Crystallization inhibitors

Prevention of crystallisation and calcification in water pipes, vacuum pumps and paper machines

POLY SEPAR® Antiscaling agents or crystallisation inhibitors are concentrates of polyphosphates, polyacrylates and additives for the prevention of crystallisation and calcification in water pipes, vacuum pumps and paper machines (in the paper industry).

Application of antiscaling agents

POLY SEPAR® Antiscaling agents are low viscosity liquid products, which can be dosed undiluted with a piston diaphragm directly from the barrel or IBC into the water circuit.
The necessary dosage depends on various factors and must be experimentally determined.

Products for crystallisation control

POLY SEPAR® C 1: The antiscaling agent prevents and removes calcium carbonate (lime scale). It is used with paper machines in front of spray nozzles and suction rolls. POLY SEPAR C 1 is approved according to the 36th recommendation of the BfR (federal institute for risk assessment). This crystallisation inhibitor significantly prolongs the running time of the paper machine.

POLY SEPAR® C 3: The antiscaling agent shows excellent dissolving and dispersion properties for the removal of existing lime scale in waste water and at paper machines.

POLY SEPAR® C 4: This crystallisation inhibitor fights crystallisations through MAP (magnesium-ammonium-phosphate = STRUVITE).
