Filtration Process

The natural rise-husk charcoal was made by burned in a furnace at 230 °C. Carboxylic group (-COOH) was functionalized onto the charcoal by using oxalic acid in situ process. Fourier Transform Infrared Spectroscopy (FTIR) and morphology by Scanning Electron Microscope (SEM) demonstrated that the COOH-group was successfully functionalized on the charcoal and the particles were porous. The COOH-activated charcoal was applied for liming effluent treatment through a filtration media. Eight environmental load parameters was determined by the standard method. The results were compared with the standard permissible limits set by Inland Surface Water-Bangladesh Standards (ISW–BDS-ECR, 1997). It has been observed that the rice husk based activated carbons dramatically reduce the pollutants to permissible level. The removal efficiency of pH, Electrical Conductivity (EC), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Biological Oxygen Demand in 5 days at 20 °C (BOD5), Chemical Oxygen demand (COD), Total Alkalinity, S2- from liming effluent up to 40.0%, 85.89%, 98.8%, 81.32%, 96.74%, 78.6%, 97.15% and 79.61% respectively. In conclusion, the liming effluent simply recycled by filtration process and can be used for industrial purpose.

Zeolite L

Rice husk has a high silica content, so it can be utilized as silica source for zeolite synthesis. In this research, synthesis of zeolite L has been done using silica from rice husk ash without organic template. The synthesized zeolite L is then used as an adsorbent to adsorb methylene blue dye. The steps of zeolite L synthesis include: silica extraction from rice husk ash using NaOH and zeolite L synthesis using hydrothermal method with molar ratio 10 SiO2: Al2O3: 4 K2O: 100 H2O at 170°C for 24 hours. The resulting Zeolite L was then characterized by XRD and SEM. The absorption capacity of methylene blue solution by zeolite L was observed experimentally through the effect of pH of the solution, contact time, and initial concentration of the solution, then determining the isotherm and its absorption kinetics. From XRD and SEM results of zeolite L sample, it is shown that zeolite L has been formed and its particle morphology is a hollow cylinder with cylinder diameter of 0.049 - 0.123 μm. The adsorption process refers to the Freundlich isotherm model which provides the highest correlation coefficient. The methylene blue adsorption process by zeolite L follows pseudo second-order kinetics.

The possible utilization of rice husk activated carbon as an adsorbent for the removal of methylene blue dye from aqueous solutions has been investigated. In this study, activated carbons, prepared from low-cost rice husk by sulfuric acid and zinc chloride activation, were used as the adsorbent for the removal of methylene blue, a basic dye, from aqueous solutions. Effects of various experimental parameters, such as adsorbent dosage and particle size, initial dye concentration, pH and flow rate were investigated in column process. The maximum uptakes of methylene blue by activated rice husk carbon at optimized conditions (particle sizes: 140 ?m; Flow rate: 1.4 mL/min; pH: 10.0; initial volume of methylene blue: 50 mL and initial concentration of methylene blue: 4.0 mg/L etc.) were found to 97.15%. The results indicate that activated carbon of rice husk could be employed as low-cost alternatives to commercial activated carbon in waste water treatment for the removal of basic dyes. This low cost and effective removal method may provide a promising solution for the removal of crystal violet dye from wastewater.DOI: http://dx.doi.org/10.3329/dujs.v60i2.11491 Dhaka Univ. J.
