In the present study, a novel activated carbon was prepared from low-cost eucalyptus seeds, which was utilised for the effectively removal of toxic zinc from the water/wastewater. The prepared adsorbent was studied by Fourier transform infrared spectroscopy and scanning electron microscopic characterisation studies. Adsorption process was experimentally performed for optimising the influencing factors...
The paper is aim to discuss the dye wastewater treatment by sewage sludge-based adsorbent. The adsorbent derived from sewage sludge , which produced through phosphoric acid-microwave method, and commercial activated carbon (ACC) were tested in the process of the Reactive Light Yellow dye wastewater treatment. The effects of pH value, contact time and the adsorbents' amount on the adsorption efficiency...
Removal of Cu2+, Cd2+, Pb2+ and Zn2+ in wastewater was investigated using steel slag as a treatment material, and then mechanism of removal was discussed according to main crystalline phases in steel slag and Zeta potential of steel slag. The results showed the steel slag was a very suitable multi-functional material for the treatment of wastewater containing Zn2+, Cu2+, Cd2+ and Pb2+. Under treatment...
This paper was about absorption characteristics of the new absorbent NSUL-1, which used for treating oilfield injection water. We studied the materials dosage, the adsorption time, pH values, adsorption temperature and other factors affected on adsorption property of NSUL-1, results showed that: when the material dosage was 4.0 g/L, adsorption time was 8h, the oil removal rate reached up to 92%. The...
The paper investigated the treatment effect of modified rice husk as an adsorbent on wastewater containing Zn(II). Langmuir and Freundlich equations quantified the Zn(II) removal effect of modified rice husk. We analyzed characteristics of adsorption kinetics, the initial pH value, temperature effect on adsorption process, and compared with the regeneration efficiency of adsorbent. The results showed...
In the dissertation, the treatment of chromium containing wastewater using sawdust which is a low-cost biosorbent. The influences of physical and chemical parameters such as pH value, reaction time and temperature and the initial concentration of metallic ion on the adsorption process were investigated by batch adsorption. When the pH value 6, reaction temperature 323 K, dosage of sawdust 6 g/L, the...
The purpose of this work was to investigate the kinetics of the adsorption and biodegradation process in adsorption-biodegradation anaerobic sequencing batch reactor (AB-ASBR). Using the whole milk powder as substrate, the volume loading rate (VLR) of influent was 7.0kgCOD / (m3 · d) at 35°C. In order to maintain the optimal pH value, NaHCO3 was added into the influent. The experiment indicated that...
Research on treatment for chloride of desulphurization wastewater by nano-TiO2 is conducted and based on nano-TiO2 dioxide characteristics of adsorption and photo-catalysis. Some affecting factors on the removal efficiency were also studied, such as different dosage, mixing time, pH value of the solution and light time. The catalysis mechanisms of nano-TiO2 on chloride removal efficiency were discussed...
