- Electrolysis System


Output of 100 – 300 g ultra-pure hypochlorous acid per hour. Efficient production of DulcoLyt 400 (ECA water) with an exceptionally low chloride and chlorate content. Maximum protection against corrosion and very good cost efficiency because of low chloride.

Innovative disinfection. Your advantage: No corrosion due to low chloride content.

Electrolysis systems of the type DULCO Lyse generate ultra-pure hypochlorous acid in a vacuum process. A saturated solution of sodium chloride is produced in a salt dissolving tank, included in the scope of delivery, and this solution is then electrolysed in a diaphragm cell. Chloride-free sodium hydroxide and hydrogen are produced in the cathode chamber, while ultra-pure chlorine gas and dilute residual brine are produced in the anode chamber, separated by the diaphragm from the anode chamber. The active chlorine produced is immediately separated from the residual brine and dissolved as hypochlorous acid. The sodium hydroxide is temporarily stored and added to hypochlorous acid through a metering pump. The result is a neutral, highly effective and extremely low-chloride and low-chlorate disinfection solution, temporarily stored in the product tank until metered through separate metering stations. The hydrogen produced is diluted with fresh air through an ATEX-approved fan and discharged safely. The diluted residual brine is fully discarded. To do so, the diluted brine is strongly diluted with softened water, neutralised by the addition of sodium hydroxide and disposed of in the sewer. Any residual chloride and chlorate is thus disposed of and is not mixed with the process water. DULCO Lyse systems can thus be compared with pure chlorine gas in terms of their oxidation strength and chloride and chlorate content in the process water. The salt dissolving water comes from a softening system integrated in the DULCO Lyse system, thereby preventing the formation of lime deposits and ensuring the long service life of the electrolytic cell.
