Device having bactericidal properties without external power source

Cavorgen Technologies是一家位于安大略省的公司，专注于水处理低影响、非化学解决方案的科学研究和开发。该公司最近开发了一种可以杀死水中细菌的设备。这个装置的核心是一根铜管，周围包裹着一种公司专有的材料。当被细菌污染的水通过管道循环时，在专有材料与被污染的水不接触的情况下，高比例的细菌被杀死；没有外部电源，没有活动部件。Cavorgen和独立实验室在两年的时间里建造和测试了原型设备。结果反复表明，在细菌起始浓度在1000至4000 cfu/mL之间的水中，总大肠菌群和大肠杆菌的细菌杀灭率超过90%。与圭尔夫大学提出的项目是验证该技术的能力，并将研究扩展到商业应用。

Cavorgen Technologies is an Ontario corporation focused on scientific research into and development of low-impact, non-chemical solutions for water treatment. The company has recently developed a device that kills bacteria in water. The essence of this device is a copper tube that is surrounded by a material proprietary to the company. When water contaminated with bacteria is circulated through the tube, a high proportion of the bacteria are killed without contact between the proprietary material and the contaminated water; there is no external power source and no moving parts. Prototype devices have been constructed and tested over a period of two years by Cavorgen and independent laboratories. The results have repeatedly shown bacterial kill rates in excess of 90% for total coliforms and E. coli specifically, in water where the starting concentration of bacteria is between 1000 and 4000 cfu/mL. The project proposed with the University of Guelph is to verify the technology's capabilities and to extend the research towards commercial application.
