The invention relates to a method for measuring the properties of a stack ( ) that viscous molten salt forms on the bottom of a soda recovery unit ( ) while black liquor is burned therein, and for measuring the corrosion of the materials of construction of the unit ( ) during the operation thereof. In the method, at least one sensor means ( ) is brought into contact with said stack ( ), this sensor means ( ) being electrically insulated from the soda recovery unit ( ). In the method, at least some electrochemical properties and the temperature of said stack ( ) are measured with this sensor means ( ). The data measured with this sensor means ( ) are fed to a measuring and data acquisition unit ( ), and said measuring and data acquisition unit ( ) is controlled by a control unit ( ).

Method for inhibition of growth of organisms on faces of constructions

The invention relates to a method for fixing an electrode arrangement to be used in the cathodic protection of concrete structures. In the method, an anode (20) is mounted in a framework (11) and the framework with its anodes is mounted on the concrete structure at a production plant or in the mounting step before the concreting step. The invention also relates to a fixing element (10) of the electrode arrangement to be used in the cathodic protection of concrete structures, which fixing element is comprised of an anode (20) and a framework (11), which framework (11) is provided with means (15) for fixing the element (10) to the concrete structure.

Method and a device for separating plastic particles from supensions

Plastic particles are separated from liquid mediums having the same distributed therethrough, in particular cellulose and paper fiber-containing mediums by electrolytic separation. The liquid medium is introduced into a container provided with an anode, a cathode and a reference electrode, with the plastic particles being separated from the liquid medium by controlling the potential of the anode and the cathode so that the potential of the anode is at most 2800 mV S.C.E., preferably +1200 to -300 mV S.C.E., and the potential of the cathode is at least -3500 mV S.C.E., preferably from +120 to -2100 mV S.C.E. The control of the potentials of the electrodes is effected to such ranges that gas production is selectively provided on the electrodes for cleaning thereof.
