Wastewater chemicals in the metal working industry

Depending on the type of metalwork, different kinds of wastewater are produced, each of which brings special problems.

With the optimised use of wastewater chemicals, regulations for the protection of the environment can be complied with, fresh water consumption can be reduced, high disposal costs can be reduced, demands on the budget lowered and difficult wastewaters (which until now had to be disposed of without treatment) can be treated.

We supply the following chemicals for the metal working industry:

•    Polymer flocculants
•    Metal-binding agents
•    Adsorbents
•    Pre-splitting agents
•    Chemicals for the treatment of barrel finishing wastewaters
•    Odour binding agents
•    Defoamer concentrates

Challenges in the metal working industry

Slide grinding wastewaters containing compound particles and swarf can simply be subjected to preliminary treatment with our powdery POLY SEPAR® AM and our liquid product mixtures.

Oil residue from cooling lubricant emulsions can be targeted, destabilized and creamed with several of our products.

Chemicals for electroplating

Our POLY SEPAR® CFL, CFM products pre-treat waters from concentrate or degreasing baths in electroplating so they can be collected by regular wastewaters.

With electroplating and anodized wastewaters containing compounds or many metals our metal-binding agents help to completely remove residue.

Wastewater chemicals for varnishes and paints in the metal working industry

Our special POLY SEPAR products remove, coagulate or flock varnish-, wax-, and paint residues from wastewaters.

Removal of offensive smells in metal working

Our bacteriostatic products POLY SEPAR® KS 300 and KS 400 inhibit the development of sulphurous, toxic and odorous gases produced by bacteria.

Recycling of heavy metals in the metal working industry

With our products heavy metals, generated by working on precious metals, can be specifically flocked, precipitated and so recycled.
