Turbidity

life and recreational purposes of the creek. The higher the turbidity, the more opaque the water is which then evidently reduces the sun’s rays from having the ability to penetrate the surface of the water, in order to provide the sunlight needed for the process of photosynthesis for aquatic species. In order for this to successfully take place, a suitable level of turbidity must be achieved of no greater than 5 NTU (nephelometric turbidity units), which is basically referred as the maximum…

Turbidity is a reflection of the amount of fine suspended sediments in the water, which was what affected Site 2’s turbidity. Conductivity can affect organisms as high conductivity can encourage algae which can lead to daily fluctuations in both pH and dissolved oxygen levels which are harmful to organisms living…

Turbidity: - Turbidity is a degree of water clarity. Turbidity is defined as an “expression of the optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample”. Nephelometers are used to measure the intensity of light scattered by contaminants present in water such as suspended and colloidal solids like clay, silt and microscopic organisms. Turbidimeters using the principle of nephelometer compare the light scattered due to…

nitrate, phosphates, dissolved oxygen, turbidity, temperature, and pH is in the water. The stream team will look at the effect on water quality, the effect on plants and animals, the acceptable levels for swimming, sources and sources categorized, the best management practices, whether the sources are point source, or nonpoint source pollutants, and the test results. The stream team will be doing all of those topics over nitrate, phosphate, dissolved oxygen, turbidity, temperature, and pH. The…

Abstract The purpose of this experiment was to use 3 different techniques (Direct count with hemacytometer, viable count, plate count, turbidity study using spectrophotometer) to calculate the cell count and growth of bacteria, while using serial dilution. The 3 techniques were used to calculate the % viability of Serratia marcesens in a solution. Introduction Enumeration of microorganism is used to determine the amount of bacteria present in a sample. Microbiologists around the world are…

alum concentrations of 0, 5, 20, and 40 mg/L. All were subjected to the stirring apparatus at the same speed of 30 rpm for 15 minutes to allow for flocculation. Initial turbidities were taken before starting the mixing. After being mixed, they were allowed to sit and settle for 20 minutes. Then measurements of the final turbidities were taken. The second part of the lab’s setup was nearly identical to the first part. Out of the first four tests in the first part of the lab, two of the best…

fish residing in the pools, the amount of turbidity of the water in the pools, and the selection of mates. The amount of turbidity within the pools are one of the three factors that causes color variation within the guppies. Turbidity is the cloudiness or haziness of a fluid which is caused by a large amount of particles that are usually invisible to the naked eye. The more turbidity a pool has than the cloudier and hazier the water is. Amount of Turbidity within the pool’s waters Type…

In the testing stream water there will be nitrates, phosphates, dissolved oxygen, turbidity, different temperatures, and pH levels.The most important factor to stream testing is the temperature of the water. If the temperature increases the amount of dissolved oxygen decreases. (EPA and Staff, 2012)Phosphates are present in the water through human and animal wastes. (Oram, no date) Phosphates are used in laundry soaps, cleaners, industrial effluents, and fertilizers. (Oram, no date) Nitrates…

and the turbidity of the water is low then the variation of guppies will be greater because predators tend to live in habitats where the water is shallow and the turbidity is high.…

Overall, our experiment shows a correct result which our graph of turbidity versus coagulant dose have the correct pattern as the true result. However there might be error occur that make our result not accurate. The important of jar test. By performing jar tests, we can try alternative treatment doses and strategies without altering the performance of the full-scale treatment plant and easily compare the results of several different chemical treatments for time of formation, floc size,…
