SYSTEM FOR PURIFYING A LIQUID

The invention relates to liquid purification systems with purified water mineralization, which uses predominantly water from various resources.The main problem of existing liquid purification systems, particularly membrane systems, is that during the purification process not only dangerous debris (residual oil, pesticides, herbicides, heavy metals, bacteria, viruses, mechanical particles and other) are removed, but even the minerals necessary for human (calcium, potassium, magnesium, sodium and other), so a mineralization step is needed after the purification step to normalize mineral composition. In the state of the art, there are known liquid purification systems with integral mineralization means and also devices for mineralization which can be connected to liquid purification systems. The working principle of the systems known in the state of the art is that purified liquid flows through a vessel with mineralization additive, which is partly dissolved and the liquid becomes mineralized. The main drawback of the systems known in the state of the art is that due to peculiarities of the dissolving process and/or mineralization additive content, it is impossible to control the mineralization process, so the mineralization level is minor, and the pH is higher than the permitted value.The liquid purification system contains a raw liquid line, a liquid purification unit, a mineralization unit, a purified liquid line is characterized in that mineralization of liquid is performed by controlled dispensing of a mineralization solution obtained by selective purification of raw or drainage liquids, or a mixture thereof.
