SBR reactor
Why apply SBR systems
as decentralised plants in arid areas?
 the SBR proceeding can be adapted to nearly all
decentralised applications / conditions
 further developments of the SBR proceeding are
reduced to a simple, efficient technology and
consume only little energy
 these proceedings assure solid purification processes
and very regular outflow conditions
– therefore they are ideal for further
proceedings for a water reuse, “a must in arid areas”
