·Flocculators and Jar Testers are Designed for a Range of Applications -ASTM D2035 compliant method
- Testing the efficiency of flocculation or precipitation agents - Leaching test, made on solid wastes to be sent to the dump that uses diluted acetic acid or carbon dioxide-saturated water to detect the presence of toxic heavy metals
·Jar Testing Entails Adjusting the Amount of Treatment Chemicals and the Sequence in Added to Samples of Raw Water Held in Jars or Beakers - The sample is then stirred so that the formation, development, and settlement of floc can be watched just as it would be in the full-scale treatment plant
·Why Perform Jar Test? - Optimization is the key to running the plant more efficiently
- The results of several different chemical treatments can be compared -Alternative treatment doses can be tried without altering the full-scale treatment plant -Save money by avoiding overfeeding or overdosing, especially with coagulants; this may not hurt the quality of water, but it can cost a lot of money
·When to Perform Jar Test? - Seasonally, monthly, weekly, daily
- The more frequently it is done, the better the plant will operate - There is no set indication about how often jar testing should be conducted
·How to Perform Jar Test - Each beaker is treated with different doses of chemical - For each sample, usually raw water, a number of beakers (jars) are filled with the same amount of aqueous sample - Other parameters may be altered besides dosage, including chemical types, mixing rate, aeration level/time, filtration type, etc.
- By comparing the final water quality in each beaker, the effect of the different treatment parameters can be determined and the best formula can be reproduced on a large scale
