Jar tests are used as a control test for plant operations. Aluminum or iron salts can be used to for coagulation of particles and to form flocs that can settle out. Coagulation and flocculation tests provide the optimum dosages to remove turbidity and color‚ along with secondary effects such as adjusting pH. Jar tests also provide information on the amount of energy needed to provide the coagulation and flocculation treatments‚ as well as settleability of the flocs‚ and clarity of the water

change over time of the relationship between constituent concentration and flow (Hirsch‚ Slack‚ and Smith). My hypothesis for the Chevy Chase street runoff water sample is that it will have the highest turbidity out of the other water samples. I predict that if the street runoff has the highest turbidity‚ then it will also be the least safe for people to drink. Materials and Methods: When testing for the presence of chemicals in the water sample‚ we also

organism’s biotic potation. Procedure During this exercise the population growth of the bacteria Escherichia coli (E.coli) will be measured. If the conditions are right‚ the E.coli population will grow more rapidly the longer it stays in that area. Turbidity‚ meaning cloudiness‚ will be how the tubes are measured to give the results of bacterial growth. The more turbid the broth the more bacteria count the tube will contain. For this particular exercise‚ a broth has been

Our p-value for this test which showed that the difference between the sample means between the two groups was significant was .006. Also for the control group‚ the turbidity level was measured to be 3.23NTU and the Q-value for the control was 89. Whereas the experimental group had a turbidity level of 5.63NTU and a Q-value of 84. This resulted in a difference in turbidity that was 2.40NTU and a difference in

natural world. The chemistry of the stream affects the ecosystem of the stream which includes people who utilize the water of the stream for various uses. Many factors play a part into the chemistry of the water such as the temperature‚ the pH‚ the turbidity‚ the conductivity‚ and the dissolved oxygen (A.K.A. DO) (1). Those are the focus of this study. Temperature and dissolved oxygen are both related to each other. The dissolved oxygen is inversely proportional to the temperature of the water.

next step is testing the turbidity of the water. To test the turbidity you would use the colorimeter by pouring the water into a the clear square container and close it‚ it should have like 3/4s of the container of the water. And you would record the data that the labquest says‚ the turbidity of normal water is 0. You would do those same steps for the dirty water before the filter and record the data‚ the data shows the pH to be 5‚ the conductivity to be 4280‚ and the turbidity to be .70. Finally you

and compared I accepted my hypothesis but also rejected a part of my hypothesis. I reject that both streams have a high turbidity level. I believe this could be an error in our testing. Our sample was taken the same day as the testing and this is the recommended procedure for testing turbidity. That leads me to believe that we had an error in the way we tested for the turbidity. I accepted the prediction I had made as true. Herbert Run did have a better water quality than Commons stream. Herbert

this experiment confident that we were going to be able to keep our fish alive which was proven wrong mid-way through due to high levels of turbidity and the state of the fish. After collecting all of our data‚ we maintained a healthy terrestrial level and a good PH level which came as a surprise due to the death of our aquatic fauna and the levels of turbidity. In summary the project was a challenge in a sense of trying to keep our fish alive and whether or not the fish was retrieving enough nutrients
