Abstract
This
work is aimed to study the characteristics of some wastewater in Sulaimani
city. Water samples were collected monthly from October 2018 to May 2019 from four sites, two of them Site1:Tanjaro River before
bridge,Site 2:Tanjaro River after bridge along
Tanjaro river , Site3:kana swra and
Site4:Awbara from weast water of Sulaimani city box channels which finally flow into Tanjaro river . To
represent their water quality some physical , chemical and Biological analysis were conducted. The mean value of pH for all studied sites was
found to be above 7 . The value of Electrical conductivity(EC) in Sites 1,2,3 and 4 were ranged between(407-601 µs/cm),(
266-585 µs/cm) ,( 773-1004 µs/cm) and(398-975 µs/cm)respectively, Turbidity
ranged between(42-1001 NTU),( 57-986 NTU),( 32-1010.5 NTU) and(41-643 NTU) in
Site 1,2,3 and 4 respectivly and Chemical Oxygen Demand (COD) value in Site 1,2,3 and 4 were ranged
between(251-975.5 mg/L),( 275-926 mg/L),( 354-1025 mg/L) and(452-1025 mg/L)
respectively. A total of 114 algal taxa were identified belonging to 7 classes,
63 taxa belonged to Bacillariophyceae species, they were the most abundant
group (4 taxa belong to centrales and 59 taxa belonging to pinnales), followed by 24 taxa of Cyanophyceae ,22 taxa
chlorophyceae, , 2 taxa Pyrophyceae and 1 taxa for each of Euglenophyceae ,
Rhodophyceae and Xanthophyceae. Higher phytoplankton density was recorded in Awbara (58269.44ind×103/L),
while the lowest density was recorded in
Tanjaro River after the bridge which was (14300.2ind×103/L) .
