Product Description: Model 1922 Digital Flocculator/Jar Test Apparatus (EI-DVI Brand):
Overview: Precision Flocculation Analysis:
The Flocculator/Jar Test Apparatus, Model 1922, is a critical laboratory instrument specifically engineered for performing flocculation (jar) tests on water and effluent samples. This unit accurately replicates the crucial coagulation and flocculation processes used in full-scale water and wastewater treatment plants. It allows operators and researchers to determine the optimum chemical dosing, such as alum, required for effective treatment. The Model 1922 is configured to accept two test samples simultaneously.
Digital Control and Operational Efficiency:
The Model 1922 is equipped with advanced digital controls designed for highly reproducible testing:
• Variable Speed Control: A digital display clearly indicates the speed of the rotational stainless steel paddles, which can be accurately varied across a range of 10 to 300 RPM.
• Integrated Digital Timer: The digital timer can be set to count down from 1 to 99 minutes. Once the countdown is complete, the stirring paddles automatically stop, and an audible alert sounds. The timer then begins counting up in minutes to facilitate precise measurement of the settling time.
• Pre-set Programs: Two memory pre-set programs are included, allowing routine speed and time parameters to be easily input, stored, and recalled at any time by simply pressing a single button.
• User Interface: The apparatus features an intuitive touch-sensitive keypad that is totally flat, ensuring easy operation and cleaning. The speed is regulated by an electronic speed regulator, providing stable control.
Visibility and Durable Construction:
The design of the Model 1922 prioritizes ease of observation and durability in the laboratory environment:
• Optimized Sample Viewing: Built-in illumination is provided by white LEDs placed beneath a diffuse acrylic plastic plate at the base. This arrangement delivers effective, glare-free, cold light illumination, helping users accurately observe the formation and settling of floc samples.
• Robust Materials: The unit is supplied with stainless steel stirring paddles and rods, which offer strong resistance to chemical corrosion during testing.
• Adjustable Height: The stainless steel paddles feature adjustable spaces or locking knobs, permitting easy adjustment of the paddle depth within the test beaker to meet specific test requirements without disturbing other components.
Key Applications:
This apparatus is indispensable for water quality management and chemical treatment optimization across various sectors:
• Water Treatment Plants: Used for correctly estimating the optimal dosage of coagulants, such as alum.
• Sewage and Effluent Treatment Plants (STP/ETP): Simulates flocculation and sedimentation processes to calculate total chemical requirements.
• Research and Development: Essential for coagulation studies, evaluating coagulant performance, and water treatment research in R&D laboratories and universities.
• Industrial Water Management: Supports water quality control in facilities managing their own water supply or wastewater treatment processes.
