Water filtration parasitology analysis Giardia Criptosporidium

SAMPLER CONCENTRATOR the ProboKonG

 

: : : probokong

 

Function.

The ProboKonG is a transportable filtering device for concentrating large volume (up to 400 - 1000 litres) water suspensions of microbiological objects having sizes more than 1.5 micron (plancton, sanitary significant protozoa, gelmint eggs, etc.) to up to near 100 ml concentrate volume.

The filtering of the samples can be carried out both in the laboratory, and directly on a sampling place:

water supply stantions, water pipes, manufacture of bottled water, springs, wells, water bodies, rivers, seas, swimming pools, etc.(See)

Also, the device is used for washing-off everyday life objects and vegetables for carrying out analysis of parasitical contamination.

Useful distinctions from the analogues.

The filtering is carried out through the precoat bed of filter medium with temporary pores between particles, which is formed from a filtering powder on the filtering element (2) by water flow, rather than through cartrige filter.

Under this technique it's not necessary to perform special operations, such as demolition of the filter, or washing the deposit off the filter for bio-objects extraction, in contrast to cartrige filters.

When the filtration ends, the filter breaks down itself, disengaging the bio-particles from temporary pores for their further analysis and resulting in only 100 ml of the concentrate.

The separation bio-particles from the filter medium occurs automatically in the conventional process of flotation for concentrate cleaning.

The specificity of the technique enables a high output factor (70-90%%) of the bio-particles from the filter.

 

Principle of operation

Under opened tap 4C for water overflow and closed tap 4B tested water is supplied through the inlet 7. A portion of filtering media is placed into the bottle 1 which is attach to the distributing head 3, the tap 4B is opened and the tap 4C is closed to supply water into the device, water passes through the flow-meter 6, comes into the bottle 1 where stirs up filter medium and passing through the filtering element 2 deposits the bed of filter medium on it and through the outlet 8B abandons the device.

Bio-particles are caught in the filter. When the filtration stops, the tap 4C is opened and the tap 4B is closed, the powder filter falls down from the element 2 onto the bottom of bottle 1, the latter is detached from the distributing head 3, is plugged and is transported to a laboratory for analysis.

Separation of bioparticles from filter powder is accomplished by settling or by centrifugation and flotation. Subsequent development may be accomplished by one of common methods -direct microscopy, immunomagnetic separation with immunofluorescent microscopy, PCR and so on..
