Treatment of heavy metals by nanofiltration present in the lake Reghaia

The wetland of the lake Reghaia closes significant potentialities and historical, cultural, scientific, economic, biological values. The establishment of the industrial park and the urban development of Reghaia and Rouiba constitute one of the sources of contamination. The volume of waste water zone is estimated at more than 20,000 m(3)/day. In order to improve quality of water we introduced into our study the nanofiltration like a means of treatment to control the ionic concentration divalent and trivalent (sulphates, chlorides, sodium and many metal ions made up organic to give a better watery life. The membrane used is Nanomax50 of surface 0.37 m(2) and pore size approximately equal at 1 nm. The load of the surface of the membrane overall is negative. The permeability of the membrane is of 10(-6) m/s bars.
