LIFE SUPPORT SYSTEM OF MAIN OCEANARIUM TANK Russian patent published in 2009 - IPC A01K63/00 A01K63/04 

FIELD: motors and pumps; physics.

SUBSTANCE: system includes water preparation system, sea water preparation system equipped with pumping equipment and switched to the main tank, combined mechanical and biological water treatment system connected to the main tank, mainly through the distribution header and/or balanced chamber to enable water recirculation or adding with no less than one main filter. System also includes contacting tower with water ozonizing unit and degassing chamber, water sterilization system containing no less than one protein skimmer and protein cleaning system. Sewage system, pH and redox-potential measuring and control systems are connected so that they can control, at least, sheared sterilisation of water depending on the required adjustment of redox-potential in the tank. The major part of the aforesaid systems are connected to the tank, mainly, to separate recirculation flows so that to generate three loop-shaped branches with different throughput capacity. The system contains no less than one above mentioned main filter of the combined mechanical and biological treatment. In addition, there is no less than one above mentioned flotation branch with no less than one above mentioned protein skimmer and water sterilisation branch containing no less than one water onozining unit in the system. The main and most loaded branch including no less than one above mentioned main filter is intended for water passing under mechanical and biological treatment conditions in the amounts more than half of the total recirculation flow. Besides, water sterilisation branch includes ozone plant containing ozone generator connected with the aforesaid contacting tower and ozone decomposer and the above degassing chamber, which is connected with main tank at clean water outlet.

EFFECT: improved operational characteristics of main tank life support system.
