摘要：The article characterises most frequently selected by investors individual mechanical and biological sewage treatment systems. On the basis of gathered information and technical documentation, technical and technological analysis of the devices was conducted. Assess factors include technology, structure, workflow, control, exploitation conditions, and sewage treatment system effectiveness. On the basis of conducted analysis, limited possibility of using activated sludge wastewater treatment in a flow system was established due to the difficulty of stabilizing the whole system. An optimal solution for individual wastewater treatment system are solutions of activated sludge technology in SBR system and hybrid technologies.
