High Removal Rate

TiO2/active carbon (AC) photo catalysts are prepared by sol-gel method. We have designed a fluidized bed reactor to decontaminate the formaldehyde. In our experiment, active carbon and TiO2/AC are used as the air purification materials in the reactor. Flat aluminum sheets and electric field are introduced into the reactor. Our result shows that TiO2/AC materials have high removal rate, and it can reach 80%. When we add flat sheets and stable electric field, the removal rate reach over 90%.

Powdered Active Carbon

The water samples were fractionated by PES ultrafiltration (UF) membranes with molecular weight cutoffs (MWCOs) of 10kDa□30kDa and PVDF UF membrane with MWCOs of 100kDa, and these permeates were filtrated by PVDF UF membrane with MWCOs of 150kDa and CA microfiltration (MF) membrane with a 0.1μm pore size, as to investigate influence of nature organic matter (NOM) with different MWCOs on flux. The results demonstrated that NOM larger than 30kDa accounting for 15% of total organic matter resulted in 86% of flux decline for MF and 54% for UF, respectively. It was shown that coagulation removed the NOM larger than 100kDa that resulted in over 40% of flux decline. As a result, in spite of removing only 10% of NOM, coagulation enhanced flux substantially. Powdered active carbon (PAC) removed NOM smaller than 30kDa that showed little contribution to flux decline. Therefore, PAC removed 76% of NOM but showed little contribution to enhance flux. It can be concluded that the effect of pretreatment on enhancing flux can not be depended on amounts of NOM removed but on its contribution to flux decline.

A continuous membrane-less anaerobic fluidized bed microbial fuel cell was used to investigate the effects of fluidization parameters on the electro-genesis capacity of the microbial fuel cell. The experimental results indicated that active carbon particles could significantly decrease the start-up time and increase the output voltage of the fluidized bed microbial fuel cell. At steady state operating conditions, the microbial fuel cell output voltages were 700~900 mV and 600~700 mV for with and without the active carbon particles, respectively. The fluidization behavior of the active carbon particles in the microbial fuel cell reactor is one of the key parameters that influences the generation of electricity. The experimental results indicated that to obtain the optimal electric production performance, an appropriate flow velocity should be determined. The fluidized bed microbial fuel cell could be operated in large-scale wastewater treatment processes with high Chemical Oxygen Demand removal efficiencies that reached 93%.
