Water treatment with salt electrolysis

Electrolysis in pool water is a splitting of NaCl, or salt. The advantage of salt electrolysis is that the salt electrode automatically produces chlorine, which disinfects your pool water. This means that you do not have to store hazardous chemicals or manually add chlorine to the pool.

Measuring and correcting pH and chlorine

To ensure clean and safe water, the Beni Twin automatically regulates the pH (acidity) of the water between 7.2-7.6 and the chlorine content between 0.5 and 1.5 ppm

The pH is continuously measured with a pH probe.

&Chlorine is measured with a Redox probe for Salt electrolysis. In general, a Redox of 700mV corresponds to 1 ppm chlorine. The redox sensor is covered with a protective layer of gold. If the pH is too high, the system will automatically dose acid to correct the pH via a peristaltic pump. For a swimming pool of 100 m³, the system will dose approximately 100 ml of acid per day.automatically dose acid to correct the pH via a peristaltic pump. For a 50 m³ pool, you will need approximately 15 to 30 cl of 15% sulphuric acid (= one glass) per day.

To adjust the chlorine content, the salt electrolysis will automatically produce chlorine (or bleach) via a salt electrolysis cell.For a 50 m³ pool, you will need a Salt electrolysis device that produces at least 15 g of chlorine per hour. For salt electrolysis to work, salt must first be added to the pool. This salt is then converted into chlorine by the electrolysis cell. After the chlorine reacts with algae, bacteria, etc., it is converted back into salt. An earthing must also be connected and it is necessary to choose between "low-salt" or "lt;a href="/pages/rapid-search-results?q=HS+salt electrolysis" title="/pages/rapid-search-results?q=HS+salt electrolysis">salt-rich " with 2 or 4 g/litre of salt (NaCl) dissolved in the pool water (100 or 200 kg for a 50 m³ pool). The effect of "low" and "high" salt is identical, only the feel of the water changes.

Plug & Play - water treatment installation

Both the Beni Duo and the Beni Duo Wifi are fully pre-assembled on a plate. All connections and pipes are already in place, so you don't have to connect anything yourself. Simply place the panel on the return pipe to the pool in a 50 mm pipe. This can be done using the supplied 50 mm rubber straight connections. A bypass is not required. All accessories for installation and use (probes, calibration fluid, manual, etc.) are included. The normal operating conditions (pH 7.2-7.6, Redox > 700mV) are already pre-programmed into the device.

Wi-Fi or display?

The Beni Duo is available in both Wifi version as Display version .

The Wifi version works via the "WiFiPOOL-app ". The advantage of this solution is that you can literally verify and adjust your water quality anywhere in the world. Using the WiFiPOOL-app and equipment, you can also measure and adjust other parameters of your pool (temperature, level, flow).The Display version is one of the simplest water treatment devices on the market. You can read the pH and Redox (chlorine) levels on the display. The handy menu allows you to change the preset parameters (language selection, pH and redox setpoint, etc.). Both devices work in the same way: they continuously monitor the pH and Redox (Chlorine). As soon as one of them needs to be adjusted, the Salt electrolysis and/or pH pump is activated.
