Modification of the Aeration-Supplied Configuration in the Biodrying Process for Refuse-Derived Fuel (RDF) Production

Biodrying is an essential part of the mechanical–biological treatment process that minimizes moisture content and simultaneously maximizes heating value for refuse-derived fuel (RDF) production. Although mechanical separation operates effectively in Thailand’s RDF production, high organic levels their degradation cause contamination RDF, producing wet RDF. Aeration effective biodrying process, can reduce RDF’s as well increase its value. To maximize effect, aeration should be optimized based on waste conditions. This study proposes a modified aeration-supplied configuration biodrying. The rate was period within operation; first from beginning until day 2.5, second 2.5 to 5. optimal supply 0.5 m3/kg/day then 0.3 end process; this yielded greatest decrease 35% increased low biodried product by 11%. final were 24.07% 4787 kcal/kg, respectively. Therefore, could applied meet requirements production standard local cement industry.
