Membrane Electrolysis Systems CHLORINSITU® IV compact

The CHLORINSITU® IV compact range of electrolysis systems generates ultra-pure chlorine gas in a vacuum process that can immediately and safely be dissolved in water within the system as hypochlorous acid. Thanks to the membrane technology used, the sodium hydroxide generated can be collected separately and optionally used to adjust the ph value.

Electrolysis systems of the CHLORINSITU® IV compact type generate ultra-pure chlorine gas in a vacuum process. For this purpose, a saturated solution of sodium chloride is produced in a salt dissolving tank included with the delivery that is then electrolyzed in a membrane cell. Sodium hydroxide and hydrogen are produced in the cathode chamber and ultra-pure chlorine gas and scaled down residual brine are produced in the anode chamber separated by the membrane.

The resulting chlorine gas is suctioned off through an injector integrated in the system and dissolved in the water to be treated as hypo chloric acid. The generated hydrogen is discharged through a bleed line and the scaled down residual brine is disposed of. The sodium hydroxide is disposed of or optionally used with a metering pump integrated in the system to correct the pH of the water to be treated.

The salt dissolving water comes from a softener integrated in the plant, thereby preventing the formation of lime deposits and ensuring the long service life of the electrolytic cell. The microprocessor controller integrated in the system digitally indicates the actual feed rate and monitors all key functions. All operating and error messages are shown in plain text on the clearly arranged display. The feed rate can be controlled manually or externally.
