01/04/2009  Sludge water is the waste wash water from concrete mixing plants and agitator trucks. With the growing demand for ready-mixed concrete, the disposal of sludge water is becoming an increasing environmental concern. Each working day approximately 700–1300 l of wash water are required for a single concrete truck (Sandrolini and Franzoni, 2001).
