Product description

DFR-05: Dewatering and retention

Develop and characterize retention agents and drainage aids the market demands
Understand chemical reactions in the lab and onsite
Apply the correct additive in a process environment
Optimize chemical dosages for better operation and cost saving
Accurate automated consistency results for fiber stock and pigments (ash) replacing time-consuming manual determination

The lab device MütekTM DFR-05 Drainage Freeness Retention simulates the retention and drainage conditions prevailing in a paper machine immediately before and during sheet forming. This enables a systematical assessment of chemical influences.

Chemical addition is fully automatic via an integrated dosing module. The optionally available RET-20 Lab Sensor directly measures the filtrate consistency, making a time consuming manual determination of stock and ash consistencies superfluous.

The drainage behavior is characterized by gravimetry of the filtrate volume. Besides, the Schopper-Riegler freeness can be determined from which the Canadian Standard Freeness (CSF) may be calculated applying a correlation
