Description

The device consists of a storage container with a concentrated disinfectant solution solution that is open and placed inside a larger, lid-closed container, submerged below the lowest level of the water source and connected to it, for example, through openings. An auxiliary dosing tube with a tube, the other end of which extends above the surface of the water source and is provided with a funnel for replenishing a concentrated solution of disinfectant, extends through the lid of the larger container to the bottom of the storage container.

BACKGROUND OF THE INVENTION The present invention relates to a device for the disinfection of drinking water from small water sources using disinfectant technological solutions. <

Drinking water disinfection devices are known which can be placed directly into or in the immediate vicinity of small water sources. Typically, such a device consists of a solution of disinfectant solution provided with a separate dosing device which measures the set amount of the dosing solution. At other times, a small bottle of disinfectant solution is immersed in a small potable water source, which enters disinfected water only by osmotic pressure through a suitable dispersing device. A common disadvantage of these devices is that they either require electrical power to drive the metering pump and to control the metering automatics, or that they add a disinfectant solution to the treated water irregularly and independently of intermittent drinking water from a small water source. A longer disadvantage of the known devices is the low dosing accuracy, which is manifested in the high fluctuation of the disinfectant solution added, especially in the case of intermittent withdrawal of drinking water.

The above-mentioned disadvantages are eliminated by the device according to the invention, consisting of a storage container with a concentrated disinfectant solution solution, which is located inside another larger container with a concurrently diluted solution of this substance, a dispersion nozzle or holes and Auxiliary dispensing tubing extending through the lid of the dilute solution container and extending to the bottom of the concentrated solution container is further directed above the water level in the small water source where a funnel for replenishing disinfectant is inserted into the tubing. In such an arrangement, the disinfectant solution is fed to the dispersion openings and from there to the disinfected water.

The advantage of the device according to the invention is that when drinking water is removed, which results in a change in the water level in the small source, it dispenses into it a solution of diluted disinfectant by volume, so that when the water level in the small water source drops which results in the dispensing of the diluted disinfectant solution into the disinfected water through the dispersion nozzle or openings. At rest, ie at the same drinking water levels in a small water source and in the dosing tube, the disinfectant enters the water only due to osmotic pressure through the dispersion openings. As the water level in the small non-water source increases, osmosis and diffusion balance the disinfectant concentrations inside the vessels interconnected so that virtually the same amount of disinfectant solution is continuously dosed to complete. vydávkování zásobního; ro.zt.Qk.u ,, when. a concentrated disinfectant solution is introduced into the dosing device via a funnel. A further advantage of the device according to the invention is that it is possible in a simple manner to carry out sudden disinfection by slightly over-chlorination in heavily soiled small water sources, which in this way. >cases.;contamination; drinking water; small vodníqh zdrojůjbezpodmmečně required, particularly in the current when there fvšeobecnému * to these sources of pollution of drinking water due to the constantly deteriorating živoi®ÍJip, -PR _O (including the center through the funnel plastic přiléváme intermittently into the reservoir bottle concentrated solution of disinfectant HMPT small Accordingly, the volume of drinking water added via the funnel will displace the initially diluted disinfectant solution from the larger volume container through the dispersing openings into the disinfected water. water through a funnel at long intervals of approx. 7 to 14 days, it is also possible to disinfect drinking water even with minimal consumption, or in all cases where there is an irregular drop in water level in a small water source. ve In the case of large accumulations, where the simple device according to the invention is placed on the inflow of drinking water into the reservoir, at intervals of time add to the dispenser an appropriate volume of water according to the required degree of disinfection and disinfected water flow. water sources under extraordinary circumstances. account, drinking mine. water. substances affecting ... very unfavorable physiological, bacteriological and biological properties of polluted water, their treatment in this case. preferably hydroperoxide followed by filtration of the water so treated. over. granular acre,

Claims (4)

The device consists of a closed container 4 in thermoplastics with a dilute solution of disinfectant, provided with a sealing lid 7. This container 4 has a storage container inside 2 of smaller volume or in smaller devices also a graduated glass cylinder to which a concentrated solution of disinfectant, usually sodium hypochlorite, is added. This is gradually displaced from the storage container 2 into a larger container 4 with the already diluted solution of the mass and from it through the dispersion nozzle in the bottom or through the mere openings 5 in the container lid 7 into disinfected water. The gradual displacement of this dilute solution is effected by pulsating the level of the solution in the tube 6 through a tube 3 leading to the bottom of the storage container 2 with concentrated solution and passing over the lid 7 of the container 4 of a larger volume above the drinking water level to a location in a small water source readily accessible and protected to handle the small funnel 8 inserted into the tube 6. preferably small holes 5, for example a total of 4, which may be provided with rubber stoppers. By releasing these plugs, the amount of solution passing into the disinfected water can be adjusted once and for all for each source according to the desired concentration of the disinfectant, contains the sources and depending on the amount and method of withdrawing the drinking water. The device according to the invention operates in such a way that the water level in the well 1 decreases when drinking water is withdrawn from a small water source. With this drinking water from a small water source the levels in the well 1 and in the hose 6 are gradually equalized. mass from the larger container 4 to the disinfected water through the opening 5 of the dispersion nozzle in the bottom of the larger container 4 or the openings 5 of the container 4. The device operates in the indicated manner automatically whenever drinking water is taken from a small water source. resources. In the case of wells 1 of larger depths and volumes where there is no significant change in water level during sampling, it is possible to carry out disinfection by regularly dripping water through the funnel into the inner cylinder. In the same way, the drinking water is automatically disinfected in the rain when the funnel is positioned so that the falling rain water drips into the funnel. In sources with a continuous withdrawal of drinking water from the spring slots as well as with varying flow, pulsation of the water level and thus the pulsation of the solution in the tubing caused by intermittent withdrawal of water from the collecting device by intermittent siphon can be created. The amount of disinfectant dosing can be controlled by varying the diameter of the dosing tube at the water level in the source or by releasing the number of plugs of the larger container 4 or by mixing a concentrated disinfectant solution. Subject A device for the disinfection of drinking water from small water sources comprising a storage container with a concentrated disinfectant solution solution, characterized in that the storage container (2) is open at its upper part and is located inside a larger, closed container (4), located inside the water source below the lowest level, which is connected to it through the openings (5), whereby through the lid (7) of the closed vessel (4), one end of the auxiliary dosing tube (6) with a tube ( 3), while at its other end a closed vessel (4) above the surface is provided with a funnel (8). 4 sheets of drawings FIG
