Investigation and Detection Algae Growth of Al-Rashed Water Supply/Baghdad
Abstract
Diagnosed algae present in drinking water for the liquefaction plant Rasheed located in the city of Baghdad on the Tigris River next to the Rusafa. The results are significant demonstrated growth of algae in various filtering stages of the river outlet sedimentation basin and the first basin filters ultimate reservoir of drinking water after the sterilization process, existed algae in the final basin for three algal species classified greens algae and vegetables blue and Diatom classes year, summer, spring, winter and autumn, and the number of vital reached 4937 and 3744 and 3743 and 4027 cells / liter, respectively, to varieties of algae mentioned. While rates of algal species reached basin sedimentation first for the summer, spring, winter and fall to 29 561 and 9811 and 6717 and 6534 cells / L, respectively, and the number of races and got to 39, 22, 25 and 28 genus respectively in different rows, and rates of types of algae basin filters for the same chapters to 8390 and 8465 and 3137 and 3143 cells / l, respectively, and the number of races arrived 33, 20, 16 and 20 genus respectively various Elsafov.as the results of chemical tests height of turbidity, which amounted to 57.0 and 19, 16 and 11.5 NTU respectively classes year compared to the specification of the Iraqi drinking water, amounting to 5 NTU. With the increasing electrical conductivity in the summer, this reached 1033 Sµ / cm season. With a high concentration of calcium by 11.6 and 77, 119 and 103 mg / L, respectively, compared to the classroom specification of drinking of 50 mg / L. The current study also observed the presence of toxin-producing algae in drinking water station liquefaction Rasheed represented algalMicrocystis sp and Lyngbya connectens and Nostoc carneum and Oscillatoriasp, belonging to the Division of blue algae vegetable-producing toxins produced by Global Sources types of toxins and Saxitoxins Microcystins and Anatoxin-a.
