Abstract

This paper provides a brief review of main characteristics of sludges of the transport industry containing oil suspensions of inorganic, metallic and non-metallic origin and surface-active detergents. As a result of in-situ and laboratory investigations, a general treatment system and two new sets of equipment, a tangential settler and a special filter block are proposed for the treatment of that type of waste waters.
