Columbia Metro WWTP Aeration Improvements Columbia, South Carolina
The Columbia Metro Wastewater Treatment Plant project included the construction of a new blower building, consisting of six new blowers, new switchgears, and stainless steel air header piping. The work also included constructing a new magnesium hydroxide facility consisting of four new bulk chemical tanks with mixers and a new chemical pump room with metering pumps, as well as electrical and instrumentation packages. After demolishing the existing aeration mixers, Aeration Basins 1 and 2 were refurbished to install fine bubble diffusers. Upgrades were also made to the electrical distribution and SCADA monitoring systems throughout the site.
