Study and Analysis the Mechanical Designing Process of Factor Attributes Towards the Propose Dewatering Devices in Wastewater Industry

摘要

In every year, the volume of municipal sewage has been increased due to increasing of population in Malaysia. The operation of municipal treatment should be gone for the larger scales for operation and disposal. The operation, the pre-treatment plant, post treatment plant until the suspended solid can be disposed to landfill or do some burning process to gain the methane gas towards to renewable energy. It has to meet the requirement by Department of Environment (DOE), which is by removing at least 90% of water from the suspended solid, focusing on the municipal sewage treatment. The wastewater industries need to have another alternative solution to for the time reduction of the drying process from the existing dewatering instruments or may have the new concept of the devices, which can easily help to remove the water from the suspended solid. Based on the pilot study from the industry, the dewatering bag as their chosen for the dewatering instrument. It is because of its huge of benefit such as cost. By designing a new portable dewatering device that will supply hot air to support the dewatering bag, so it will not only depends on natural heating element (sun), as a vital problem that have to be settled. So this paper presents the pilot data finding by comparing two dewatering bag, one by using the propose Universal Compress Air Fit (UCAF) and another one without it in real application. UCAF itself that supply hot air to the sludge can helps the sludge to dry 30% faster than usual.
