The JBK Series Frame Mixer is a large-scale, low-speed agitation system engineered for flocculation and coagulation stages in water and wastewater treatment facilities. Featuring an oversized frame-type impeller paired with reliable cycloidal pinwheel or gear reducer, this system delivers ultra-low rotation speeds of 31 to 43 rpm for optimal floc formation.

Key Applications
Flocculation & Floc Cultivation: During municipal water treatment, the massive frame impeller (up to 98.4 inches wide) slowly sweeps the entire basin, providing gentle micro-turbulence that encourages suspended particles to agglomerate into large, dense flocs.
High-Viscosity Sludge Homogenization: The extensive surface area of the frame structure forces bulk fluid movement in high-concentration sludge tanks or viscous chemical dosing basins, preventing heavy concentrates from accumulating on tank floors and walls.
Frequently Asked Questions
Why is an ultra-low speed of 31-43 rpm mandatory for flocculation processes?
During flocculation, micro-particles agglomerate into delicate "flocs." High rotation speeds create shear forces that destroy these newly formed structures. The JBK Series' low-speed configuration balances uniform chemical dispersion with the critical requirement of protecting floc integrity.
How does the Frame Mixer eliminate dead zones near the tank walls?
Unlike conventional small impellers that generate localized jets, the JBK Series frame impeller is custom-sized to match the internal diameter of mixing basins (up to 2500 mm / 98.4 inches). As it rotates, it physically sweeps nearly the entire cross-section of the tank, mechanically eliminating mixing dead zones along perimeter walls.
