Testing water treatment systems for reducing scale formation - by pumping the water through a capillary in temp. controlled medium and observing blockage formation

摘要

A means for testing the efficiency of chemical, physical-chemical or physical methods for hindering boiler scale-forming pptes. comprises pumping the soln. to be tested or the treated water sample through a capillary which is immersed in a temperature-controlled medium. USE/ADVANTAGE - The test is easy to carry out and provides a quantitative value for the efficiency of any particular system by measuring the time taken from the start of the test to blockage of the capillary as evidenced by a rise in press. in the feed to the capillary. The system can be used e.g. to test the efficiency of treatments for boiler feed waters, domestic hot water systems, etc.
