Wastewater treatment is one of the most important global industries, ensuring the health of millions. The multi-step treatment process includes many stages of filtration, clarification and disinfection of wastewater made possible by heavy-duty machinery that is subject to harsh environments. Removing contaminants and separating wastewater into various barrels is a continuous process that relies on rotating components during each stage and bearings play a vital role in every step of the water treatment process: Intake, Rapid Mix, Flocculation, Sedimentation, Storage, Disinfection and Filtration.

Avoid downtime, water contamination and promote the smooth operation of machinery by investing in low-maintenance bearings. Ceramic, stainless steel, and/or engineered thermoplastic components are used in many of the processing and treatment machines and generally perform best under the harsh, wet & dirty conditions of wastewater treatment. Be sure to choose bearings of the highest quality to keep pumps, drives and valves in municipal wastewater treatment plant working efficiently 24 hours a day, 7 days a week.

These bearings offer all the advantages of traditional bearings, but with easier assembly. The half split design allows for easy installation, inspection and replacement since you do not have to remove or disrupt other machine elements.

Split roller bearings help keep large solids out of machinery, making them best for sand and grit removal, clarification, aeration and more, including belt presses. Split roller bearings allow easy accessibility and maintenance of the bearing.

Commonly found in submersible pumps, seals and O-rings provide further barrier protection and are able to keep out water and other potential contaminants.

Another commonly found component in submersible pumps that operate on and with drives, shaft grounding rings are often associated with electric discharge machining (EDM) and eliminate fluting concerns.
