Sewage Sludge Dewatering Process Using Liquefied Dimethyl Ether as Solid Fuel

Malaysia expected to face serious problem in sewage sludge disposal in the next few years if this problem is not properly manage and well treated. The common way of sludge disposal in Malaysia is to dispose it on the land, by landfill disposal. However, most of the landfill has been closed since reaching it capacity. This product required innovation and advance solution for treatment and disposal since the production of sewage sludge rapidly increasing and the available solution for their disposal is out dated .One of the ideal solution to dispose the sludge is by converting it into useful energy in the form of solid fuel such as pallet and briquette and burn it as a solid fuel to generate power. However, the main problem faced is it contains high moisture content which is more than 90% of moisture content. In order to convert it into useful energy, the moisture content of the sludge need to be reduced into acceptable level which is below 20% . One of the effective methods to remove the moisture content is by using a thermal dryer. The preliminary results from this study found that the thermal dryer produced 63.32kg/h of dried sewage sludge with moisture content less than 20% . The production rate of this dryer shows positive result and with continuous production, this dryer cable to dry tons of wet sewage sludge.

Abatement Strategy

Sludge agriculture application in future will be one of the main sewage sludge disposal ways in China. To ensure safety and environment of sewage sludge agriculture application, except to strengthen the research of sludge heavy metal, pathogen outside the organic contaminants will be one of the focuses of the future research, especially to strengthen the PAHs and NP/NPE. In order to reduce the environmental risks of sludge agriculture application, using biological aerobic fermentation processing technology treatment sludge can effectively reduce the organic contaminants, depress secondary pollution problem, which sewage sludge brings.
