Thank you for your video! 😁😁🙏But why the formula of calculating velocity is distance/time? Is there an explanation? Also for this calculation of performance are we assume the particles are the same size as if not the time for settlement will be different?😮😮and what is the theroy behind imhoff cone experiment? Thank youuu
I am running a lemello clarifier, it has a blow down pump, but my company replaced it with a 3x3 trash pump that is constantly running. My question is…. If this trash pump is constantly running, isn’t this counterproductive to the settling of the sludge? If so, how often should I been clearing out the sludge?
BOD is biochemical oxygen demand. This is a better test but takes longer. COD is used to estimate BOD because BOD takes 5 days to complete. COD takes two hours.
