Pollotion is a risk that has, unfortunately, become an issue in most parts of the world; especially the developing world. The slides presented here are the summary of a study carried out to determine the effect of the use of Water hyacinth as Alternative and cheap treatment option for domestic sewage.

1. Alternative Sewage Treatment Option: The Effect of use of Water Hyacinth (Eichornia crassipes) in the Treatment of Domestic Sewage A. E. Adeniran Works & Physical Planning Department University of Lagos, Nigeria [email_address] [email_address]
