POLIFLOC are continuous polymer preparation equipment.
A combination of elemental treatments is required in all water purification processes to eliminate suspended particles, colloids, and dissolved substances. One of the main processes used for the elimination of colloids is decantation or flotation by the adding of synthetic flocculants called polyelectrolytes.
The POLIFLOC® range is a series of compact equipment that enables a homogenous polyelectrolyte solution to be prepared from a solid, liquid, or mixed product in a fully automated and continuous way.
The powdered product is introduced into the first compartment where it is moistened by a diffuser, and a double-helix mixer is responsible for quickly and effectively dilute the product..
The diluted product moves to the second compartment through a siphon tubing system where another mixer is installed, responsible for keeping the product circulating, optimising the preparation time.
The final solution is stored in the third compartment where capacitive or ultrasonic level sensors are installed, needed for the complete automation of the process. Depending on the detected level, they send signals to the control cabinet, which acts on the different elements of the equipment (water inlet, reagent dispenser, or mixers).
One of the main advantages of the POLIFLOC° range is its ability to precisely and completely regulate the reagent supply depending on the water inlet flow rate.
By installing a pulse emitter in the input manifold, and a frequency converter in the control cabinet, the equipment’s software regulates the speed of the dispenser’s dosing screw according to the entry flow reading.
The main advantages of this control system are the significant savings in reagent, the optimisation of the preparation time, and the homogeneity of the final production.
Las principales ventajas de este sistema de control son el importante ahorro de reactivo, la optimización del tiempo de preparación y la homogeneidad de la producción final.
