    Sludge drying beds and lagoons Sludge Processing

    Drying bedsare uncomplicated in design and operation, since they involve simply spreading the sludge as a thin (up to 300 mm) layer over a porousbedofsandand gravel. The water is then allowed to drain through thebedand into a network of embeddeddrainagepipes to allow it to be collected.

    There are mainly five types ofsludge dryingmethods viz. conventionalsand beds, paveddrying beds, artificial mediabeds, vacuum assisted and solar. The typical conventional SDB has dimensions of 6 m width, 6 - 30 m length, withsandlayer ranging from 230 – 300 mm depth. Thesandshould have a uniformity coefficient of not over 4.0 and effective size of 0.3 to 0.75 mm.

    In principle the construction of unplanted drying beds is similar to gravel/sand filters. The bed frame is usually made from concrete or a plastic liner with the bottom surfaces slightly sloped in order to facilitate percolation and drainage. The drainage pipes are covered by 3-5 graded layers of gravel and sand.
