What is it about?

This publication explored phytoremediation using local macrophytes in Balili River, Philippines. We demonstrated that local macrophytes such as Amaranthus spinosus, Eichhornia crassipes, Eleusine indica and Pennisetum purpureum planted in pilot-scale constructed wetlands can effectively remove water pollutants at 3–4 days hydraulic retention time. Among the macrophytes, P. purpureum generally have the best pollution reduction efficiency. Our study revealed comparable or even better pollution reduction efficiency of local macrophytes than commonly used ones such as Phragmites spp. and Typha spp.

Why is it important?

Our results clearly showed that the solution to the pollution Balili River is within our grasp. We just need to tap the documented phytoremediation potential of our local macrophytes, particularly P. purpureum, in a full-scale CW.
