Abstract

The present invention relates to a method for processing mineralised water containing sulfates and chlorides and in which the ratio between the chloride and sulfate concentrations does not exceed 1:6. This method comprises different steps such as water preparation, concentration, crystallisation and centrifugation. The crystallisation is carried out at a total salt content of between 50 and 100 g/l, while the concentration is carried out according to a reverse osmosis method under a working pressure of between 1.5 and 4.0 Mpa. During the concentration process, the ratio between the sulfate and chloride concentrations increases at least 2.5 times. Due to the feedback into the processing cycle of the residual solutions obtained from the crystallisation and the centrifugation, it is possible to further increase the ratio between the sulfate and chloride concentrations before the concentration step. When mixing the residual solutions with the starting water, the ratio between said concentrations can be increased by at least 18 %. When mixing the residual solutions with the starting water and with the water after each water preparation step, this same ratio can be increased by at least 3 % in the starting water and by at least 17 % in the water to be concentrated. The preparation step of the present method may for example include the elimination of heavy metals and of calcium- and magnesium-containing solids.

The indicated range of values of the general bodyguard allows you to use the method of concentrating the concentrate for the purpose of concentrating. Whereas this process is applied and the working pressure is from 1.5 to 4.0% and the specified law of affection means that the increase in the rate of sulphide is reduced by at least 2.5, This is explained by the fact that, in the case of working in the case of refrigerant - ions, which occurred in the past, we had much better luck. For mildly disproportionate water with a difference of less than 1: 6 in terms of health and other conditions, there is little evidence of It eliminates the cost of accrual of accruals due to installation due to installation in the process of processing. The indicated reduction of the concentra- tions in the residual output is much higher than in the original water. Otherwise, reduce energy consumption in the cycle, and also further increase the percentage reduction if you return Residual products in the cycle of the processing of the low-speed. In this case, the rest of the products after installation and centrifugal mixing are mixed, and then they are broken into a few transfers.
