Polymer Dissolver-dosing Equipment

There are numerous wastewater treatment technologies that result in the creation of a sludge phase that needs to be separated from the water. This is achieved through a process called flocculation, in which small, difficult-to-handle sludge particles from processes such as chemical treatment or biological steps transform into larger, more manageable flocs suitable for settling or flotation. The chemicals used for this purpose are called polymers, and their aqueous solutions are utilized. Polymers can be in liquid or solid form. To use the solid form, it needs to be dissolved, and the liquid needs to be diluted to achieve the required concentration for dosing, typically around 0.1% to 0.4%. This dissolution process occurs in the polymer dissolver equipment, which can be either two or three compartments. Both types are available in our product range.

Three-Compartment Dissolver

This equipment consists of three sequentially connected compartments, each equipped with a mixer. The first compartment is where the polymer base material is introduced—using a powder feeder for solid forms and a pump for liquids. The amount of polymer to be dosed and the required water quantity are set in the control panel. The solution flows from the first compartment to the second and then to the third, with the mixers continuously in operation. The water introduction is halted in the third reactor by a level switch once the upper level is reached. The mixers continue operating until the preset duration is completed. The prepared polymer solution is extracted from the third compartment using a pump. When the chemical consumption reaches the preset lower level, the level switch signals the automation to restart the process by activating the mixers and water and polymer dosing.

The capacity of the equipment can be adjusted by changing the reactor sizes and the capacity of the chemical dosers.

Two-Compartment Polymer Dissolver

The two-compartment version is generally used for diluting liquid polymer base solutions, as it can prepare the solution more quickly than dissolving solid polymer. The two compartments can be positioned side by side or arranged in a "tower" configuration, with one compartment placed on top of the other. In this setup, the upper reactor is where the polymer is dissolved or diluted, depending on whether it is in powdered or liquid form. The ratio of water and polymer dosing is set in the central control panel, along with the mixing time. After the elapsed time, the automation opens the drain valve, allowing the prepared polymer solution to gravitate into the lower tank. The solution can then be withdrawn for use. After draining, the upper tank begins the solution preparation process again, ensuring a constant supply of polymer solution.
