A hydro-automated installation for water purification comprises a filter base, loaded with floating filtering material, distributing system, pipes for influent water supply and filter drainage, and filter rate controller. The controller is connected with a siphon pipe of flush water by air tube. The descending branch line of flush siphon pipe is sharply declined from the ascending branch line, and made of minor diameter with sharp bend in the upper part and decline. To the lower end of the descending branch line of flush siphon pipe the starting siphon pipe is connected. The invention provides the dramatic increase in amount of vacuum in the flush siphon pipe at launch time, which will lead to the stable start of flush siphon pipe and to the decrease in water consumption for the start of siphon pipe. |
