In dissolved air flotation units, mechanical rubber scrapers push the float over a ramp called?

In dissolved air flotation (DAF) units, the area where the flotation solids are collected and pushed by mechanical rubber scrapers is called a "beach." The term "beach" refers to the sloped surface where the floated material accumulates and is then scraped off by these mechanical devices. This design allows for effective removal of solids from the water, enhancing the separation process as the flotative materials rise to the surface.

The use of the word "beach" in this context is specific to water treatment terminology, highlighting the area where the separation process culminates. This mechanism is critical in ensuring that the system operates efficiently by facilitating the removal of the solids that have floated to the top. The other terms, while they may refer to surfaces, do not specifically denote the operational context of where the float is gathered in this type of system.
