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.

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.
