In addition to protecting against external contaminants, dust wiper seals also help retain lubrication within the system. By preventing dust and dirt from entering the system, these seals help reduce friction between moving parts, which can prolong the life of the equipment and reduce maintenance costs. Proper lubrication is essential for the smooth operation of hydraulic cylinders, pneumatic systems, and other machinery, and dust wiper seals play a vital role in ensuring that lubricants stay where they are needed most.

Coagulation is another vital process in water treatment. This involves the addition of chemicals like alum (aluminum sulfate) or ferric chloride, which help to clump together (or coagulate) small particles and impurities in the water, making them easier to remove during the sedimentation process. This chemical reaction reduces turbidity and can significantly improve the clarity and quality of the water.
