Detection and Diagnosis for Blue Green Algae Toxin-Producing in Al-Rasheed Drinking Water Plant in Baghdad

Abstract

Diagnosed algae in the final drinking water tanks for the liquefaction at Al-Rasheed plant located in the city
of Baghdad on the Tigris River Rusafa site, showing through results seen that algae greens bluish are
striking and through examination bio-counting biomass of algae toxin-producing of the Division of algae
greens bluish and along the seasons of the year the quantity of high prosperity is vital, reaching numbers of
algae 10400002, 4046, 2844 and 3497 cells/ liter during the summer, spring, winter and autumn season,
respectively, in the pelvis final drinking water, represented by algae wandering Chroococcus minor,
Microcystes aergenasa and Oscillatoria limnetica which Almsoalh for excretion of toxins moss, algae while
conjoined prevailed more than wandering prevailed algae Lyngbya connectens, M. aergenasa, O. limnetica,
O. tenuis, O. geitleriana, O. formosa, O. subbrevis, Nostoc linkal, Phormidium tenue and Anabaena sp, but the
most important algae conjoined within the basin final drinking water, represented by Phyto Anabaena sp,
Chroococcus minor, Lyngbya connectens, Microcystes aergenasa, Oscillatoria limnetica, Nostoc carneum and
Phormidium tenue, which helped the algae to flourish in this density is a memorial in concentrations of plant
nutrients of nitrates, nitrites and ammonia and phosphorus concentration of 3.01, 1.2, 1.47 and 0.6 mg / l
during the summer and 1.84, 0.2, 0.23 and 0.3 mg/ l during the spring and 0.76, 0.2, 0.09 and 0.1 mg/ l,
respectively during the winter, 0.736, 0.3, 0.13 and 0.1 mg/ L, respectively, during the autumn and Bekorh
stood at 57.0 , 19, 16 and 11.5 UNT, respectively, during the seasons of the year set forth above, and some
other nutrients such as calcium, sulfur and aluminum are shown in the results note that all of the calcium,
ammonia, turbidity and electrical conductivity are higher than the permissible limits of the specification for
the Iraqi drinking water
