Ozone gas is one of the strongest oxidizing and bleaching agents which leave no residues harmful to the global environment. In recent years, the ozone generator has been widely utilized, However, it has been known that a broader application of ozone is hindered primarily because of its low efficiency of generation. Thus, it is more indispensable to improve actual system efficiency of the silent discharge type ozonizer using high frequency inverter. This paper presents a multi level resonant ozone power regulation by association of high frequency transformers and full bridge invert. And proposed resonant inverter system can generate continuous output voltage. can control linearly quantity of ozone gas. This invert that add PWM forms within square forms of output voltage about one level range. The power regulation characteristics and operating performances of silent discharge (SD)type ozone generating tube load driven by this load proposed inverter using FET modules are illustrated from a practical point of view, which can operate under stable conditions of basic level and PWM hybrid control strategy implemented DSP(2406). The effectoveness of propsed invert type ozonizer is proved by experiment results.

오존을 이용한 마직물의 표백효과를 연구하기 위하여 오존 발생 장치에 의해서 생성된 오존을 물에 용존시킨 오존처리액으로 마직물을 처리하였다. 마직물의 오존처리를 위하여 오존 발생기와 오존 용존조를 사용하였고, 표백 효과를 측정하기 위하여 오존으로 처리된 마직물을 Hunter의 백도, 인장강도, SEM사진을 측정하였다. 발생 오존의 농도는 전압이 높을수록, 원료 산소가스의 유량이 적을수록 증가하였다. 처리포의 표백효과는 오존의 순수 농도가 증가함에 따라 증가하였다. 처리포의 백색도는 처리온도가 $0-15^{\circ}C$, 처리시간이 20분일 때가 최적의 상태를 나타내었다. 처리포의 인장강도는 처리시간이 길수록, 온도를 높여줌에 따라 저하하였다.

An optimization method for a discharge gap, an air cleaner equipment, voltage apply device, pressure and air flow quantity. In our experiments, the high frequency power were applied to the discharge gap with 23-1G(Silent Discharge). The ozone characteristics was measured with air as a supplied gas, which can be used as basic data for the development of small size ozone generator.

With the degradation of water quality and, at the same time increased water usage, the sources of high quality, for examples, river/stream, municipal reservoir, wells, artisan and surface water, are diminishing. Therefore, the importance of water quality has been emphasized over the years through publications and various literature sources. Even though considerable research has resulted in significant strides for providing interpretive information and mitigation strategies for improvement of waters, the quality of which is still questionable. This study aims to propose a completely independent self-contained system for purifying waters, solar-powered ozone generator. It is a semi-permanent and cost effective environmental solution. Functions of ozone treatment are: 1) to maintain oxidative flexibility, 2) remove harmful chemicals, wastes, and other substances, and 3) prevent epizootic microbial outbreaks. Recent advances in technology have allowed the development of the practical, self-contained and independent solar powered device. Solar electrical producing panels that charge batteries are the key to using these systems anywhere electrical power is not available. This paper invites the readers to examine the problem and consider the viable, proven solution the solar powered ozone purifying system. This paper also introduces basic concept and background of solar powered ozone generators and examine its feasibility for improving water quality in rivers and streams.

In order to study the bleaching of cotton fabrics, ozone which has been produced by an ozone generator, has been contacted with cotton fabrics in water at various conditions. The equipments used for the ozone treatment of cotton fabrics were the ozone generator and a liquor/ozone contactor. For the examination of the ozone bleaching effect on cotton fabrics the whiteness, tensile strength, wettability and clark softness of the ozone treated cotton fabrics were measured. The conclusion obtained were, ozone concentration was increased, as the voltage was increased and flow rate was decreased and oxygen amount was increased. Bleaching effect of treated fabrics increased with increasing attributed more the net concentration of ozone rather than the total ozone amount of produced. The whiteness of treated fabrics was found to be best when treating temperature was 15~20<$^{\circ}C$, in acidic condition. The tensile strength of treated fabrics decreased as the treating time increased, and as the temperature raised, and the acidity increased. The wicking distance of treated fabrics increased slightly with increasing the treating time and the temperature. Clark softness of treated fabrics was not changed until passing 30min. of the treating time, then it decreasing linealy with increasing the treating time.

There are many studies and products using a test paper impregnated with chemical solution can react with ozone. The color of a test paper can indicate the concentration of ozone. The purpose of this research is to design and manufacture a system using ultraviolet light source to measure the ozone density. This new technique is based on the characteristic of decomposition from ozone into oxygen under ultraviolet light. We used two sources of ultraviolet light including UV lamp and UVLED to determine the decomposition of ozone. This system is built with the electronic components, sensors and sealed pump tube to measure the ozone density in units of $g/cm^3$,ppm,ppb. In this paper,, we present some initial results of measuring the ozone density from ozone generator after completing inspection for safety.

본 연구는 생활주변에서 오존수를 쉽게 활용할 수 있도록 오존수 발생장치의 활용성을 증가시키고 한 동작으로 작동하는 시스템을 개발하고자 한다. 더 나아가 올리브 오일과 오존과 반응시켜 제조하는 기술에 적용하고자 한다. 기존의 경우 대부분이 오존수 시스템이 아닌 오존발생기 위주의 제품이 많다. 오존수기의 경우 펌프로 강제 흡입시키는 일반압력 방식으로 오존가스 누출 위험요소가 내포 되어 있으나, 본 과제의 경우 인젝터를 이용하여 물의 유입여부에 따른 오존의 발생과 흡입을 제한하고 있어 기존 제품의 오존 누출에 의한 위험을 최소화하였다. 인젝터 방식의 단점에도 불구하고 미생물 살균능을 유지하는 것으로 본 연구에서 사용된 인젝터 방식 오존수 제조 장치의 효용성을 알 수 있었다.

Two types of ozone monitors using UV absorption method were tried in consideration of cost of the monitor and precision in measuring. The high concentration ozone monitor for high concentration real time ozone monitoring from ozone generator was composed of a low pressure mercury lamp as UV source, a photo multiplier tube as UV detector and signal processing unit for the most part. This structure could be very useful for low price high concentration ozone monitor due to simple system structure and fairly good monitoring characteristics. The developed system showed good linear output characteristics to ozone in the measuring concentration range of 0.05 and 2 wt.%. For accuracy ambient ozone monitoring in ambient in ppm level, the system composed of a high power pulsed xenon lamp as UV source, an optical spectrometer with a high sensitivity linear CCD array as UV detector and signal processing unit in brief speaking was proposed our study for the first time in the world. The developed system showed good linearity and sensitivity in relative low measuring range between 10ppm and 10,000ppm, and showed some feasibility of high resolution ozone monitor using CCD array as photodetector.

무성방전형 오존발생장치에서 고농도의 오존을 발생시키기 위해서는 방전공간의 온도를 낮게 유지시켜주는 것이 중요하다. 이때, 방전공간에서 발생된 열을 외부로 전달하기 위한 유전체장벽과 전극간의 접착물질과 접착방법은 전기적, 열적 관점에서 볼 때 방전에 큰 영향을 미치게 된다. 따라서 접착물질과 접착방법은 오존발생에 중요한 변수가 될 수 있다. 본 연구는 접착물질과 방법이 오존발생에 미치는 영향을 조사한 실험적인 결과이다. 접착물질의 종류로는 방열재료로 사용되는 실리콘 화합물질, 전기적인 도전성을 가지는 수지를 사용하였으며 이들의 물성변화를 위해 첨가물질로 차콜(charcoal)을 사용하였다. 결과적으로 접착물질(실리콘 화합물)이 사용되었을 때가 사용하지 않았을 때보다 같은 전압에서 많은 오존발생량을 보여주었다. 또한 접착물질이 사용되었을 때는 순수한 실리콘 화합물이 사용된 경우가 도전성을 가지는 접착물질이 사용되었을 때보다 많은 오존발생량을 보여주었다.
