The NEYRFLOC polymer preparation unit is intended for the preparation and continuous dosage of flocculants. The Neyrtec Mineral polymer preparation unit allows the preparation and distribution of a flocculant solution in sufficient quality and quantity. Both the preparation concentration and the distribution dosage are easily adjustable. This equipment is essentially composed of a storage unit for powder dosing, a tank with 2 or 3 compartments (integral or separate) including an agitator, the water supply, the dosing pump set, a static mixer, 1 control panel and a dispensing station.
