Abstract—Greywater is the major part of water consumption
in houses. Greywater should be treated to complying with the
specifications for several purposes such as toilet flush,
landscaping irrigation, and agriculture. The treatment
efficiency of both MBR and RBC systems was investigated by
using a verified mathematical model. The simulation program
GPS-X (version 6.0) was used to simulate both MBR and RBC
systems. The simulation model for biological treatment for both
MBR and RBC systems is based on Activated Sludge Model 1
(ASM1). The experimental data for model calibration and
verification for the MBR system were taken from experimental
work done at Tubitak, Marmara Research Center, Turkey
ATASOY. As well as the RBC proposed model was verified also
by using RBC experimental results for a pilot plant according to
BABAN. The RBC pilot plant consists of three units, The first is
the RBC unit, the second unit is the settling tank and the last
unit is the disinfection tank. The results of the MBR plant
showed that the removal efficiencies of the greywater were:
95% for COD; 95% for BOD5; 96% for TKN; 92% for NH4+
and 99% for TSS. Whereas, the results of the RBC show that,
The BOD efficiency removal was ranged between about 93.0 to
96.0 %, and for the total SS removal was ranged between 84.0 to
95.0 %. The MBR system provides complete nitrification and
suspended solid removal. The RBC system provides less
nitrification process and suspended solid removal. The effluent
of the rotating biological contactors units for the greywater
could be reused after filtration and disinfection with minimal
cost of operation. The effluent of the membrane bioreactor unit
needs only disinfection before reuse.
Index Terms—Membrane bioreactor, rotating biological contactors, greywater treatment, mathematical models, wastewater reuse.
