APPLICATION
ENGINEERED FOR RED & WHITE SIDE ALUMINA PROCESSES
Can be used to monitor liquor-phase density in areas such as the Digestion Blow Off (DBO)/Last Flash Tank and precipitation feed.
Install the sensor directly in the main process pipe (no need for traditional recirculation lines).
Ideal for low flow velocities of 1.8m/sec.


ALUMINA BAYER'S PROCESS
The
AL-CARK®
Advantage
Reduces Caustic Soda consumption by maintaining optimal NaOH concentration.
Stable Precipitation Feed Density improves yield & minimises fines.
Cuts Lab Sampling Costs – Eliminates frequent offline density checks.
Drift-free measurement corresponding typically to within 0.5 g/l Soda.
No Calibration required.
RELATED PRODUCT
In Bayers Process Applications where the A/C ratio or molar ratio varies significantly, we recommend using the ALCARK® in-line refractometer sensor in conjunction with a Conductivity Device: AL-DCIK® to assist in complete concentration control.
