Abstract
The research in this thesis is motivated by changes in the water quality of the Jagir River, Surabaya due to seasonal changes which result in high turbidity, TSS and COD values. This is caused by the presence of suspended materials, both organic and inorganic. If it exceeds quality standards, it will have an impact on life in these waters. The important thing in sedimentation is the speed of deposition. The use of a plate settler can help increase the settling speed, so that removal efficiency can also increase. Installation of the plate settler takes into account a certain inclination angle. Because the value of the inclination angle will also affect the surface loading rate. The formulation of the problem in writing this thesis is (1) What is the influence of the inclination angle of the plate settler on the efficiency of turbidity removal, TSS and COD? and (2) What is the relationship between the plate settler inclination angle and the increase in surface loading rate?. This research began with taking water samples, testing coagulation and flocculation using a jar test, carrying out the research using a laboratory scale sedimentation reactor and final testing of turbidity, TSS and COD values. The variations in this research are the settling time and inclination angle of the plate settler. The statistical analysis method used is multiple linear regression. The results of this research indicate that the use of a plate settler with a certain inclination angle has an influence on turbidity removal, TSS and COD. If the position of the plate settler is relatively upright, it will be difficult for the floc to hit and slide on the plate settler. And if the position of the settler plate is relatively horizontal, the floc tends to stick/join the plate wall and will slide for a long time. Based on statistical tests, td and angle can influence the turbidity value by 13.80%, influence the TSS value by 78.69%, and influence the COD value by 85.24%. And the rest is influenced by other factors not examined in this study. And the smaller the value of the surface loading rate, the greater the allowance will be. Surface loading of 51.97 m3/m2.day and detention time of 75 minutes can produce high turbidity, TSS and COD removal efficiency because the surface loading rate value is represented by the large surface area.
