Combi-Clear-Water system 

The Combi-Clear-Water system (CCW) is a combination of a Sequencing batch reactor (SBR), reed bed treatment and sludge dewatering system in one construction.

The SBR-system is based on the conventional aeration system for waste water treatment (activated sludge process). The different processes: Mixing (denitrification), aeration (carbon removal and nitrification) and settling takes not place in different chambers but in a firmly defined cycle in only one chamber. The processes are running one after another in three phases: Filling, reaction, sedimentation.

After the complete treatment process is completed the clarified water is discharged intp the secondary treatment step. This water percolates through the sand filter of the reed bed treatment system and drains into a special storage tank underneath. The stored clean water can be used for irrigation etc. or discharged into a river.

The accumulated sludge of the primary treatment step is pumped onto the sludge dewatering bed next to the SBR. This special combined system is especially appropriate for the use in areas with little space.
