Beneficial Use of Municipal Sludge in the Ocean

摘要: The micronutrients in municipal sludge enhance ocean productivity much the same way as they plant when applied to land. organic solids of can also directly production valuable biomass ocean, particularly benthic biomass. Studies and wastewater discharged into marine waters throughout world have demonstrated that, if application rate or were optimized by utilizing larger sites, beneficial enhancement could be achieved without adverse effects associated with excessive rates overfertilization. Existing evidence indicates although not risk- disadvantage-free, use sludges is a viable management option which, some instances, likely fewer negative environmental side than other feasible options.
