Trickling Filter
A Trickling Filter is a common water cleaning system used in wastewater treatment plants. Think of it like a giant filter bed that water flows through, similar to how a coffee filter works, but much bigger. As water trickles down through layers of material (usually rocks or plastic), helpful bacteria grow on these surfaces and clean the water by removing waste materials. It's one of the oldest and most reliable methods for treating wastewater, and job candidates with experience in this technology are valued for their ability to maintain and optimize these systems. When you see this term in a resume, it indicates hands-on experience with wastewater treatment processes.
