FIELD: ecology in liquid reservoirs such as aquariums or small-sized basins. ^ SUBSTANCE: method involves utilizing filtering reservoir with apertures in its bottom part; closing apertures with filter made in the form of porous partition or porous massif; fixing main pipeline on or in filtering reservoir for directing therethrough of liquid to be bubbled with air which is supplied from compressor through air duct; bending main pipeline above filter so that liquid is delivered into porous partition or porous massif; passing air duct with curved bent sharpened pipe held by means of adapter through main pipeline wall; connecting air duct end to compressor for feeding air directly into main pipeline; providing intersection of main pipeline wall with curved sharpened pipe, which is bent for feeding of directed air flow through column of liquid forced out from end of main pipeline; drawing by means of high-speed liquid flow of bottom sedimentation such as biological contaminants whose particles solved in liquid are raised under the action of pressure created by air bubbles passing though main pipeline to said end. Bubbling of liquid column with air bubbles results in cavitation of drawn portion of liquid and defining of permanent area of energetic cooperation of filtered volume of fed liquid in bottom part of reservoir at length L. Movement of fishes and other live organisms within aquarium urges biological contaminants to be moved to cleaning zone and transferred to filter. Feeding of bubbled liquid through main pipeline results in solving of oxygen within liquid volume to be filtered, said liquid being supplied at drop feeding velocity for settling in porous partition or porous massif. Porous partition or porous massif is replaced or cleaned as it is contaminated, and laid above apertures of aquarium filtration reservoir, with natural sand and gravel being laid onto aquarium bottom. ^ EFFECT: improved biochemical efficiency in cleaning of aquarium or basin from biological contaminants. ^ 1 dwg |
