Investigation of the possibilities of dewatering sewage sludge by the method of electroosmosis in order to prevent land littering

Wastewater sludge from industrial enterprises is disposed of at disposal sites. This leads to a negative impact on the soil cover. The well-known methods of dehydration of moisture-containing materials have been studied. The chemical composition of sewage sludge was investigated. A technical solution for reducing the volume of wastewater sludge formation is considered on the example of cardboard and paper production. An electroosmotic installation is proposed. To study the process of sludge dewatering, a series of experiments was carried out on the installation with variable parameters of the voltage between the electrodes. A model of the particle velocity in the medium under study was presented. It has been proven that with the help of an electroosmotic device, up to 70% of moisture is effectively removed from the volume of waste sludge waste. This makes it possible to significantly reduce their volumes, reduce areas for possible or temporary placement and reduce the environmental load on the environment.
