Features:
Variable speed motor driven stirrers
Motor speed controller & indicator provided.
Tesca Flocculation Test Demonstrator is The present set-up is designed to conduct the coagulation and flocculation test in the laboratory. These tests are called the ``Jar Test '' which is routinely performed by the water treatment operators in the industry. This test indicates the optimum chemical dosages for the removal of turbidity and color present in water. It also indicates such auxiliary facts regarding pH adjustments and the necessity for the supplemental use of activated carbon. The laboratory-scale unit of the Flocculation test unit consists of 6 Nos. of Glass Flocculating vessels. These are provided on a translucent base which is illuminated from the bottom by a fluorescent lamp, fitted with a reflector. Each vessel is provided with a separate stirrer. A Paddle type SS Impeller is fixed on The stirrer shaft and the speed of the impellers can be regulated with the provided speed controller. All stirrers are driven with one variable speed motor. This paddle assembly can be easily removed for cleaning purposes.
Detailed Operation & Maintenance Manual is provided along with the trainer.
