Dosing systems for precipitants
We can provide various types of dosing systems.
Application fields of precipitants
Precipitants are usually dosed undiluted. They should be added at a point with high turbidity. The necessary dosage depends on the medium to be treated. It can lie in the low ppm range and would have to be determined through a laboratory test.
In selected areas of application with a high sheer load of flocks, consecutive dosage of a further high-molecular polymer has been proven useful.
In on site laboratory-tests our staff members recommend the optimal solution for our customers, non-binding and free of charge.
