1. SBR Sequential Batch Reactor

2. Activ sludge oMostly used method of treatment sanitary waste water oOrganic polution converts in to sludge by micro-organisms oMickro-organisms are suspended in water oBiological purification are going on in reactor

3. Activ sludge

4. SBR oSequencing Batch Reactor oUse ACTIV SLUDGE in process oRespectively repetitions of water treatment cycles

5. SBR – system of operation oCycle of water treatment consists of: oFilling oReaction oSettling oDecanting of treated water o(Idle/separation of excess sludge)

6. SBR – system of operation Settling Idle/Separation of excess sludgea Decanting Filling Reaction Efluent Slud ge Waste water Slud ge Start End

7. SBR – advantages of system oHigh efficiency of treatment oFacilities of small and midle size (few 10.000 PE) oFlexibility oRemoval of Nitrogen compounds by nitrification-denitrification process

8. Thanks on your attention!!!
