This has led to many water quality problems including increased purification costs, interference with the recreational and conservation value of impoundments, loss of livestock and the possible sub-lethal effects of algal toxins on humans using eutrophic water supplies for drinking.OUR SOLUTIONS FOR YOUR NEEDSSECONDARYTREATMENTSECONDARYCLARIFICATION AQUADAF® DENSADEG® DUAL MEDIA FILTERSORDegremont Technologies has two solutions to meet the more demanding effluent standards.
