SEAQUARIUM OPERATION TECHNIQUE Russian patent published in 2009 - IPC A01K63/00 A01K63/04 

FIELD: agriculture.

SUBSTANCE: method proposed envisages deployment of water treatment systems equipped with pumping installations, predominantly multicomponent life-support systems connected to an array of tanks, consisting of at least one main tank and a number of variable volume auxiliary ones and designed primarily for freshwater and marine hydrobionts habitation. The technique provides for definition or correction of the seaquarium display stock species composition consisting primarily of freshwater and marine hydrobionts, modelling biotopes and biocenoses by grouping samples of species mutually compatible in terms of life habits and environmental conditions of habitat and arranging topical displays that may consist of a single or multiple display(s). One does the water treatment required; if arranging for habitation of marine life-forms one shall use natural sea water or (at least) salinised freshwater simulating chemical composition of the latter. One fills the tanks with fresh or sea (salinised) water and actuates the life-support systems. One actuates the systems of water recirculation, mechanical, biological, chemical and protein purification, sterilisation and redox potential and temperature regulation; after that one populates the aquarium tanks with hydrobionts and supervises their operation maintaining the water conditions reliably fit for the hydrobionts vital activities, the array of measures required to provide for that including water recirculation treatment and regulary water replenishment. The flow of water from the main tank channeled into the life support system for purification is split into at least three spouts unequal in terms of discharge intensity which results in formation of at least three loop-type recirculation branches each of them actuating specific life support system components to provide for the relevant type water treatment. Within the circuit of the branch characterised by the greatest discharge intensity (over 50% of the total circulation flow amount as per a specific tank) combined mechanical and biological treatment of water is carried out. One of the two remaining branches is dedicated to equally integrated protein purification and sterilisation process with removal of suspended protein particles from the water performed by way of floatation with streams of air/ozone mixture bubbles passed upstream counter the water down current. Within the other of the two branches above-mentioned water undergoes sterilisation combined with redox potential correction. Total amount of ozone infused into the above water treatment branches is adjusted depending on the demand for redox potential correction with the water currently poured in the tank.

EFFECT: stabilisation of hydrochemical conditions of the hydrobionts aquatic habitat; enhanced efficiency of the hydrobionts life support.
