Jar test lab report doc. PH and turbidity of waster sample was measured.
Experiment 7 Jar Test Coagulation And Flocculation
Jar test date of experiment.
. We can overcome it by using buffer as the same amount of alum that we added. View Jar Test Lab Reportpdf from ECW 568 at Universiti Teknologi Mara. By the aid of jar test apparatus we used various alum dosages from 0 and 200 mgL.
In other words jar test helps to determine the right amount of treatment chemicals. While stirring the sample use an eyedropper to add the precipitant until the ORP value drops rapidly by 150mV typically to. What is jar testing.
ENVIRONMENTAL ENGINEERING LABORATORY ECW568 OPEN-ENDED LAB MARCH 2021 AUGUST 2021 TITLE OF EXPERIMENT. Pour a sample of untreated wastewater into a beaker ex 300 ml. The second highest turbidity reading is 207 which is belongs to jar 5.
The solution can be achieved by taking 125 ml of flocculent adding it to 500 ml of water mixing thoroughly by shaking or mixing. JAR TEST 10 OBJECTIVE. JAR TEST DATE OF.
Because it mimics full-scale operation system operators can use jar testing to help determine which. While mixing adjust the pH using caustic soda or sulfuric acid to the optimum pH for hydroxide precipitation of mixed metals ie. Ayuni syahirah binti baharun.
Out of 20. To conduct jar test. JAR TEST 10 OBJECTIVE.
We reach this conclusion base on the fact that the turbidity minimum at 121 NTU. The turbidity level of jar 1 and jar 2 are 187 and 176 respectively. To show the effectiveness of chemical treatment in a water treatment facility.
Furthermore after determining the optimum alum dosage for natural river water the optimum pH value for color removal was studied by varying the range from 45 to 85. In each beaker add 1ml of the flocculant solution and mix for 1 minute. Jar test is a pilot-scale laboratory test that simulates coagulation or flocculation with differing chemical dosesThe purpose of this test is to estimate the minimum coagulant dose required to achieve certain water quality goals.
Each jars are dosed with different volume of alum using the pipette. Download View Jar Test Lab Report as PDF for free. Adding 1ml of a 025 solution of flocculant to 500 ml of water equates to a dosage of 5 ppm.
Jar testing is a method of simulating a full-scale water treatment process providing sys-tem operators a reasonable idea of the way a treatment chemical will behave and operate with a particular type of raw water. To show the effectiveness of chemical treatment in a water treatment facility. To evaluate coagulation efficiency.
The jars are then placed under the paddles of the jar test apparatus and the paddles are lowered to the same depth in each jar. Jar test lab report doc. Atiq fikri bin marzukhi 2018272762 4.
To determine the most effective dosage of the. Six 1-L jars were filled with 1000mL of the water sample. Typically a 025 solution in water is created.
Jar Tests Determination of optimum pH The jar test a laboratory procedure to determine the optimum pH and the optimum coagulant dose A jar test simulates the coagulation and flocculation processes Fill the jars with raw water sample 500 or 1000 mL usually 6 jars Adjust pH of the jars while mixing using H 2 SO 4 or NaOHlime. Ahmad nabil hamkah bin mohd noor 2018439194 3. Based on the results jar 6 which acts as a control sample has the highest turbidity reading that is 205 while jar 3 has the lowest turbidity reading that is 112.
Substances and turbidity in either cases. Jar 4 has the second lowest turbidity reading that is 114. 60 DATA ANALYSIS 1.
Abdullah amin bin abdol razak 2018435402 2. After we analysed the data we have decided that the optimum dosage of alum for this experiment is 5mgL. Ec2206a1a group members 1.
To conduct jar test. It is because alum will make water more acidic. Based on what we found in the experiments with the.
The lowest dose of chemicals that provides satisfactory. Environmental engineering laboratory ecw open-ended lab march 2021 august 2021 title of experiment.
