The Cleaning Cascades clean substances that are heavier than water according to the sedimentation principle. For this purpose, natural gravity is used, whereby the solid particle settles to the bottom, as it has a higher density than the process liquid (water). To improve the cleaning effect, the cascade filters are divided into several chambers, which calm turbulence caused by currents.
When designing cascade filters, it should be noted that the total volume of the cascade should be at least seven times the hourly water throughput. If the cascade is only used sporadically and for a short time, the water throughput can also be increased.
