The sewage sludge formed at wastewater treatment plants constitutes a small percentage of the volume treated wastewater. However, costs associated with and disposal account for lion's share operational expenses plants. contains harmful toxic substances. On other hand, is source carbon, nutrients, trace elements, meaning it can be effectively utilized. An important stage in its dewatering, particularly use electric current. study investigated electro-dewatering activated moisture content 98% from secondary clarifiers Ternopil plant using direct Experiments were conducted on laboratory setup U-shaped glass tube carbon rod anode cathode. effect field was observed during fading period, when, after significant amount water had been separated sludge, process slowed down. obtained results compared those graphite flat cathode, as reported by researchers. Electro-dewatering both setups produced practically same effect. It confirmed that dewatering current applied drying beds
