Advanced studies of ballast water treatment with UV radiation

船舶压载水的处理以防止物种引入受到国际海事组织(IMO)和美国海岸警卫队(默认情况下)的监管。紫外线辐射(UV)处理是一项经过验证的废水消毒技术，由特洛伊技术公司(安大略省伦敦)领导。紫外线对杀灭压载水生物是明显有效的。然而，目前验证治疗技术的标准是基于生命染色--对生存能力的间接评估--只有在证明它们有效的情况下，才能使用替代测试。这对紫外线的应用至关重要，因为被紫外线灭活的相当数量的细胞在使用重要染色分析进行测试时似乎是活的，目前监管机构正在使用这些分析来验证处理技术。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在使用紫外线进行治疗时进行昂贵和不必要的过度治疗。这反过来又会阻止特洛伊木马在未来6年内有效地争夺潜在的年度市场份额，估计每年约为10亿加元。

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.
