Elektrolyse Reaktion

Membrane electrolysis

The continuous dosing of highly effective chlorine in the form of hypochlorous acid ensures that the right amount of active chlorine is in the water at all times. This means that even people with sensitive skin can bathe in the water. Eye and skin irritation as well as unpleasant swimming pool odours are avoided.

The cost of producing active chlorine with an electrolysis system is significantly lower than the price of purchasing commercially available chlorine bleach. The need for pH-regulating care products is drastically reduced. This reduces the risk of accidents. Thanks to the modern membrane cell technology, the bathing water is not salinised.

The ECO-a system

Our new ECO-a series offers many advantages of our previous systems combined with new developments and improvements for use in swimming pools. In particular, the advantage of being able to position the salt and product tank independently of the system enables maximum user-friendliness in the planning and operation of your swimming pool.

The integrated control system regulates the output and monitors all operating parameters. Hydrogen produced during the process is separated by a degassing tank and must be discharged to the outside. The fresh hypochlorite is fed into the product tank without an additional pump and can be dosed from there as required.

How does salt electrolysis work?

The chemical process takes place in the specially designed electrolysis cell. The electric current causes a reaction in the salt solution, producing free chlorine. Inside the reaction chamber, the water is cleaned and disinfected in a hygienically perfect manner. This causes bacteria, algae and other microorganisms to be erased. The system and its performance are specifically designed for the spectrum of your needs.

Salt electrolysis or chlorine?

Compared to traditional chlorination, salt electrolysis offers a more pleasant effect on the skin and eyes. The direct disinfection of the water in the system does not produce any unwanted reaction byproducts. In conjunction with modern measurement and control technology, optimal water quality is achieved that is perfectly tailored to the pool – with minimal use of additional pool chemicals. Salt electrolysis offers an effective solution, especially in indoor swimming pools, where the smell of chlorine is often perceived as annoying. The unpleasant smell of swimming pools, caused by chloramines in conjunction with substances introduced by bathers, is avoided by disinfection in the system. Thanks to this process, you can now enjoy an odor-free and skin-friendly bathing experience. Although the initial installation cost for a salt electrolysis system may be higher, long-term savings come from the reduced need for additional chemicals and ease of maintenance.

What types of salt electrolysis units are there?

Membrane electrolysis: The electrolysis cell is separated by a specially developed membrane. The chlorine splits off at the anode and is inoculated into the pool in its purest form. Depending on the type of system, the electrolysis output can be regulated. Any design is conceivable, from small systems for private users to systems for public facilities.

Tube-cell electrolysis: Tubular cell electrolysis saves on transport routes and expensive pool chemicals by producing the required chlorine on site from commercially available salt. The fresh sodium hypochlorite produced in the system is stored directly in the product tank without an additional pump, from where it can be dosed as required.

Compact flow-through cells: These systems are often designed for smaller pools or spas and integrate the electrolytic cell into a compact housing. They are easy to install and require less space, but the performance spectrum of such a system is limited.

What is salt electrolysis?

Salt electrolysis is a method of disinfecting water and is often used in swimming pools and whirlpools, but also in many other applications where the highest demands are placed on water quality. In salt electrolysis, chlorine is produced from the salt dissolved in the water; through an electrolysis process, which then disinfects the water.
