الملخص الانجليزي
Organic matter (OM) is commonly occur in freshwaters, and it poses a threat for health
and environment. For instance, high OM concentrations increase the sludge volume and cost of
the treatment process in turn. Remediation of water or wastewater from OM has thus become an
important issue for the treatment industry. Electrocoagulation (EC) is one of the preferred
techniques of treatment for remediation of water from OM and other polluting chemicals, as it
utilises simple and easy to run machines and tools, it requires less working area in comparison
with conventional methods, and it is more rapidly pollutant separation than other methods. EC
technique could be described by passing an electric current through sacrificial electrodes to
produce metal hydroxides that separate dissolved contaminants from aqueous phase. On the
other hand, the EC method has a limited efficiency in the treatment of high OM concentrations.
The present study is thus intended to develop a new technique that combines an EC reactor with
an ultrasound (US) field to remediate water from OM. The EC reactor, in this study, was made
from four aluminium plats (500 cm2 in gross area) and plastic container (1 L in volume). The
operation of this combined method was optimised for the effects of key factors, such as the pH
of solution, electrodes gapping, and current density. The obtained results proved that the US-EC
technique removed 97.50 % of OM after 5.0 minutes of US irradiation, 20 minutes of
electrolysing at current density 4.0 mA. cm−2, initial pH 7 and gap between electrodes 5.0 mm.
