Contamination Control in a Portable-Materials With Photochemical Process

Abstract

Contamination control area refers to the control / eliminated of the activities of microorganisms present in the materials or process. This technique to eliminated is major importance in this study are those that cause food spoilage and are infectious. The principal areas of interest in this study are health, aerospace and food industry because the materials utilized in the process charging the contamination; thus, to control these microorganisms, moist heat and chemicals are used. However, technological development has led to a problem with some portable-materials, as these techniques are not suitable in specific cases in which there may be material damage and health safety problems. To address these problems, the present research identified a new constructive experimental device that has a triple deck (UV, Ozone, and UV-Ozone). This configuration can sterilize material with photochemical process cannot be damaged. After this protocol was generated, flat plate materials were contaminated with E. coli and 3 different configuration protocols were applied. The results show a microbial reduction of approximately 99.999% after an exposure of 30 – 40 min with ozone/UV, 30 min with UV-only, and 20 min with ozone. This device has the ability to sterilize the materials.

Orange peel biochar/clay/titania composites: low cost, high performance, and easy-to-reuse photocatalysts for the degradation of tetracycline in water

“…16,70 Contrary to our data, other Environmental Science: Water Research & Technology Paper data suggest that the hybrid clay components do not necessarily contribute to the photoactive nature of the nanocomposites but merely acted as substrates for the development of the nanocomposites. 71,72 The reason for this difference is currently unknown.…”
