The OPS^® operations/control center (1) contains the air pump, control panel and alarm horn and light for the unit.

Wastewater enters the system at the Inlet (2) and begins the treatment cycle in the Aeration Compartment (4). Air is pumped from the Air Pump (1) through the Air Distribution Manifold (7), the Flexible Air Lines (9) and out into the Aeration Compartment (4) through the patented triple Anchored Diffuser Assemblies (10). Here the air mixes with the wastewater and the aerobic bacterial colony flourishes, treating the wastewater.

As the treatment cycle produces digested effluent, the mixing action produced by the diffusers causes the effluent to enter the Clarification Compartment (5). The conical shape of the Clarification Compartment causes most remaining suspended solids to drop out the bottom and re-enter the treatment cycle in the Aeration compartment.

As additional wastewater enters the system via the Inlet, clarified effluent is then pushed by hydraulic action out of the Clarification Compartment through the Outlet (8), where it enters to the effluent disposal system of choice.

The alarm system in the OPS^® is activated by the High-level Float if the system becomes too full (volumetric overload) or by the control panel if air pressure drops to an unacceptable level. Your factory-trained service technician should be called if the alarm sounds. He will enter the system through the Offset Service Access (6) and diagnose the problem.
