Natural coagulant (1 reply)

Hi everyone! I am interested in conducting a study concerning the performance of a natural coagulant in sedimentation process. My focus is to use a Lady's finger fruit (also known as OKRA) and compare its performance with the artificial one, such as hydrated aluminium sulfate. Can anyone help by giving me some tips on what parameters to consider so that I can get a better result of my study?

Suggest starting with base line reagent (coagulant) screening  tests, in 100 mL graduated cylinders so you can get an initial idea on effectiveness. For best results, you may need to use some flocculants as well. Once you picked the best reagent/combo,  pre-validate using static settling tests (Kynch) with rakes, 2000 mL cylinders this time. Use the Talmadge Fitch model for unit area calculations based on your results. If your application  is commercial, validate by dynamic testing with underflow rheology validation, so you preclude any capital risks.
