is one of the important treatment methods used to remove colloids from
wastewater. Dyestuffs are the leading source of colloids in wastewaters.
Dyestuffs, which are used extensively in the textile industry, become important
colloidal pollutants for the receiving water environments, given the increased
amount of water used by the industry. In this study, the effect of molecular
weight of pollutant colloids on the removal efficiency of electrocoagulation
was investigated by using two different textile dye materials with different
molecular weights. For this purpose, color removal studies were carried out in
the reactor where aluminium electrodes were used. The study was carried out at
different pH values ​​and the effects of different flock structures (size) were
also studied. It was found that the pH a was more affected than the dye having
a larger molecular weight. The Reactive Black 39 (1021.16 g / mol), which has a
higher molecular weight in the dyestuffs, has Remazol Red 3B (674.10 g / mol),
which has a smaller molecular weight, while being affected by a change of pH
from 75% to 74.83% </span> <span style="font-size:18px;"> It is affected by 13%, down from
