“…The results showed that there are clear seasonal changes between the air and water temperatures of the study area, and the seasonal changes were variable, as the highest value recorded for the air temperature in the summer season was (41) Celsius, which did not differ significantly from the autumn season, which differed significantly from the rest of the seasons, while it reached its lowest value (11) Celsius during the winter season, while the highest water temperature was also in the summer (40) Celsius, which did not differ significantly from the autumn season, which differed significantly from the rest of the seasons, while the lowest temperature of the water was recorded in the winter (25) Celsius, which It did not differ significantly from the autumn season, which differed significantly from the rest of the seasons. Observed through the current study a significant correlation between the temperature of air and water, as it corresponded with it in terms of rise and fall [39], stated that temperatures have a significant impact on the process of photosynthesis, in addition to their direct impact on vital processes in the plant body, such as the transfer of nutrients, the absorption of elements, the formation of pigments . Water pollution leads to a change in the nature of the water as a result of adding harmful substances to it or as a result of an increase in temperature or human interventions, which affects the water quality of plants.…”

The aim of the study was to find out the chemical content of some algae, Enteromorpha and Cladophora, and some selected aquatic plants, Typha domingensis, Phragmites australis and Schoenoplectus lacustris. were studied Ashes, fats and mineral elements, which include magnesium, phosphate and nitrogen, in addition to studying the physical and chemical properties of water at different times of the seasons. Enteromorpha moss showed the highest percentage of ash which amounted to (14.32%), magnesium (0.43%) and phosphate (2.73%) while Cladophora moss showed the highest percentage of fat which amounted to (7.28%) and nitrogen (3.92%). The plants showed clear significant differences in different seasons where the results showed that the highest value of ash for Typha domingensis was in spring (11.11%), for Phragmites australis in summer (12.43%) and for Schoenoplectus lacustris in autumn (16.21%). As for fats the highest value of fats was in the spring season for the Typha domingensis plant (3.10%), for the Phragmites australis plant in the autumn season (1.51%), and for the Schoenoplectus lacustris plant in the summer season (2.21%). As for magnesium, the highest value of magnesium was in the winter season for the Typha domingensis plant (0.25%), for the Phragmites australis plant in the summer season (0.76%), and for the Schoenoplectus lacustris plant in the autumn season (2.45%). As for phosphateits highest value was in the autumn season for the Typha domingensis plant (0.26%), for the Phragmites australis plant in the spring season (0.32%), and for the Schoenoplectus lacustris plant in the autumn season (0.24%). Also the physical and chemical properties of water showed great variations in different seasons as the highest recorded value of air and water temperature in summer was (41) and (40) Celsius respectively. As for the pH, the highest value was recorded in the winter season (8.16), and the nitrates recorded the highest value in the autumn season (45.35) mg / L.

“…The results showed that chemical treatments have a significant impact on the growth of that plant. Although this plant is considered harmful to aquatic wealth, there are many studies showing the extent of its utilization [12]. Applying a phytoremedation system to treat sewage with local alternatives and using it on the agricultural side.…”

Ceratophyllum plant covers most waterways, including lined channels and trenches. This plant causes a loss in the amount of runoff, velocity of water in the channels, and reduces the drainage rates. This research aims to design and manufacture a machine to clean the water intake outlet for the filtering station of Karbala drinking water by removing plankton, Ceratophyllum plant and algae, and throw these impurities out by means of adding catchers to the machine. As a result of gathering of these floating plants during runoff, it around water surrounding channels intake that were went to suction pumps, so that the channels are blocked. That is why, the workers would be frequently getting down to the river for cleaning after shutdown of the pumps. After studying the topic and coming up with an idea, according to which the design and technology drawings of the machine and determining the location where the device will be tested after implementation at different speeds (30, 60, and 100 m/min.). Three types of catchers (holders) of Ceratophyllum Plant and other Plankton were used. It was obtained that the cross-sectional area of the flow of the machine is greater than that of the suction pipe of the water purification station. The best linear speed for this machine was 30 m/min, which removes impurities by 2.2m3.
