A B S T R A C T A METHOD AND APPARATUS FOR TESTING THE EFFECTIVENESS OF CHEMICALS SUCH AS SCALE INHIBITORS OR SCALE REMOVERS A method for testing the effectiveness and performance of chemicals in a scale-forming liquid, in particular scale inhibitors, comprising the steps of supplying the liquid through a test circuit, measuring and recording continuously the inlet pressure to a test circuit during a redetermined time, adding subsequently the che- micals to be tested to the liquid, and at each addition measuring and recording continuously the pressure to the test circuit. A method for testing chemicals such as scale removers in a scale-forming liquid, comprising the steps of supplying the liquid through a test circuit and after scale has been deposited from the liquid, adding suitable chemicals to the test circuit and con- tinuously measuring and recording the pressure decrease in the test circuit. An apparatus for carrying out the above-mentioned methods.
