EXPERIMENT#5 Removal of Contaminants in water sample (JAR TEST) Prepared by: Engr.Iftikhar Azim Introduction Naturally occurring silt particles suspended in water are difficult to remove because they are very small, often colloidal in size, and possess negative charges, and are thus prevented from coming together to form large particles that could more readily be settled out. Jar Test: Find a clear glass jar with a screw top lid (maybe pint-to-quart size, like a Mason jar), fill it three-quarters full with lake water (not directly from the surface, but collected just under the surface), and set it in your refrigerator where it can be left without being disturbed overnight. Granted, a good, depend-able six-station jar tester isn’t cheap. 0000009300 00000 n (prior knowledge, jar or pour tests) – incumbent or blank – coagulant – moderate charge anionic flocculant – low charge anionic flocculant – low charge cationic flocculant – moderate charge cationic flocculant – ph phase 2. products surrounding best general program (using appropriate test) This test provides information on the effect s of the concentrations of t he coagulants, mixing of the raw water, and the wat er quality parameters such as pH and alkalinity on the coagulation process. 2. there is a small possibility (<2%) that the algae in your particular test happen to be non-buoyant species for blue-greens, resulting in a false negative test.
