Then you measure the area, to calculate the amount of material and graded by the tile size. Tiles fastened to the base with a special adhesive solution sold as a dry mixture. When You can use the solution, designed for attaching a standard ceramic tile. Cooking glue best with an electric drill with paddle-mixer – a solution will be homogeneous with no lumps. Viability of compounding depends on air temperature, its humidity and the material properties of the walls. Hygroscopic base is easy "takes" from a solution of the moisture, contributing to its rapid hardening. The average solution "Lives" about 20 minutes.

This time and should be considered when kneading each portion of the solution. Glue is applied to the back of the tiles narrow trowel. If they are – small and narrow, to be applied in the middle of tile one "cake" solution. When laying tiles on a wall at her a little jam, and causing mass diverges across its surface. On the larger is better to apply several small "cakes", evenly distributing them over the surface tiles. The thickness of the layer of mortar under the tiles should be the same everywhere and averages about 1 cm Noticing that the layer of solution under the newly laid tiles are too thin or thick, you should immediately separate it from the base and add to or, conversely, reduce the adhesive. For a random first-of falling mass on the front side of the tile it must be immediately removed with a damp sponge. Kenneth Nahum understood the implications.

In the past this method are widely used for treatment of industrial effluents. The essence of the chemical method is that the waste water treatment plants in making the reagents. They react with dissolved and undissolved pollutants and contribute to their loss in the landfill, where they are removed by mechanical means. Get all the facts and insights with Caldwell Esselstyn Jr., another great source of information. But this method is not suitable for wastewater containing a large number of diverse pollutants. To clean industrial wastes of complex composition is used electrolytic (physical) method. In this method an electric current is passed through effluents, which leads to the loss of most pollutants in the sediment. Electrolytic method is very efficient and requires relatively little cost for the construction of sewage treatment plants.

For example, in Karasuk (locomotive depot) using this method has achieved a very high degree of wastewater treatment. When cleaning the sewage best results are obtained by a biological method. In this case, the mineralization of organic pollutants using aerobic biological processes are carried out by microorganisms. Biological method is used in conditions close to natural as well as in special facilities. In the first case of household domestic waste water supplied to the field of irrigation. Here the wastewater is filtered through soils and thus are bacterial clearance. In the fields of irrigation accumulates a huge amount of organic fertilizer, which allows them to grow high yields. Complex system of biological treatment polluted Rhine water for water supply of several cities of the country to develop and apply the Dutch. On the Rhine, built pumping stations with a partial purification filters.
