A Study on Automatic Sludge Discharger of a Water Tank of Intermediate Treatment Contractors of Construction Waste

Abstract:

While an intermediate treatment contractor of construction waste extracts renewable fuels from construction wastes, water is stored in a water tank and a considerable amount of sludge remain in the water. In this respect, the present study designed an apparatus to automatically discharge sludge from the water tank. The discharging process of the apparatus is as follows: it sucks sludge along with water of the water tank into a storage tank. Sludge and water stay for a certain time period until the former settles. And water drains out from the storage tank, being separated from sludge that still remains in the storage tank. The amount of sludge to discharge depends on its storage time in the tank. Therefore, the duration of settlement was measured to find an optimal time. Discharging test was repeated. An impeller was installed on top of the storage tank to know how it affects sludge settlement. Using the collected data, this study confirmed the factors necessary for smooth discharging of sludge.
