| Title of the article | The electroneitralyzation cleaning of most water emulsions |
| Abstract. | Problem statement. Cleaning highly stable emulsions is the most difficult problem. Modern technologies are complex and costly. Of significant interest is the attempt to use the electroneutralization method for these purposes. This was motivated by the successful use of this method in other areas. Results. In this work, emulsions based on NGL 205 emulsifier and industrial oils with additives were used. It was found that a pre-chemical treatment is required for the most stable emulsions. The destruction of the stability of such emulsions can be achieved by a complex method. This method includes chemical treatment, the subsequent electrochemical treatment using electrocoagulation or electro-flotation and the final electrolyte neutralization treatment. Sustainable emulsions based on industrial compositions can be destroyed by electrically neutralization in a cyclic manner. In this case, two sedimentation tanks are included in the scheme. In the first clarifier, 40 % of the most unstable part of the emulsion is separated, as well as suspended substances. The second settling tank is used in the cyclic process of processing by an electrolytic neutralization method. The optimal conditions for the use of the electrolytic neutralization process, as well as various options for using such a scheme, have been determined. Conclusions. The value of the results obtained for the construction is that the developed technology can be used in the production of building materials and concrete structures using compositions that form stable emulsions, for example, in the lubrication of forms. The developed technology can be used for wastewater treatment of construction enterprises whose effluents contain emulsified contaminants that are not amenable to conventional purification methods, due to their increased stability. |
