Abstract
A wastewater treatment system having an aeration tank (20) is provided with an operations control center (12) that includes a controller (64) and an aerator pump (50) mounted atop a base (58), which is in turn mounted atop a platform (56). A plurality of electrical lines (66) extend from the controller through respective conduits (90, 92, 94, 96). The conduits extend through and are sealingly engaged by holes in the base and the platform. A compression fitting (136) and coupler (154) are included to provide a fluid-tight seal. This arrangement is advantageous because it prevents corrosive gases from entering the operations control center and corroding the terminals thereof. Also described is a wastewater treatment system that includes a pretreatment tank (244), an aeration tank (20), and a pump tank (202) secured together by a connector that includes bands (260, 262) and spacing means (264, 268) for maintaining a fixed-spaced relationship between the tanks.
