    Sludge Dewatering an overview ScienceDirect Topics

    Since transpiration is a dominant process in STWs, plant function is crucial for sludge dewatering. Plants could significantly increase ET values up to 35% in an STW compared to unplanted sludge drying beds (Stefanakis and Tsihrintzis, 2011), since common reed (Phragmites australis) possesses a high transpiration capacity (Outwater, 1994; De ...

    The piping to the sludge drying beds should be designed for velocity of at-least 0.75 m/s (TCHOBANOGLOUS et al. 2003). The sludge is placed on the bed in 20–30 cm layers and allowed to dry. Sludge cake removal is manual by shovelling into wheel-barrows, trucks, scraper, or front-end loader. The drying period is 10–15 days, and the moisture content of the cake is 60 – 70%.
