| Title of the article | The cleaning of stability «oil-water» emulsions by cyclic electroneutralization method |
| Abstract. | Problem statement. The waste water containing organic impurities of «oil-water» type emulsions are typical for most enterprises and for building industry too. To clean such wastewater with stable emulsions is particularly difficult. For the treatment of such wastewater, complex treatment or neutralization systems are used, associated with the complexity of maintenance and high economic costs. Used for the treatment of wastewater from emulsified contaminants – the electroneutralization method shows very good results for emulsions with a moderate degree of stability, but it turns out to be ineffective for stable emulsions. In this regard, it is necessary to search for options for the further development of the method of electroneutralization in relation to stable emulsions. Results. Analysis of the results obtained using installations with multi-electrode systems showed that the use of such installations, both with vertical and horizontal electrode systems, with an increase in the number of electrodes, ceteris paribus, leads to an improvement in cleaning efficiency. This is explained by the role of the contact effect. However, an increase in the number of electrodes leads to an increase in the size of the installation, which increases its cost, footprint, and service conditions. In this regard, the cyclic processing method was investigated using an additional clarifier. It turned out that the cyclic treatment dramatically increases the degree of purification, even when using fairly stable emulsions. Conclusions. Based on the results obtained, it can be concluded that the cyclic version of the use of the electroneutralization method can be used to purify wastewater from organic pollutants forming stable oil-water emulsions. The cyclic method can be used both in combination with an additional settling tank, and when using separate installations. This method can be used both in the construction of sewage treatment plants and in wastewater systems. |
