Surface preparation is a process of treating a surface to increase its attraction to coatings and imperative to ensure satisfactory coating can be attained. Conventional techniques of surface preparation usually involve blasting of abrasive material on the surface which usually associated with airborne debris and hazardous contaminant from the process. A relatively new technology in surface preparation is the usage of sponge media as an alternative to the conventional abrasive material. Being soft and elastic, sponge media can reduce airborne emission from surface preparation significantly while being able to be recycled. Unfortunately, the recovery of used sponge media becomes difficult during rainy conditions in which the sponge absorbs water and quickly becomes saturated. Therefore, this paper presents the drying characteristics of sponge media using a swirling fluidized bed dryer (SFBD) for rapid drying to overcome the long, inefficient sun drying as per current practice. Several laboratory scale experiments were carried out to dry water laden of the sponge media in the SFBD. Three bed loadings of 1.7, 2.0 and 2.3 kg were used at drying temperatures of 80°C, 90°C and 100°C. The experimental works revealed the excellent potential of the SFBD in drying the sponge media rapidly. The behaviour of moisture ratio and drying rate against time were discussed.
