Patent number: 8986550Abstract: A method and a modular system for performing a sterilizing treatment of ballast waters (12) onboard of a ship (10), for reducing and/or removing the contents of invasive living micro-organisms. A water loading pump (13) and a water preliminary filtering stage (14) are operatively connected to a plurality of ballast water storing tanks (11); a UV sterilizing apparatus (18) for the ballast water is submerged into the ballast water in each water storing tank (11), and is operatively connected to a local control unit (QE). Each UV sterilizing apparatus (18) comprises a UV radiation source (28). The ballast water (12) inside each storing tank (11) is recirculated although the UV radiation source (28), for a required time and mixed with the ballast water inside the water storage tank (11) to enable the living micro-organisms to be substantially reduced or eliminated, during the navigation.Type: GrantFiled: June 18, 2012Date of Patent: March 24, 2015Assignee: Artes Ingegneria S.p.A.Inventors: Pasquale Punzo, Giuseppe Balzano

Publication number: 20150014550Abstract: A ultra-violet liquid processing device comprises a liquid processor, a lamp holder, a latching mechanism provided within the lamp holder, and a lamp holder fixed cover provided with a lock hole therein. The latching mechanism comprises a locking dog able to extend from or retract into the lamp holder and a water nozzle blocker. When the lamp holder is pressed on the liquid processor and connected with the liquid processor by lamp holder fixed cover, the locking dog projects from the lamp holder and enter into the lock hole of the lamp holder fixed cover, so that the lamp holder fixed cover is locked and cannot move. By means of the lamp holder fixed cover being locked by the latching mechanism and not able to be moved, the ultra-violet liquid processing device is sealed reliably by means of the substantial structure.Type: ApplicationFiled: March 9, 2012Publication date: January 15, 2015Applicant: SHENZHEN XINGRISHENG INDUSTRIAL CO., LTD.Inventor: Yonghao Li
