Wastewater Effluent Discharge: Effects and Treatment …
ipcbee.comeutrophication and algae bloom, thus having negative impacts on nature conservation, recreation and drinking water production, it is necessary to control the emission of phosphates from discharges of wastewater (van Larsdrecht, 2005). The excess content of phosphorus in receiving waters usually leads to extensive algal growth (eutrophication).

www.eolss.netEutrophication (i.e., nutrient enrichment due to human activities) in surface waters are primarily due to nitrogen and phosphorus. The most recognizable manifestations of this phenomena are algal blooms that occur during summer. Over-nutrient enrichment results in low dissolved oxygen (DO), fish kills, murky water and depletion of desirable

An Introduction to the Nitrogen Cycle - Great Lakes Aquarium
glaquarium.orgExcess nutrient runoff can cause eutrophication of lakes. Eutrophic lakes get their name from the Greek word, “eutrophus,” which means “high nutritious,” and eutrophic lakes are exactly that – they tend to have high nutrient loads, which support high “productivity” of plants and animals in the lake. The nutrient status of lakes
