The Treatment Plant Laboratory

The Administration Building and Laboratory

The plant laboratory is housed in the site Administration Building which also contains the site administrative offices.

The laboratory contains the latest state of the art laboratory facilities and is where a vast range of tests are carried out on the various phases of the treatment process to ensure the plant is in compliance with all the state, local and national wastewater discharge regulations.

The laboratory technician Mr. Woody Hillis who reports to the Chief Operator, carries out the daily laboratory work and the running of the laboratory. This work is critical to the operation of the plant. The accurate test results allow the chief operator to make sound decisions on changes needed to keep the plant in compliance with its NPDES permit for the discharge of wastewater from the plant.

Settable Solids Test

Polymer Blend Unit

 
The Settable Solids Test, is a test that represents what is happening in the plant  clarifiers. As can be seen, the solids settle to the bottom and the clear water rises to the top.

The Polymer Blend Unit, which is located in the Bio-Solids Building, is were polymer is mixed with water before injecting it into the sludge (bio-solids). The polymer causes the solids to clump together which assists in the separation of the solids from the wastewater. Among the various tests carried out in the laboratory are tests which determine the concentration of polymers which are added to the wastewater in this process.
