Dry Flocculation Tester

Meet the standard:

ASTM D2035

Product Introduction:

Flocculation is a process used in many industries (water treatment, mining, paper manufacturing, chemical processing) to aggregate small particles into larger, more easily separable flocs. Often, flocculant chemicals are supplied in dry powder or granular form, or the material being flocculated starts as a dry powder that must first be dispersed in a liquid. A Dry Flocculation Tester provides a controlled environment to study the steps involved when a dry material interacts with a liquid to form floccules.

Such a tester would typically facilitate the controlled addition of a dry powder (either the material to be flocculated or a dry flocculant) into a liquid. This might involve a mechanism to ensure consistent powder feed rate or rapid, complete dispersion. Following the initial dispersion phase (often with high-speed stirring), the mixing conditions are changed (typically to slower stirring speeds) to promote the formation of floccules.

The equipment is used in laboratories for:

Evaluating the dispersibility and flocculability of dry powders in specific liquids.

Testing the performance and optimizing the dosage of dry flocculant chemicals.

Comparing the flocculation behavior of materials under different conditions (e.g., stirring speed, temperature, liquid composition).

Research and development of new flocculants or materials with improved flocculation properties.

Quality control of dry powders and flocculants.

Product Advantages:

Allows controlled evaluation of flocculation processes involving dry particulate materials or dry flocculants.

Helps optimize the dispersion stage, which is critical for effective flocculation from dry materials.

Provides insights into floccule formation kinetics and characteristics.

Useful for comparing the performance of different dry flocculants or the flocculability of various powders.

Supports research, development, and quality control in industries utilizing flocculation.

Product Features:

Base unit with multiple positions for holding test vessels (e.g., beakers or cylinders), often arranged linearly for easy observation.

Stirring mechanism with independently controllable stirring speed for each position, capable of both high speeds for initial dispersion and low speeds for gentle flocculation.

Digital display and control for setting and monitoring stirring speeds and test duration.

Timer for controlling different mixing phases (e.g., rapid mix time, slow mix time).

System for controlled addition of dry powder or dry flocculant to the liquid in the test vessels. This might be a simple manual addition point or an automated dispenser with a controlled feed rate.

Illumination system (e.g., backlighting) to facilitate visual observation of particle dispersion, floccule formation, and settling.

(Optional) Temperature control for the liquid in the test vessels.

(Optional) Integrated turbidity meter or particle size analyzer for quantitative monitoring of the flocculation process.
