In sewers, storage sewers and storm water tanks flush cleaning systems are used to loosen contaminants that have accumulated on the bottom with a strog flush wave and to transport the contaminants to the treatment plant either by gravity or pumped.

Flush cleaning is a remobilistaion and transport process of settled sewage contaminants consisting of one or more flush waves that is used to clean storm water tanks and sewers. Flush waves describe an instationary state of flow with sudden increase of water level, flow velocity, flow and shearing stress.

The operating principle of flush cleaning systems is the use of a flush wave whose energy is large enough to surpass the necessary shear stress to strip and transport scalings and deposits. This energy is provided in form of potential energy, which is suddenly released by opening of the locking mechanism.

The factors flush lane length, bottom slope and width of the flush lane (pipe diameter for sewer flushing) define the size of the necessary flush water volume. This volume is provided either in integrated bins (tipping bucket), separate chambers/ reservoirs (flush gate) or in the sewer volume itself (arched gate). We use Flush cleaning systems because of their low energy consumption, high cleaning and transport performance and low maintenance requirements.
