    Abstract: This invention relates to apparatus and methods for the disinfection of fluids and, in particular, to the disinfection of industrial fluids with ultraviolet radiation. These fluids are typically used in manufacturing as coolants in both long and short assembly lines. They commonly accumulate contaminants from multiple and diverse sources including oil and microorganisms. Fluids can be disinfected by establishing a fluid flow rate sufficient to prevent occlusion of the walls of the ultraviolet transmissible portion by contaminants. Fluids may be so heavily contaminated so as to require removal of at least a minimum percentage of contaminants (MPC) prior to irradiation. Such fluids may be processed to remove the minimum percentage of contaminants according to the equation: MPC=102-(23.45.times.lnV). Subject to removal of the MPC, a flow rate can be established to prevent occlusion of ultraviolet-transmissible portions of the flow path and thereby successfully treat the fluid with a disinfecting amount of ultraviolet radiation. Using these methods, microorganism levels can be greatly reduced with a reduced need for biocides or other anti-bacterial or anti-fungal agents. The methods and apparatus of the invention also comprise a flattened-tube mechanism for increased exposure to UV radiation and a turbulence-generating system to increase effectiveness of radiation treatments. Turbulence-generating systems include means for creating pressure differentials or aeration in the fluid stream as well as various types of structures such as ribbons, paddles, cones, beads or vanes that can be placed within the lumen of the tubing system. These methods are highly effective at extending the useful life of fluids such as coolants and reducing or eliminating the risks posed to workers by heavily contaminated or biocide-treated coolants.

    Abstract translation: 本发明涉及用于消毒流体的装置和方法，特别涉及用紫外线辐射消毒工业流体的装置和方法。 这些流体通常用于制造长和短组装线中的冷却剂。 它们通常会积聚多种不同来源的污染物，包括油和微生物。 可以通过建立足以防止紫外线传播部分的壁被污染物堵塞的流体流速来消除流体。 流体可能受到如此严重的污染，以便在照射之前要求除去至少最少百分比的污染物（MPC）。 可以按照以下等式处理这些流体以除去最小百分比的污染物：MPC = 102-（23.45×lnV）。 在去除MPC的情况下，可以建立流量以防止流路的紫外线透射部分的遮挡，从而以消毒量的紫外线辐射成功地处理流体。 使用这些方法，可以大大降低微生物水平，同时减少对杀生物剂或其它抗菌或抗真菌剂的需要。 本发明的方法和装置还包括用于增加暴露于UV辐射的扁平管机构和用于增加辐射治疗效果的湍流产生系统。 湍流产生系统包括用于在流体流中产生压差或曝气的装置以及可以放置在管道系统的内腔内的各种类型的结构，例如带状物，桨叶，锥体，珠粒或叶片。 这些方法在延长流体如冷却剂的使用寿命方面非常有效，并减少或消除了受重污染或杀生物剂处理的冷却剂对工人造成的风险。
