Hello, I am creating a water filter using Moringa Olefiera. I need to test the effectiveness of it. I already have a TDS meter, but I can't afford a turbidity meter. What are some other ways I can test the efficiency of the filter? How can I test the effectiveness of a water filter on reducing turbidity?

Hi @Mempet, Could you use a turbidity tube like this one: https://www.carolina.com/environmental-science-water-quality/carolina-turbidity-tube-120-cm/182006.pr ?

Hi @gretchengehrke! Thanks for letting me know about this! I might actually be able to use it. However, one complication I have is the amount of liquid needed. I only have about 15 ml of liquid, so I don't know if the tube will work..

I wonder how they measured effectiveness of filtration!
