The polyelectrolyte preparation and dosing station is used for automatic or semi-automatic preparation, storage and dosing of polyelectrolytes, and allowing control over the dosage. The dosage of flocculants, which are an effective way of improving the parameters of dehydrated and thickened sludge, is controlled by a programmable controller. We offer polyelectrolyte dosing stations with one or two tanks. The stations are made of acid-resistant steel or polyethylene.
