Effluents from many industries are one of the major sources of water pollution and represent important environmental problems. Generally, paper recycling process generates large amounts of wastewater.Electrocoagulation (EC) is an evolving technology that has been effectively applied in the treatment of industrial wastewater containing various pollutants, such as textile wastewaters or chemical mechanical polishing wastewaters. This technique has a great ability to remove the pollutants from water due to its high efficiency, economically attractive and relatively lower sludge formation compared with other conventional processes such as biological, physical, chemical, adsorption and advanced oxidation processes. However, electrocoagulation (EC) process has been proposed as alternative to biological, physical and chemical methods due to its environmentally friendly and cheap to operate. This paper presents the experimental results obtained by applying the electrocoagulation method for removing the organic pollutants (COD) and total suspended solids (TSS) from wastewaters generated in the paper mill that use as raw materials recycled papers.
