Anaerobic Reactor

An expanded-bed anaerobic reactor with granular activated carbon (GAC) medium has been developed to treat wastewaters that contain a high concentration of inhibitory and/or refractory organic compounds as well as readily degradable organic compounds. The process is characterised by a combination of two removal mechanisms; adsorption on GAC and biological degradation by microorganisms grown on GAC. Applicability of the reactor to treatment of phenol, chloroacetaldehyde (CAA), pentachlorophenol (PCP) and tetrachloroethylene (PCE) was discussed based on experimental data. All chemicals focused on here were removed well and stably at a removal efficiency of more than 98% even during starting operation and shock load operation. Chemicals in influent that exceeded biological degradation capacity was initially adsorbed on GAC and then gradually degraded, and hence the adsorptive capacity of GAC was regenerated biologically. These results proved that a biological activated carbon anaerobic reactor was effective for treatment of wastewater containing hazardous chemicals, especially for strongly absorbable chemicals, as well as readily degradable organic compounds at high concentration.

Dyes Adsorption

In this present study, rubber seed-coated activated carbon (RSCAC) was used as a natural adsorbent to remove basic (MB), acid (MR) and reactive (RBV) dyes using batch process. Each dye in the adsorption process was tested at different initial concentration from 50-500 mg/l. Different dyes showed different percentage removals. The highest removal was recorded by MB which was up to 99.9 %. The experimental data was analyzed with Langmuir and Freundlich adsorption models. The data fitted well with Langmuir. The adsorption capacity were 332.99, 210.33 and 155.37 mg/g for MB, MR and RBV, respectively.

A study of water as the agent of functionalization is still new since most of researchers used acid as the agent of functionalization. The objective of this study is to investigate the used of water as a medium of functionalization of commercialized activated carbon in order to be used in removal of methylene blue dyes from synthetic wastewater via adsorption. The parameters for functionalization of the commercialized activated carbon included temperature at 35°C, contact time of 5 hours and various frequency at 100, 150 and 200 rpm. The experiment was conducted in a batch process where the commercialized activated carbon were functionalized under the mentioned parameters. The functionalized activated carbon were characterized using Fourier Transform Infra-Red (FTIR) Spectroscopy. The FTIR analysis indicated the increase of the amount of functional group attached to the activated carbon. The dye adsorption study was conducted by using methylene blue solution with initial concentration of 500 ppm as adsorbate and the functionalized activated carbon as adsorbent. A standard calibration curve for methylene blue solution was generated using of Ultraviolet-Visible (Uv-Vis) Spectrophotometer. The result from the adsorption study was the parameter of temperature at 35°C, contact time of 5 hours and varying water bath shaker frequency at 100 rpm yield the best adsorption rate.
