Dredging of rivers or harbors with sediments contaminated with environmental pollutants often requires removal and deposition of the excavated masses together with a proper treatment and cleaning of the water prior to discharge back to the environment.
Kemira’s expertise in both solid-liquid separation and water treatment make us your perfect partner for such dredging of rivers or harbors.
Kemira's flocculant and coagulant product series can be used separately or in combination to obtain the optimal result for the given circumstances. We are open to also function as a discussion partner and give technical advice regarding choice of dewatering and water treatment technology and set up. Kemira has through participation in several dredging projects gained a large network of companies specialized in different parts of the dredging process.
