Purification of agro-industrial wastewater from the grease-protein mixture by means of electroflotocoagulation

Abstract

The process of agro-industrial sewage treatment with the aim of extracting grease from the waters is studied by means of electroflotocoagulation. A method of optimising the construction of electroflotocoagulation apparatus for sewage treatment is offered that allows passing from a laboratorial model to an industrial specimen that possesses the same level of technological characteristics. Multiple examples are given of applying electroflotocoagulation technology for sewage treatment from proteins and grease under different conditions.

Electrochemical removal of pollutants from agro-industry wastewaters

“…In fact, the flocculating polymer improved the stability of the flocs. This facilitated easy recovery of flocs and enhanced rates of sludge sedimentation [26]. Fe 2+ ions were produced by anodic dissolution, whereas ferric ions (Fe 3+ ) were obtained by chemical oxidation of ferrous ions in the presence of dissolved oxygen [12].…”

Treatment of municipal solid wastes leachate by means of chemical- and electro-coagulation

“…Electro-chemical technology became an inevitable treatment step for the resistant contaminants in wastewater [12]. Especially, it is used efficiently in the treatment of textile [13], food [14,15], metal and galvanization [16], and petrochemistry industry [17,18] effluents.…”

Electrodissolution of Aluminum Electrodes in Electrocoagulation Processes

“…During the last few decades, electrochemical wastewater treatment technologies have undergone rapid development. One of these technologies is the electrochemically assisted coagulation that can compete with the conventional chemical coagulation process in the treatment of wastes polluted with colloids or macromolecules or in the treatment of emulsions. − …”
