Coagulation Diagrams for Flocculation Monitoring in Water Treatment

A study constructing coagulation diagrams from bench tests using jartest equipment to evaluate water turbidity removal. The work used iron-free aluminum sulfate as a coagulant in dosages from 5 to 100 mg L-1 and coagulation pH from 3 to 9, investigating three sedimentation velocities. Daniel Bartiko authored this research, which is available via Open Access on paperswithcode.

Use Cases

• Optimizing coagulant dosage based on pH and turbidity removal efficiency described in the study
• Analyzing the relationship between sedimentation velocity and final water turbidity as investigated
• Modeling coagulation-flocculation performance using diagrams constructed from jartest data
• Comparing floc characteristics for continuous monitoring techniques mentioned in the description

Strengths

• Experimental parameters are precisely defined, including coagulant dosage range (5-100 mg L-1) and pH range (3-9)
• Study identifies optimal operational conditions, such as pH 6.5-7.5 and dosages above 15 mg L-1 for turbidity removal
• Results quantify performance, reporting turbidity removal to less than 1 uT at the lowest sedimentation rate

Limitations
