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. Results Report all results in a Table format. Take 1000 ml of given sample in 6 beakers. The jar test, device consists of a number of stirrers (4 to 6) provided with paddles. Plot turbidity and pH as a function of coagulant dose. D1193 Specification for Reagent Water. Expound on the information that is presented in this handout. D1293 Test Methods for pH of Water. Reagents required: Alum solution (1 ml containing 10 mg of alum) Procedure : 1. To evaluate soil texture, use a simple jar test to determine the percentages of sand silt, and clay. Turbidity meter. northstar chemical, inc. jar test report plant: city of lake oswego date: 7/9/08 purpose of test: testing polymers and coagulants for intertie project stock solutions: 0.1% soln of various polymers, full strength coagulants engineer: joe f randolph water characteristics source turbidity colour uv … Discussion If you would like to receive a response, please Register or Log In first! Materials: Straight edged, clear jar; Permanent marker; Ruler; Watch or stop watch REPORT FORMAT Introduction Describe the pur pose of jar testing and summariz e the theoretical background. The jar test If your lake or pond water appears very green, the jar test can help determine if the color is from blue-green algae, or just an overabundance of more beneficial types of planktonic algae. 2. D3370 Practices for Sampling Water from Flowing Process Streams. Soil Texture Analysis “The Jar Test” Procedure. The paddles can be rotated with varying speed with the help of a motor and regulator. The aluminum sulfate has a specific gravity of 1.26 and the solution has a strength of 52.2 percent. 2. environmental engineering laboratory ecw 568 open-ended lab report title of experiment: jar test date of experiment: 27 april 2020 group: ec220 6b1a group members 1. mu'az bin mohd nasruddin (2018674636) 2. aliff najmi bin zulkipli (2018287996) 3. avon janius (2018425206) 4.

Quality report was validated by compar ing the current study results to BIS 10500 : 2012. A JAR TEST STUDY ON THE USE OF ALUM FOR TURBIDITY AND NUTRIENT REMOVAL IN CANYON LAKE, CA FINAL REPORT Submitted to MWH Americas, Inc. Arcadia, CA for Elsinore Valley Municipal Water District 31315 Chaney St, Lake Elsinore, CA 92531 Submitted by James A. Noblet with research assistance by Emmett Campbell and Graciela Cervantes 1. Beaker, burette, pipette. Summary; Files; ... Code; Tickets; Report Abuse or Inappropriate Project. Jar test is simple device used to determine this optimum coagulant dose required. Jar Test Procedure for Precipitants, Coagulants, & Flocculants Precipitation is the chemical conversion of soluble substances (including metals) into insoluble particles. Jar testing apparatus. Once the percentages are calculated, the soil textural triangle can be used to determine the soil type. Procedure Describe the exper imental procedure. D1129 Terminology Relating to Water. 3. 2. Find the pH of the sample and adjust it to 6 to 8.5. Coagulation and flocculation causes a chemical reaction that promotes the formation, agglomeration or clumping of such particles to facilitate their removal from solution. The following is a hypothetical wastewater scenario presented with a three-step instructional method to simulating jar test results: Jar testing determined the best liquid alum dose is 6.1 mg/L.
