    EFFICIENCY OF WASTEWATER TREATMENT BY A MIXTURE OF SLUDGE AND MICROALGAE
    (University of Eloued جامعة الوادي, 2017-09-01) Khaldi, H.; Maatoug, M.; Heilmeier, H.; Dellal, A.
    A combined system using the microalgae from South Africa and the sewage sludge from Algeria has been tested, in order to study the efficiency of wastewater treatment by mixtures of microalgae / activated sludge, five bioreactors were installed with different inoculation rates (microalgae / activated sludge) B1: 100% algae, B2: 90.90%: 9.1%, B3: 83.33%: 16.67%, B4: 50%: 50% and B5: 16.67: 83.33. The best removal percentages were measured as: 76.36% for PO4-P, 94.90% for NO3-N, 90.42% for NH4-N and 65.73% for COD, in the combined system. Except in the case of COD, there were highly significant effects of different inoculations rates on yield. The best results are those of the bioreactor B5. These results suggest that the nutrients in the wastewater can be effectively eliminated by co-cultivation of micro-algae with bacteria (activated sludge).

    Phytoecological Study Of Tetraclinis Articulata In The Woodland Of Beni Affene, Sdamas Chergui (tiaret, Algeria)
    (University of Eloued جامعة الوادي, 2017-05-01) Azzaoui, M. E.; Maatoug, M.; Berrayah, M.
    The Mediterranean flora is definitely considered as an exceptional diversity that deserves particular attention to be conserved. This work aims to quantify the floristic diversity of Tetraclinis articulata of Beni Affane located at the woodland of Sdamas Chergui (Tiaret, Algeria). The factorial analysis of correspondences allowed us to jointly process the floristic and ecological variables, and confirm that there is presently an original floristic facies of Tetraclinis articulata. This study area contains 13 families and 21 species, where the dominating biological type is Chamaephytics (52 %). We have described as well five frequent species: Tetraclinis articulata 33 %, Pistacia lentiscus 11 %, Globularia alypum 8 %, Phylleria angustifolia 9 %, Rosmarinus tournefortii 15 %.
