to accommodate expansion, the construction team relocated existing electrical duct banks to free up the footprint for the new facility. PCL’s scope of work included electrical, instrumentation and controls; site and civil work; process mechanical; architectural; structural; plumbing; HVAC; and fire protection, according to the company.
