Efficiency
The efficiency of the system will depend on the air flow rate, concentration of the VOC ...etc. and many other parameters.
There have been a lot of research about the decomposition of organic compounds by photocatalyst. However, the decay properties of different organic compounds are different. You may download some research papers from this website to study the details.
One way to improve the efficiency is in the suction end; better conduit design can improve the indoor air quality significantly.
There may be other systems, e.g. thermal catalytic oxidizers, that will give higher yield in term of VOC destruction. However, the input energy is much higher than that of our photocatalytic systems and the efficiency of the systems are consider to be low.
We are improving our systems, should you have any comment and suggestions, please feel free to contact us.
