Controlling organic carbon levels in municipal water has been hypothesized to limit downstream growth of bacteria and opportunistic pathogens in premise plumbing (OPPPs). Here, the relationships between influent organic carbon (0-15,000 µg ozonated fulvic acid /L) and the number of total bacteria [16S rRNA genes and heterotrophic plate counts (HPCs)] and a wide range of OPPPs (gene copy numbers...
BACKGROUND The treatment options for oral lichen planus (OLP) are numerous and include topical and systemic agents. Intralesional and systemic corticosteroids are used; however, the therapeutic results are often disappointing. OBJECTIVE To compare the influence of ozone, laser, and topical corticosteroid therapies in the treatment of OLP. METHODS One hundred twenty adult patients with ≤3 cm...
in this research effectiveness of immersing three types of contaminated pistachios fresh with hull (exocarp or epicarp), dried in shell and dried with hull from ohady cultivar in ozonated water 0 ppm (control), 4 and 8 ppm ozone concentrations in aqueous solution for range of exposure times 0(control), 2, 4, 6, 8, 10 and12 hours, to decrease of aflatoxin (b1, b2, g1, g2 and total) were investig...
We linked an outbreak of cryptosporidiosis to ozonated apple cider by using molecular and epidemiologic methods. Because ozonation was insufficient in preventing this outbreak, its use in rendering apple cider safe for drinking is questioned.
Effect of Ozonated Water Soaking on Adventitious Root Formation of Willow (Salix koreensis) Cuttings
본 연구는 버드나무의 생물학적 녹화 공법시 삽수 발근의 효율을 높이기 위해 오존수 농도 및 처리시간을 구명하기 수행되었다. 오존발생기를 사용하여 1, 5, 10, 15, 20ppm에서 5분, 2시간 침지처리를 하여 주차별 지상부의 변화를 관찰하고 부정근 개수와 길이를 측정하였다. 그 결과, 20ppm의 오존수를 처리와 1ppm의 5분 동안 처리하면 지상부에 영향을 미쳐 잎이 고사하고, 발근이 이루어지지 않은 현상을 볼 수 있었다. 따라서 부정근의 외관, 개수, 길이 등을 고려해 때, 버드나무 삽수에서 발근과 측지 발생이 이루어진 조건은 따라 5분은 10－15ppm, 2시간은 5ppm을 처리하는 것이 적합하다고 사료된다.
Inactivation kinetics of poliovirus type 1 in ozone demand-free water was investigated by utilizing a fast-flow mixing apparatus. Ozonated water and a solution of ozone demand-free water containing a known quantity of poliovirus type 1 were introduced simultaneously into a mixing chamber, both at a constant rate. This mixture was then passed through a narrow tube of known length and diameter in...
Water treatment plants faced with toxic cyanobacteria have to be able to remove cyanotoxins from raw water. In this study we investigated the efficacy of ozonation coupled with various filtration steps under different cyanobacterial bloom conditions. Cyanobacteria were ozonated in a laboratory-scale batch reactor modeled on a system used by a modern waterworks, with subsequent activated carbon ...
Although orthodox medicine has provided a variety of topical anti-infective agents, some of them have become scarcely effective owing to antibiotic- and chemotherapeutic-resistant pathogens. For more than a century, ozone has been known to be an excellent disinfectant that nevertheless had to be used with caution for its oxidizing properties. Only during the last decade it has been learned how ...
