The paper presents the results obtained at laboratory, pilot and demonstrative scale with granular activated carbon adsorption as a mean to obtain effluent suitable as water supply for textile finishing industries, that require very stringent limits in terms of COD and colour removal. Laboratory scale tests evidenced that the specific carbon adsorption capacity, both for COD and colour, is highest for a sand-filtered + clariflocculated effluent and lowest for the sand-filtered + ozonated secondary effluent. Pilot and demonstrative scale tests were performed on three filters (0.3, 0.3 and 20 m3 of GAC each) fed with the full scale ozonated secondary effluent.

Flocculation Process

This work compares two pre-treatments (coagulation-flocculation process (CF) and the Fenton oxidation Method (FE)) of the activated carbon adsorption process (AC) to optimize the removal of the organic compounds in landfill leachates. The content of organic compounds was measured in terms of three global parameters: colour, chemical oxygen demand (COD) and dissolved organic carbon (DOC). The result obtained in discontinuous reactor conditions showed an increase in colour removal from 1.5 to 2.0 times and a decrease of COD between 0.3 to 0.5 times for the FE-AC treatment, in relation to the CF-AC treatment. On the other hand, the data obtained in continuous reactor conditions (packed columns) showed that the column fed with leachate CF exhibited operation times 1.3 times longer and a better physiochemical quality in the filtrate (COD and colour) than the one fed with the FE leachate. Nevertheless, the adsorption capacities in the colour removal column of COD and DOC were higher for the FE leachate.

Microwave Desorption

The desulfurization of low-concentration sulfur dioxide in laboratory simulated flue gas and on-site metallurgical flue gas was carried out by activated carbon adsorption in combination with microwave desorption. In comparison with the results of desulfurization, the effect of gas impurities in on-site metallurgical flue gas on the performance of activated carbon adsorption and microwave desorption, as well as the consumption of activated carbon during the desorption process, was also studied. The results show that the gas impurities decrease the unit adsorption capacity by 28.73mg/g and increase the consumption of activated carbon by 0.25g, thus go against the adsorption of activated carbon. Moreover, the use of on-site flue gas as microwave carrier gas in the desorption process can benefit the accumulation of medium-or high-concentration SO2 from the desorption process which can be used to produce acids.

Filtration Technology

Kitchen Vehicle is an indispensable equipment to guarantee the food in battlefield, which played an important role in series of activities include military exercise, flood-fighting rescue and earthquake relief. Water is a necessity in processing staple and non-staple food in field operations, so there is an urgent need to have one safety water supply device with smaller volume and lighter weight to meet the demands of field kitchen work, therefore, a small vehicular water purifier based on the membrane filtration technology plus activated carbon adsorption and ultraviolet light disinfection technology is developed.

Active Substances

This study aimed to determine the best adsorption capacity, compounds contained in activated carbon and burn off that produced. In this study, activated carbon have been prepared from the bark of Salacca zalacca by physically activating using a microwave. The 70 gram  bark of Salacca zalaccawas pyrolised in a furnace with flowing gas N2 with temperature 500 oC for 120 minutes followed by microwave activation at 2450 MHz with power 600 W, 800 W and 1000 W for 20 minutes, 40 minutes and 60 minutes. The results showed the best burn off on microwave power 1000 W with 60 minutes activation time of 90,25%. The best activated carbon adsorption capacity at 800 W microwave power for 20 minutes is 19,96 mg/g. The best allowanced percentage at 800 W microwave power with 20 minutes activation time is 99,82%. Characterization of Fourier Transform Infra-Red (FITR) showed the presence of C=O (carbonyl) bonds indicating the presence of carbon-active substances. After pyrolysis forms a C≡C (Alkuna) bond which indicated more carbon was produced. This is supported by the characterization of Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray Spectroscopy (EDS) showing the surface morphology of rough and irregular activated carbon and the amount of carbon and oxide content on activated carbon of 44,44% and 28,54% sequentially.

This paper studied the activated charcoal absorption EE2 characters by static absorption method. The result showed that EE2 can be removed effectively by activated carbon adsorption. Langmuir isothermal equation can describe the adsorption EE2 characters of activated charcoal well. The relativity adsorption coefficient reached marked or extremely marked level; compared with adsorption performances of different kinds of activated carbon coefficient, the adsorption capacity of PAC3# was the largest to EE2, The adsorption rate of PAC7# was the fastest, but the adsorption capacity of PAC7# was the smaller.
