5.6 Equalization Tank (TNK-301) Module

A schematic of the Equalization Tank (TNK-301) is located on the EQ & PRE-ANOXIC HMI
screen and shown below.

5.6.1 Function

The EQ Tank (TNK-301) buffers variability in the influent flow rate to maintain a consistent flow
rate through the membranes and to reduce concentration fluctuations of influent constituents
(i.e. BOD, TSS etc.) through the MBR treatment system. Wastewater entering the newterra
MBR will first have undergone pre-treatment by fine screens and grease traps (kitchen waste).
The waste water is then pumped to the Pre-Anox Tank.
