The JJ-4 Jar Testing Apparatus (or Flocculator) is a four-position laboratory device used to simulate and optimize water and wastewater treatment processes. It helps operators determine the exact dosage of coagulants (like alum) needed to remove impurities and form flocs.
Key Features
- Four Stirring Positions: Simultaneous testing of up to four 1000mL samples allows for quick comparison of different chemical dosages or varying mixing speeds.
- Speed Control: Typically offers variable speeds ranging between 0–2000 RPM (analog or digital), making it highly adaptable for both rapid-mix and slow-flocculation stages.
- Built-in Timer: Features a timer (0–120 minutes) to automate testing duration.
- Adjustable Paddles: Stainless steel stirring rods with adjustable spacers let you easily modify paddle depth.
- Backlight Illumination: Often includes a frosted base with an LED or fluorescent light, making it easier to visually observe the size, formation, and settling of flocs.
