Abstract

Treatment performances of two wastewater treatment plants (WWTPs), located in North-Eastern Algeria (Souk-Ahras and Sedrata) were tested using ASM1 model. The model, to be considered as a decision tool for the appropriate management of activated sludge systems, served for the prediction of both WWTP behaviours under different operating conditions. In Sedrata WWTP the first management scenarios is based on an increase of inflow rate, taking into account a new transfer volume from a nearby zone. In a second scenerio, the ultimate flow of 40 000 m3·d-1 is estimated. Regarding Souk-Ahras WWTP, three scenarios were tested. The first tested the impact of an increase of the extraction flow rate and yielded a reduction by 37% of sludge production. The second dealt with the management of the mass budget of substrata and biomass. Finally, the third application was devoted to the estimation of the plant ultimate capacity, estimated to be 60 000 m3·d-1.

Abstract

Species with fragmented populations and low population size often display low within-population genetic diversity and strong among-population differentiation. Laurus nobilis L. (Lauraceae), common laurel, has a scattered distribution throughout the Mediterranean, with only few autochthonous populations. Our goal was to elucidate if this species has range-wide genetic structure and if planted material can be traced back to its origin. Genetic diversity was investigated using 4 polymorphic nuclear microsatellites (nSSR) transferred from two species of Lauraceae. Sixty-six laurel trees were selected from 7 widely separated populations within the Mediterranean distribution area of the species. A total of 34 alleles (9 alleles per locus on average) were found. Mean genetic diversity within-population (Hs), was 0.558. Genetic differentiation among populations (GST = 0.243) was high compared to that of other angiosperms. Laurus nobilis can be separated into two main gene pools, one from western (Tunisia, Algeria and France) and the other from eastern Mediterranean (Turkey). The Algerian, Tunisian and French populations presented a strong genetic similarity, compatible with the fact that North African laurel populations could be recently introduced from north-western Mediterranean stock.
