The sludge drying bed is covered by an openable pitched roof utilising a breathable, waterproof, black membrane as roof material for ventilation, heat absorption and surface water runoff The sluice door contains alternating plates to facilitate the filling of the sludge drying beds and the decanting of the water at multiple levels within the sludge, with a sump located at the front wall to facilitate the efficient removal of the dried sludge from the beds. A telescopic handle, sludge drying bed cleaning tool is provided to facilitate the cleaning and maintenance of the sludge drying beds. |
