METHOD TO MONITOR WATER QUALITY AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC G01N33/18 

FIELD: measurement equipment.

SUBSTANCE: group of inventions relates to the field of environmental protection, in particular, to methods and facilities for biomonitoring of water environment. The method includes monitoring of water quality by automatic remote continuous registration in real-time mode of behavioural and/or physiological reactions of water test objects, located in aquaria, through which tested water of stabilised temperature is sent, and monitoring of water quality is carried out by change in condition of test objects, at the same time tested water is automatically redirected via three or more aquaria, with water test objects inside them, at the same time supplied flow of tested water at each moment of time passes only through one aquarium, and in others - water circulation is carried out inside aquaria without external water supply, besides, the period of tested water flow redirection from one aquarium to another is equal to time sufficient to assess behavioural and/or physiological reactions of water test objects, replacement of most water circulating in the aquarium at water flow speed, providing for maintenance of stable environment in it to support water test objects, and tested water quality is monitored by comparison of behavioural and physiological reactions of water test objects between each other at the moment of test water flow passage in aquaria. The system comprises aquaria with water test objects, a unit of water treatment and supply of tested water, drain pipes, a unit of control and registration of behavioural and/or physiological reactions of test objects and an indication unit, at the same time it additionally comprises electrically driven valves according to the number of aquaria, a unit of valve control and a timer, for generation of test intervals, connected with the valve control unit, with a unit of control and registration of behavioural and/or physiological reactions of test objects and an indication unit, and the unit of water treatment and tested water supply via electrically driven valves is connected by means of pipes with aquaria and drain pipes. The method and system increase validity of water monitoring due to development of a system of efficient bioindication, providing for setting correlation between changes of the state of behavioural and/or physiological reactions of water test-objects caused by external factors or directly by tested water quality.

EFFECT: increased validity of monitoring.
