Algeria has a fragile ecosystem, characterized by a relative scarcity of water resources and their preservation is a vital imperative. The excessive intake in the natural environment of nitrogen and phosphate load in wastewater, from agricultural activities, domestic and industrial pollution, represents a pollution threat and a serious danger to the aquatic environment. Municipal wastewater contains various wastes, and usually consists of about 99.94% liquid and 0.06% solids. If this wastewater is not treated or improperly collected, it can affect both public health and environment. In our study, we will focus on the biological treatment by natural lagoon and activated sludge, which suits perfectly our country, where space and climate are favorable factors; our main objective is to eliminate the maximum existing phosphorus in wastewater by these biological treatments, which can actually eliminate total phosphorus. Through these modes of treatment we try to remove the maximum of organic matter and phosphorus in the wastewater. Consequently, the receiving environment is preserved.

Abstract-Adrar, a city located at the extreme western south of Algeria, uses underground water as the unique source of drinking water, unfortunately, this ground water is subject to contamination by the ceaseless urban water discharged by the city.The objective of this work is to examine the efficency of the biological treatment of this raw waste water through natural lagoon; prior to their release into the receiving environmlent ; by the removal of elements characteristics of pollution mainly DCO, MES, P and N, we have found a removal efficiency in DCO of 63%, in MES 66%, nitrites and nitrates70% and 40% of phosphorus. These findings are considered satisfactory and hence prevent the contamination of drinking water and preserve the quality of Adrar's ground water.

Abstract-The most important nutrients in controlling water quality are: carbon, nitrogen and phosphorus. They are essential to the growth of all living organisms. These are the nutritional pillars of bacteria, fish, trees and humans.Unfortunately, when a water body or plan becomes rich in these nutrients, particularly phosphorus, this causes some organisms such as algae to grow in abundance which makes the environment ugly. These algae are usually undesirable and may inevitably cause changes in pH, dissolved oxygen, colour and turbidity of the water environment, hence the environment becomes eutrophic and its color turns to green.To address and solve the eutrophication issue, the amount of phosphorus discharged into the receiving milieu must be reduced; and this constitutes the main purpose of our research.We proceeded so as to make a physico-chemical phosphorus removal from urban waste water. The physico-chemical treatment is based on looking for and finding the optimal dose of the various added coagulants.The aim of our work is to confirm the efficiency of the chemical treatment through use: lime, ferric chloride and aluminum sulfate as coagulant for this treatment.
