It is very important that the researcher understand the process of development for industrial equipment. In order to understand the process, I want to show the sample of development case. During development of equipment for groundwater polluted by VOC(Volatile Organic Compound), I could not apply the ultrasound reactor. Because the size and decompose ability of reactor were so small to apply industrial scale. But the ultrasound reactor could decompose VOC safely. So I made process design as follows. First I arranged the system of separation of the VOC dissolved in groundwater to gas phase by means of evaporation and degassing in vacuum state. Second the condensate water polluted VOC was treated by ultrasound reactor and the VOC in gas phase was decompose by heat reaction. The amount of condensate water was very small such as 1% of feed water. The performance of new equipment is excellent. Polluted water of PCE, TCE ,cis-1,2-DCE ,Benzene ,etc could treat approx. 10mg/L to 0.0lmg/L without any chemicals ,new waste ,hazardous byproducts and with energy saved. The researcher has to pay attention to describe in the paper as follows items. 1. Heat and mass balance. 2. The way of scale up. 3. Energy consumption of ultrasound. 4. The impact against environment
