Through the results of the Jar experiment, a standard for the selection and dosage of chemical reagents for removing suspended solids from sewage was established. VELP's multiple stirrers with multiple stirring speeds ensure reliable experimental results.

Removal of Colloidal Particles from Water Jar Test
In tap water treatment, there is a procedure called medicated coagulation. As the name suggests, chemicals need to be added into our treated water, but what are the functions of these added chemicals?

In the experiment of coagulation dosing, we will first prepare the same volume of water in a beaker, and then add it to the water at the same time according to different dosages. Then use a stirrer to quickly mix the coagulant and water, and then let it sit for a period of time. We You can clearly observe the generation of particulate matter from outside the cup, which accumulates at the bottom of the cup and bottle as time goes by. Finally, by analyzing the water in the upper layer, you can find the cleanest test water. This experiment is also a common "cup and bottle" experiment in water treatment. Jar test.

After this series of addition tests, the optimal addition amount can be known. This will not only effectively remove invisible colloidal particles from the water, but also reduce excess additives and be used in the purification unit of the water plant. . In addition, we will fine-tune the amount of medicine added depending on the turbidity of the monitored source water. This also shows that small experiments (cup and bottle tests) are still needed to find the most suitable conditions for different water quality conditions.
