Sugarcane Bagasse Ash

Industrial wastewater containing toxic pollutants such as heavy metals tends to contaminate the environment once it is release without proper treatment. Heavy metals are toxic to both human and other living organisms. It is necessary to treat industrial wastewater polluted with heavy metals prior to its discharge into the receiving environment. In this study, low cost adsorbent was generated from sugarcane bagasse through incineration. The prepared adsorbent “microwave incinerated sugarcane bagasse ash” (MISCBA) was used in removing copper and zinc from aqueous solution. Parameters of importance such as pH, contact time and adsorbent dosages are studied to investigate their effects on the adsorption of copper and zinc. Maximum adsorption was observed at pH 6.0, contact time of 180 minutes and adsorbent dosage of 10 g/L. Zinc removal follows Langmuir isotherm model with correlation coefficient of 0.9291. Copper adsorption follows both Langmuir and Freundlich isotherm model with correlation coefficient of 0.9181 and 0.9742, respectively. Removal capacities of 38.4 mg/g and 20.4 mg/g were obtained for copper and zinc, respectively. Application of MISCBA as low - cost adsorbent have shown significant outcome in removal of copper and zinc from aqueous solution.

Bagasse Fly Ash

To enhance the digestion rate of a landfill leachate in the anaerobic packed bed reactor, a natural zeolite and sugarcane bagasse fly ash (BFA) were tested as the immobilization media. In order to scale up this process and systematically optimize the reactor performance, a kinetics model was needed. The suitability of the Contois and Haldane growth kinetic models were tested on the experiment data. It turned out that Contois gave the best fit for both acidogenic and methanogenic steps. A statistical analysis on Contois kinetic parameters using the Pearson correlation coefficient indicated that, in comparison with the BFA, the zeolite, as an immobilization media, showed more positive effects on the performance of the anaerobic digestion of a leachate.
