DA-GEN Dryden Aqua Generator

How does the DA-GEN work?

For hydrolytic cleavage of water molecules to free radicals and production of the appropriate amount of free chlorine, we require water with a certain conductivity. Conductivity depends on the quantity of minerals in the water (TDS). The lower the conductivity, the more free radicals and other oxygen compounds and the fewer chlorine atoms are produced.

As we want to maximise the production of free radicals and minimise the production of chlorine for residual disinfection, we maintain water conductivity at the lowest possible level. With a conductivity of only 1.0 – 1.5 mS, the DA-GEN will produce enough free radicals as well as enough chlorine for residual disinfection.

Instead of using regular salt (NaCl), we recommend the use of the Dryden Aqua Activator based on Magnesium Chloride (MgCl₂). Our Activator not only raises conductivity to the desired level, it also improves filtration and assists in removal of phosphates from the water. Phosphates are required for algae and bacteria to feed. Only 1 kg of DA-GEN Activator per cubic metre of pool water volume is required. This small amount also ensures that chloride levels remain below 600ppm, the corrosion limit for V4A (316) stainless steel.

In order to properly manage this process, the DAGEN should always be used in conjunction with automated free chlorine and pH control. Only then, appropriate disinfection with a minimum of free chlorine of 0.1 mg/l can be assured.
