Rice Husk Packed Bed Column Reactor To Remove Cadmium From Landfill Leachate

Abstract

The landfill leachate can be a major problem due to large variability of high organic, inorganic, heavy metal content and toxicity characteristics from landfill leachate such as cadmium. Thus, this study was aimed to observe the application of rice husk packed bed column to reduce cadmium from landfill leachate. Experiment was conducted in gravity down flow system by pumping landfill leachate into packed bed column. The effect of influent flow rate to adsorption capacity was studied by varying flow rate (5 mL/min and 10 mL/min). The effluent-influent concentration ratio C /C (%) as a function of throughput volume (L) was used to represent the e 0 breakthrough curve in column systems. Result shows that the flow rate of 5 mL/min was favorable to achieve higher removal rates with the percentage of cadmium was 57 %. At breakthrough time, the cadmium effluent concentration reached on 0.01 mg/l for both of flow rate.Kata Kunci : Landfill leachate, packed bed column, adsorption, rice husk, cadmium. ABSTRAK

Removal of Zinc onto Several Adsorbents Derived from Waste Activated Sludge of Crumb Rubber Industry (CRI-WAS)

“…Several studies have been made significant contributions in this area. Utilizing a number of adsorbent materials from agricultural waste such as, sawdust and neem bark [8], [9], rice husk [10], Durio zibethinus seed [11], shell and seed of Kelengkeng fruits [12], stem tree of Soybean [13], Jengkol's husk [14], Eleocharis dulcis Fibers [15], Arenga pinnata fruit shell [16], and from industrial sludge such as from from WWTP (waste water treatment plant) sludge [17]- [20], metal industry sludge [21], palm oil mill sludge [22], yarn factory sludge [23], dairy filtering station sludge [24], drinking water treatment sludge [25]- [27], to minimize metal ions was reported.…”
