Wastewater Treatment Applications

Wastewater Treatment

Wastewater Treatment

Wastewater treatment plants vary in design to meet federal, state and local regulations. Most facilities have similar equipment and applications for desiccant breathers. Typical applications include lubrication reservoirs on wastewater pumps, gearboxes and hydraulic systems. Pumps move wastewater step by step throughout the process. Gearboxes are found on equipment such as rotating biological contactors (RBC), clarifiers and conveyors.

Most of the processing equipment is located outdoors, subject to the high humidity in the area and exposed to extremes of weather.

This gearbox is located at end of a rotating biological contactor (RBC). Inside are panels or media discs which support the process of breaking down solid waste. An Air Sentry® X-100 desiccant breather was chosen for this application to help extend the useful life of the synthetic lubricant. Compared to other brands, the check valve design may double the life of the silica gel desiccant. Moisture blocked by the breather is adsorbed, causing gold to green color change, making it easy to see when it is time to change out the breather.
