Sludge Drying Bed Design Review EPA

Sludge Drying Bed Design Review EPA

----- INTRODUCTION The sludge dewatering system most commonly used in small wastewater treatment facilities is the sand drying bed. Insufficient drying bed capacity can severely limit the capability to remove excess activated sludge from the biological treatment processes which, in turn, can limit the treatment process performance.

Drying air. The drying air is heated to an inlet temperature of 120-150 C. The air flows through the sludge layer, absorbing the moisture from the product. To achieve optimum thermal efficiency, the dryer is operated with a high recirculation rate. Thus, a large amount of the drying air is recycled to heat generation and heated again.

Influence of Valorization of Sewage Sludge on Energy

Valorization of digested sewage sludge generated in a medium-sized sewage treatment plant and the effect of valorization on energy consumption during sludge drying used for energy recovery are presented. Anaerobic digestion of sewage sludge reduces dry matter content compared to raw sludge. This lowers its calorific value leading to the lower interest of consumers in using it as fuel.

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%.
