Abstract
Many industrial activities require large amounts of water and produce
highly polluted wastewater, which may cause severe environmental
pollution if they are released to the environment without any proper
treatment. Electro-flotation is a technology that combines the
conventional coagulation, flotation and electro-chemistry. Electroflotation
requires simple equipment, low initial investment, low
operating cost and requiring no chemicals.
The removal behavior of some heavy metal ions, dyes and suspended
metal particles were investigated in details. The pH was an important
factor during applying electro-flotation technique; the higher removal
was achieved at neutral pH for almost different kind of candidate
materials. The kinetics, mechanisms and thermodynamic parameters
were studied. The cell parameters such as current density, ionic
strength, stirring speed, current type, electrodes connection and inter
distance were also studied.
A simple designed electro-flotation cell prototype was employed and
suggested for treating different industries effluents. The treated
wastewaters met the International Standard for ”drinking or irrigation”
water. The operating costs for different industrial effluents was ranged
from 0.177 to 1 US$ per cubic meter depending on the effluent type.
