Description

The invention relates to the purification of water to obtain desalinated water used for the preparation of solutions covering television screens, and can be used in electronic industry.

The purpose of the invention is to increase the efficiency of use of the filter,

FIG. 1 shows a filter, a longitudinal section; in fig. 2 - water flow through the filter

The filter contains a polyethylene perforated balloon 1, alternating layers of capro-HOBOi; o sieve 2, which acts as a filtering material, are located in it. Silver plated glass plates were used as a bactericidal agent.

3, which are laid in bulk between the layers of the nylon sieve. These plates are made of defective Dewar vessels, their size is preferably chosen in the range of 1-20 mm.

The size of the plates less than I mm requires special: mechanical processing of defective Dewar's vessels, and more than 20 mm - additional time for careful certain laying; plates by layers, which will complicate the process of making the filter

In a sterilized polyethylene cylinder I with a capacity of 3-5 liters, holes are drilled over the entire surface.

4. From the inside, the container is applied with two layers of nylon sieve 2 so as to completely cover its entire inner surface. Then, in Ba1:; Lon sprinkle silver-plated glass plates 3 - fragments of Dyuar vessels, cover with a layer of nylon sieve 2, forming a filtering layer. The plates are selected according to size visually.

The operation is repeated until the polyethylene bottle is filled, with the expectation that the nylon sieve completely covers the silver-plated plates and prevents the silver layers from moving. The cylinder cover is tightly closed. The filters made in this way are placed on the bottom of the demineralized water collector 5 around the water outlet. Polyethylene cylinders, nylon sieve and silver plated

The glass plates are preliminarily contaminated by treatment with ethyl alcohol.

The filter works as follows.

After passing through the ion-exchange purification system, desalted water enters water collectors 5, passes through polyethylene cylinders 1 placed on the bottom of the collector, through the layers of nylon sieve 2 located inside it and silver-plated glass plates 3 and comes out purified from microorganisms and residues of ion-exchange resins, ready for consuming

The number of filters is determined by the working capacity of the collector and amounts to 2-3 filters per 10 m of water. The filter life without cleaning the I collection. The proposed filter has the following advantages: the process of making the filter is simplified, the process of cleaning desalinated water is cheaper because the bactericidal agent is silver-plated glass plates,

made of defective Dewar vessels by simple crushing. At the same time, the silver consumption does not exceed 20 g per 0 m of water; the filter does not affect the

pH of water, its salt composition, which allows its use in a thin technological process of applying cathode-phosphor screens with specified brightness properties
