| Abstract | ||
| This study is concerned with studying the relationship between algal count (Diatoms, Green algae, Blue green algae), turbidity, pH, temperature, residual aluminum, alum and chlorine dose during one year (2018) at five surface plant intakes (Nag-Hammadi, Dishna, El-Salhyia, Qeft and Qous plants) at Qena governorate. Results show that alum dose had a linear relationship with temperature and turbidity; this indicates that the amount of chemicals and doses increases with increasing algae count in water intakes. In Nag-Hammadi plant the highest alum dose was recorded in January, 2018 whereas the least alum dose was in August 2018, when the lowest algae count was recorded. So, it is advisable and less cost to study the algal count along one year for the expected intake for any new plant to know the required chemicals that this plant needs in the future. In addition, we have to take into consideration that the seasonal variation in these algal counts, affects the chemical dosages required for water treatment. | ||
