English Abstract
Industrial wastewater treatment and management in Palestine is very limited.
One of the larger seasonal industrial wastewater is olive mill wastewater (OMWW), the total amount of OMWW which produced in the West Bank is about (120000) cubic meter annually.
OMWW had no pre-treatment or any type of treatment, all of this heavily polluted wastewater discharged into Wadi or into sewage network without permissions.
These discharges could be the major sources of groundwater pollution or make a disturbance in WWTP operations.
The main goal of the research was to evaluate the operation stress on a pilot scale MBR system under normal and compare with heavy polluted (OMWW).
The following objectives are investigated: - Investigate the process performance and reclaimed water quality under normal operational conditions, the baseline data.
- Study the influence of stress conditions on the MBR operational performance.
- Investigate the impacts of toxic loading (phenols and COD) from olive oil mill wastewater on MBR process performance and removal rates of COD and nitrogen.
This research was accomplished by integrating a comprehensive data collection and analysis with a technical field work.
For phase one sample is collected each week and the second phase two samples were taken every week.
The wastewater used for this study was formed Birzeit University Campus, which has low organic loading comparing with domestic wastewater (BOD 248 mg\L, COD 479 mg\L), and olive mill wastewater is fresh one collected from three phase method extraction olive.
Under normal and highly loaded conditions the removal rate was sufficient as treated technology flat sheet MBR was used There is comparison between the removal rates for normal and abnormal conditions for these parameters COD, BOD, TSS, NH4+, TKN and total phenol, the removal percentage was (94%, 90%, 93%, 93%, 71% and 98%), removal percentage for highly organic load conditions COD reduce by 35%, BOD almost 50%, TSS and NH4+ unchanged with 93%, TKN almost unchanged, but total phenol reduced by 9%.
According to these analytical results of MBRs the effluent quality of Pilot scale is complying with set local effluent limits for agricultural irrigation grade (A) also, it has a good process performance of diluted OMWW treatment.
The flux of the MBR was affected after the OLR became higher exponentially, which is reduced 0.43 to 0.087 L/m2.d, as a result of increased trans-membrane pressure increasing.
Statistical analysis shows that HRT and MLSS the most important parameter effect of MBR fouling.
This study could help MBR WWTP operators to predict and control the MBR fouling according to operation parameters.
Although, future studies can use the results of this thesis to identify a useful data about the monitoring and evaluation MBRs
