The research team including Jang Chol Min, head of laboratory of Nano Physics Engineering Institute developed the gas-detecting transmitter and application technology of micro-bubble, and are building on its success.
They succeeded in developing the gas-detecting material which is capable of detecting quickly and precisely ammonia, hydrogen sulfide and carbon dioxide in the air and on the basis of this, they also developed the automatic gas-detecting transmitter which is capable of measuring and controlling the gas in the given building in real time by manufacturing the solid-state detector which has higher adaptability to environment, lasts longer and is much cheaper than an electrical and chemical way.
They also introduced the micro-bubble technology into purification of waste water so that they could speed up the disintegration of aerobic microorganism into organic materials, and created the reliable technical guarantee for discharging purified water by establishing the process of purifying waste water bio-chemically which can improve the average characteristic indices of water quality such as biochemical and chemical requirement for oxygen and ratio of removing ammonia nitrogen in comparison with the general porous plant by 10 or 20 % and decrease the consumption of electric power to less than 80 % by means of oxidization of organic polluting material which are impossible to decompose with radical ions generating micro-bubbles.
As a result of introduction in one stock-farm, this technology proved very efficient and economic.
In the future, fruitful will be their continuous research for applying it to various fields including purification of water as well as production of crops and vegetables, aquatic culture, IC cleansing, floriculture and preservation of freshness of fishes.
