Note 1: System settings have been derived from Prüfinstitut für Abwassertechnik-RWTH Aachen Final Test Report for RHEBAU Zons Aquastar SBR
System September 2004. Testing of the RHEBAU Zons Aquastar SBR System was carried out in accordance with EN 12566-3. The design is based on
DIN 4261-2: 1984 Small sewage treatment plants; plants with sewage aeration; application, design, construction and testing, using the influent loadings
stated above.
Note 2: ‘PE’ refers to the population equivalent.
Note 3: The system settings are initially configured for the design PE, and should subsequently be adjusted, during servicing, to accommodate the actual
hydraulic and biological loading on the system.
