This is because the absorption of the silicon-based zeolite filter material to ammonia nitrogen tends to saturation and part of ammonia nitrogen which has been absorbed released from silicon-based zeolite filter material.
It can be seen by scanning electronic microscope that the filter material in the anoxic column covered by biological membrane appears black and the filter material in the aerobic column appears yellowish-brown.
(3) After the start-up finished，each column both the surface and interior of media are completely covered with a thick transparent layer of biofilm rich in species, which plays an important role in the degradation of pollutants. 5 ACKNOWLEDGEMENTS This work was funded by the National Scientific Foundation China (NSFC51178207), Shandong Provincial National Science Foundation (ZR2011EEM003), the Natural Science Foundation of Shandong Province (ZR2012EEL21).

Composite wicks are made of two or more materials or its layer configurations.
The familiar wick materials are copper, stainless steel etc which poses the capillary driving force.
The type of nano materials used to enhance the thermal conductivity is the ability of material to transfer heat which depends on its volume added with base fluid.
The temperature reduction at the evaporator was essential and is obtained with various temperature rise depends on the Nano materials used.

An Experimental Investigation on Transpiration Cooling for Supersonic Vehicle Nose Cone using Porous Material Lianjin Zhao1, a, Jia Lin1, b, Jianhua Wang1, c Jinlong Peng2, d, Dejun Qu2, e, and Lianzhong Chen2, f 1 University of Science and Technology of China, Hefei, 230027, Anhui, P.R.
In the previous experimental investigations, different gaseous coolant [1-4], liquid alcohol and water [5-10]was used as transpiration cooling media, and different porous materials, such as C/C, porous ceramic (91% Al2O3 and 9%SiO2) and metal net structure, were used as transpiration cooling matrixes.
These investigations concluded that the cooling effect of gaseous coolant is limited, but liquid coolant has a large potential to achieve a higher cooling capacity per unit mass due to its large latent heat released by liquid phase change, sintered metal materials have significant advantages in controllable permeability and better machining property.
