Abstract
Paper industry is one of the most popular industries that consume large
quantities of fresh water, in order to widen the range of water used for
irrigation and to achieve safe disposal to the surface water, application of
physical, chemical, and biological treatment technologies became an
essential need. Many technologies can be applied to perform biological
treatment but the sustainability and the effectiveness of Fenton technology
made it the most suitable between all treatment technologies. A laboratory
scale-pilot consist of four tanks with dimensions of 60×30×30 cm was
established as a simulation of the biological treatment process. The pilot
began with a primary sedimentation tank followed by a Fenton where
H2O2 was added to perform the chemical treatment, after that water was
fed into an aeration tank followed by a final settling tank to remove
inorganic substances produced from the treatment process. Four trials
were performed, the first trial was the activated sludge process as a control
process, the second trial was performing Fenton process without any
biological treatment process, the third trial was performing Fenton process
as a pre-treatment stage of the activated sludge process, and finally
activated carbon filter was added after Fenton process. Results showed
that Fenton technology was effective and promising technology as it
achieved TSS, BOD, COD, TKN, and TP removal efficiency up to 95.4%,
92.7%, 93.7%, 90.5%, and 91.7%, respectively during trial 4. The
previous removal efficiency provided the effectiveness of Fenton process
in reuse the paper industrial wastewater for irrigation purposes.
