Flocculator | Jar Test Apparatus for Water Treatment

A Flocculator is an essential laboratory and water-treatment instrument used for jar testing and flocculation studies in water and wastewater analysis. Accurate flocculation testing is critical for determining optimal chemical dosage and improving water quality. Hema Scientific Instruments, a trusted flocculator manufacturer in India, offers high-performance laboratory flocculators designed for precision, durability, and consistent results.

A flocculator, also known as a jar test apparatus, is a laboratory equipment used to simulate the coagulation and flocculation process in water treatment. It helps determine the correct dosage of coagulants by observing floc formation under controlled mixing conditions.


Hema Scientific Instruments manufactures digital flocculators with accurate speed control and uniform paddle movement to ensure reliable and repeatable test results.


A Flocculator, or Jar Test Apparatus, is a laboratory instrument used to study the coagulation and flocculation processes in water and wastewater treatment. It helps in determining the optimum coagulant dose, ensuring cost-effective and efficient removal of suspended impurities from water.


The Hema Scientific Flocculator is equipped with multiple stirring paddles, each operated at a uniform speed, to simulate the water treatment process under controlled laboratory conditions. This makes it ideal for both research and industrial testing applications.


● The Jar Test Apparatus evaluates the effectiveness of coagulation and flocculation processes in water treatment by simulating different conditions in multiple jars. It provides critical insights into the optimal chemical dosages and mixing parameters for achieving water quality.

● DIGITAL FLOCCULATOR (JAR TEST APPARTUS) has been specially designed for use in water treatment plants to correctly estimate the dosing of alum and such other coagulants for treatment of water & sewage. It provides identical test condition for all samples. Sulphate concentration & for measuring suspended matter and colloids general.  

● Gap between the walls is filled with special grade glass wool for proper insulation to avoid heat loss and thereby saving energy.
