I have to do a EEI for school about turbiduty of water and finding the most cost effective method for purifying a sample of water. My group was planning to do a standard test where we use materials such as filter paper, cloth, sand, gravel, etc. and run the turbid water through it. As our school has no turbidometers we wanted a way to have some quantitative data. To do this we were planning on conducting a dissolved oxygen test (wrinklers method) as we found some sources linking turbidity to oxygen levels. Would this be a valid test? Would the filtered water need to sit overnight, for example, before we tested the DO?
And help is appreciated!!!
