SAMPLING METHOD FROM BALLAST CONTAINERS OF VESSELS SHIPS "RIVER-SEA" AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC G01N1/10 B63B13/00 

FIELD: biotechnology.

SUBSTANCE: method comprises taking the water from the containers with their subsequent analysis for the presence of pathogenic bacteria and microorganisms. At that the combined sample is formed of sample containers, for which pumping of ballast water of each selected container is carried separately for 5-10 minutes in a volume of at least 200 liters through the mechanical filters. Vibrio cholerae are deposited on cartridges with pores from 2 microns and larger microorganisms - on cartridges with pores from 10 to 50 microns. Upon completion of selection the cartridges are pulled out and placed in sterile containers, which are delivered for analysis to the laboratory. The sampling procedures are carried out for 2-2.5 hours and the infestation of the vessel is determined based on the combined sample. The device comprises a suction pump with the suction pipe attached to it and is made in the form of a portable structure having bases and a lid with a handle. On the base of the device the evacuation pump and two filters are mounted consecutively, equipped with replaceable cartridges of mechanical cleaning. The pump and filters are interconnected by pipeline, and between the pump and the first filter the water meter is built in to record the pumped ballast water.

EFFECT: increased efficiency of bacteriological studies of ballast water.
