Self-contained device for correcting and neutralization of the ph of an acidic water with the aid of substances alkalizing a gradual dissolution and dose-related increase in ph

摘要

The present invention relates to a self-contained device for correcting and neutralization of the ph of an acidic water with the aid of substances alkalizing to gradual dissolution and ph dependent. The correction of the ph of the sour water towards the point of the neutral (ph = 7) is necessary for some uses of the water. The correction means of the ph, presented in the form of a solid, liquid or gaseous require the use of additional equipment for the implementation of treatment (strength ph electrode coupled to a metering pump; the filter medium in the neutralisation tank; the material of the diffusion of the gas). The present invention remedies this constraint by proposing a stand-alone device for supplying the form of solid substances alkalizing to gradual dissolution as a function of the initial ph of the water to be treated, including when the water is in permanent renewal, without the use of specific equipment. The quantity of dissolved substances is proportional to the initial ph of the water to be treated. The dissolution is stopped when the ph reaches the neutral (close to 7). The present invention is composed of a mixture comprising at least 3 of the raw materials alkalizing. One or more other raw materials may be added in a minority proportion. The fields of activity of the invention are, for example, the maintenance of swimming pools, and the basins made ornamental, agriculture, the production and the outlet, the aquariarists, the treatment of the water prior to industrial use, the treatment of industrial effluents.
