Precipitants

Areas of application for precipitants

Precipitants are used in the most varied applications in communal, industrial and biological wastewater treatment, for example in:

• Phosphate precipitation
• Bonding of hydrogen sulphide
• COD-reduction

In addition there are numerous applications in

• Dairies
• Slaughterhouses
• The delicatessen industry
• The paper and cardboard industry

Precipitants as a solution

SEPAR CHEMIE has a large selection of precipitants. The POLY SEPAR® CFX-range  is based on fully polymerised aluminium chlorides or on highly concentrated, modified poly-aluminium chlorides as well as iron salts.

• Aluminium  sulphate
• Poly-aluminium chloride
• Aluminium(III)-chloride
• Sodium aluminates
• Iron(II)-chloride
• Iron(III)-chloride
• Iron(III)-chloride sulphate

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.
