Advanced studies of ballast water treatment with UV radiation

船舶压载水的处理以防止物种引入是由国际海事组织（IMO）和美国海岸警卫队（默认情况下）的法规管理的。紫外线辐射（UV）处理是一种经过验证的废水灭菌技术，由Trojan Technologies（伦敦，安大略）领导。紫外线对杀灭压载水生物是有效的。然而，目前验证处理技术的标准是基于活体染色-一种对生存能力的间接评估-只有在证明有效的情况下才能使用替代测试。这对紫外线的应用至关重要，因为当用目前监管机构用于验证处理技术的活体染色试验进行测试时，大量被紫外线灭活的细胞似乎是活的。在没有更准确的替代测试的情况下，这些误导性的结果将需要昂贵的和不必要的过度治疗时，紫外线用于治疗。这反过来又会阻止特洛伊有效地竞争一个潜在的年度市场份额估计为c。未来6年每年10亿美元。

Treatment of ships' ballast water to prevent species introductions is governed by regulations from the International Maritime Organization (IMO) and, by default, the US Coast Guard. Treatment with ultraviolet radiation (UV) is a proven technology for wastewater sterilization, an application led by Trojan Technologies (London, Ontario). UV is demonstrably effective for killing ballast water organisms. However, the current standard for validating treatment technologies is based on vital stains - an indirect assessment of viability - and alternative tests can be used only if they can be proved to work. This is critical to application of UV, because significant numbers of cells that are inactivated by UV appear to be alive when tested with vital stain assays that are currently being used by regulators to validate treatment technologies. In the absence of more accurate alternative tests, these misleading results would necessitate expensive and unnecessary over-treatment when UV is used for treatment. That in turn would prevent Trojan from competing effectively for a potential annual market share estimated at c. $1 billion annually for the next 6 years.
