Project summary

Edit project overview to modify the project summary.

The goal of the project was de environmental recovery of Segura River in Murcia, Spain. Over the years, river mud has been accumulated causing problems both in wildlife’s habitat and in surrounding population because of the river flow reduction and the bad odor generated by the river mud, respectively. This project has used bioremediation in order to reduce organic component of the river mud and, therefore to reduce the mud odor. Due to bioremediation, the dredging of the river has not caused odor problems to the population

Brick application system into the river mud

Once into the river, bacteria released from the brick will start their bioremediation action
