An apparatus for filtering and mineralizing a fluid. The apparatus includes an amount of contaminated fluid located in a reservoir and a cartridge that is located downstream from the reservoir and in fluid communication with it. A filter is in fluid communication with the reservoir and the cartridge. The contaminated fluid is pumped along a pathway from the reservoir to the cartridge so that the contaminated fluid moves through the filter to generate filtered fluid in the cartridge. A pre-determined amount of an additive is associated with the cartridge for adding to the filtered fluid to generate a final fluid with the amount of the additive material.

A control system has a water purification module and a control module. The water purification module has a preliminary filter and a reverse osmosis filter. The control module regularly controls the purification and the drainage of the water purification module, and solves the problem that the TDS value of the water on both sides of the reverse osmosis membrane is too high after the water purifier is on standby for a period of time. The control system regularly drains high concentration water on both sides of the reverse osmosis membrane to improve water purification efficiency.

The booster pump is set in the filtering pipeline. The pure water pipeline is connected between a pure water outlet of the RO filter membrane and one end of the washing pipeline. The joint of the pure water pipeline and the washing pipeline is provided with a high-pressure pump. One end of the waste water pipeline is connected with waste water outlet of the RO filtering membrane, and the other end is a discharge end. The second branch line is connected between the waste water pipeline and the washing pipeline.

A liquid purification system 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 purification process not only dangerous debris (residual oil, pesticides, herbicides, heavy metals, bacteria, viruses, mechanical particles and other) are removed, but even minerals necessary for human (calcium, potassium, magnesium, sodium and other), so mineralization step is needed after purification step to normalize mineral composition. In the state of the art 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 systems, known in the state of the art, is that purified liquid flows through the 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 mineralization process, so the mineralization level is minor, and the pH is higher than the permitted value. Liquid purification system containing raw liquid line, liquid purification unit, mineralization unit, purified liquid line is characterized in that, mineralization of liquid is done by controlled dispensing of mineralization solution, obtained by selective raw or drainage liquids or their mixture.
