De Nora成为全球第15家获得USCG压载水系统型式认可

2019船用洗涤器和压载水系统上海论坛将召开// 洗涤器和压载水2019国际论坛日程公布 //以绿色航运为主题中国造船厂地图将发布// 航运展望论坛2019上IMO新条例的影响

意大利压载水系统供应商De Nora的BALPURE压载水处理系统(BWTS)近日获得了美国海岸警卫队(USCG)的型式认可。该批准适用于国际贸易船舶的安全区域和危险区域安装,包括挂美国国旗船舶。

正在与上海海事大学商船学院一起积极筹备2019船用洗涤器和压载水系统上海论坛将召开的国际船舶海工网说,这是自USCG接受全球压载水处理系统厂家申请认证以来而通过第15家厂家。中国的青岛双瑞和青岛海德威,2家压载水处理系统厂家也是目前获得美国海岸警卫队(USCG)型式认可的15家中的2家,更多的中国厂家也将很快获得美国海岸警卫队(USCG)的型式认可。

以绿色船舶设备研制和服务的不少不少国内外厂家已报名投放国际船舶海工网将于2019年1月15日发布的以绿色航运为主题中国造船厂地图的广告和将参加2019年1月16日-17日的2019船用洗涤器和压载水系统上海论坛

De Nora是通过滑流法对压载水进行电氯化消毒的专利持有人,据此,只有0.5%至1%的海水流进入压载水管需要引入电化学装置。处理水所需的次氯酸盐的必要量在滑流中产生,然后混合到全部压载水中。

该公司认为,对于拥有大型压载舱和大流量水流率的船舶,尤其是大型油轮,散货船和液化天然气运输船,这是一种有效的解决方案,因为它消除了在船上储存次氯酸盐的需要。

“滑流的方法的组合,采用新颖的专利相反极性电极的和可变的杀生物剂的给药提供适合于新的构建和改造项目成本有效而灵活的BWTS,”公司说。

Italian supplier of electrochlorination equipment De Nora has received type-approval from the United States Coastguard (USCG) for its BALPURE ballast water treatment system (BWTS).

The approval is valid for both safe area and hazardous zone installations for internationally trading vessels, including US-flagged ships. It is the 15th system to be certified by the USCG since inception.

De Nora is the  patent holder of electrochlorination disinfection of ballast water through the slipstream method, according to which only a 0.5% to 1% of the seawater flow entering the ballast line needs to be channelled into the electrochemical unit. The necessary amount of hypochlorite required to treat the water is generated in the slipstream and is then mixed to the full volume of ballast water.

The company believes that this is an effective solution for ships with large ballast tanks and high pumping rates, particularly large tankers, bulkers and LNG carriers, as it eliminated the need to store hypochlorite onboard.

“The combination of the slipstream approach, the use of novel patented reverse polarity electrodes and the variable biocide dosing provide a cost effective yet flexible BWTS suitable for both new build and retrofit projects,” the company said.
