Speciality chemicals
Chemtrade International B.V. also offers speciality chemicals for wastewater treatment.
Optimised chemistry for wastewater treatment
Many of our speciality products are reaction separation agents: formulated powders combining several functions, generally:
- Coagulation
- Absorption
- pH control
- Flocculation
Combining these steps makes operation straightforward, because the operator does not have to dose several separate products.
Examples include heavy metal complex breakers for metals that are complexed in wastewater and cannot be separated using standard coagulants.
We exclusively supply these products from EFA Chemie GmbH in Germany, giving access to extensive sector knowledge. EFA’s in house research and development can formulate specific products for many wastewater types to achieve optimum results. Different streams may need different flocculants or different proportions in the formulated powder.
