The efficiency of the reverse osmosis equipment are greatly influenced by the state of the membranes, therefore their protection is a very important step in operating the equipment.

As a membrane protection agent, we recommend dosing it continuously to the water to be treated. We also offer solutions for contamination and blockage of the membrane: the wide range of our membrane cleaning products effectively loosen and remove biological as well as mineral deposits.

In case of periodical cleaning and continuous chemical dosage, the equipment may be operated profitably, and its capacity may be sustained at its nominal value, decreasing the costs of periodic maintenance.

Continuous protection:

A primary task is therefore the binding of the chlorine content of the mains water before releasing the water to be treated on the membrane, as the free active chlorine in the water significantly deteriorates the membrane material. In low-capacity systems, this can be practically solved by activated carbon filtration, and by adding chlorine binding chemicals in larger systems.

The hardness of the treated water significantly influences the condition of the membrane. To prevent limescale depositions forming on the material of the membrane, the addition of pre-softeners, or in case of equipment of greater performance (above 500 l/h), antiscaling agents is recommended. Dinax Membrantreat F, the additive recommended by our company also prevents the formation of silicate deposits besides limescale on the surface of the membrane, whose removal would otherwise require special solutions.

In pre-treated, dechlorinated water however, microbiological organisms may appear that stick into the pores of the membrane during reverse osmosis treatment and propagate there, thereby significantly reducing the performance of the former over time. The formation of contamination can be avoided by dosing biocidal agents, for whose selection it is an important aspect that they do not harm the sensitive material of the membrane, and have no oxidative properties. Its continuous dosage significantly helps reduce operational downtime due to cleaning maintenance.

All of the agents mentioned in the topic are recommended to be dosed proportionately to the water quantity by the NAVIDOS quantity-proportional chemical dosing device into the feedwater line.
