It was noted that the other indicators do not require an adjustment, as comply with the requirements of Dsanpin 2.2.4-171-10. The economic and ecological expediency of the list intervention in the salt composition of natural water is shown. It is established, that the coagulation of sulfate aluminum can how to remove excess quantity fluoride ions, and lower the pH of the water. However, artesian water of the firm "EFFECT" contains specific organic substances, stabilizing zol aluminium hydroxide, formed as a result of hydrolysis of aluminium sulfate. Particles zola Al(OH)3 is not deleted even when thin filtration of water, and to coagulate in maintaining water within 12...30 days. This will result in increased turbidity of the water,and then precipitation of flakes aluminium hydroxide. Conducted the test of the technology to reduce the fluoride in the water of the customer by means of its mixing with permeate the reverse osmosis. Held tasting the water and found that the water, which is composed by 2/3 of artesian water and 1/3 of permeate reverse osmosis, processed after mixing the granular filter with гранодиоритной downloading at a speed of филтьтрования 15 m/h is most similar to the natural water organoleptic indicators. Developed recommendations for the modification of the existing at the enterprise the system of water treatment artesian water. The proposed modernization implies the inclusion in the existing system of water treatment of enterprises of the following components: - ejector for the removal of surplus of hydrogen sulphide and enrichment of water by oxygen of air; - slow grainy filter with loading in the form of the Crimean sand to remove little suspended particles; - reverse osmosis installation and device for mixing permeate with untreated artesian switch; - high-speed granular filter with the loading of sand for the improvement of organoleptic properties of mixed water.
