The replacement of the membrane depends on the water quality source and the frequency of use. Regularly monitor the amount of water produced and the Conductivity (TDS) of your osmotic water to determine the ideal time for change. Preventive maintenance preserves the quality of filtering and the longevity of the system.
For optimal performance, replace also Pre-filters sediment and activated carbon At regular intervals before installing a new membrane. Use only cold water at room temperature and avoid overpressures greater than 4 bar.
💡 Original product ARKA Myaqua® - certified German quality. Registered trademark (DE302021228034.6). To keep in a dry place and sheltered from heat.
The membrane ARKA Myaqua 400 is the heart of the reverse osmosis system ARKA Myaqua® 400. It eliminates up to 99% of harmful substances, salts, heavy metals, pesticides and tap water bacteria, ensuring pure water for marine aquarium and freshwater.
The replacement frequency depends on the quality of the source water and the use. In general, it is advisable to regularly check the conductivity (TDS) and the production of osmosis water: if the values increase or the flow drop, the membrane must be replaced.
The maximum flow rate is 0.27 l / min, or about 16 liters per hour. This efficiency may vary depending on the inlet pressure (1 to 4 bar) and the water temperature (5 ° C to 45 ° C).
Yes, the membrane ARKA Myaqua 400 is suitable for sea water aquariums and freshwater aquariums. It provides osmosis water of very high purity, essential for the preparation of new water or the dilution of marine salts.
It is composed of a reinforced nonwoven fabric of polyester and ultrafine pores (0.0001 micron). Under pressure, the water crosses the membrane while the pollutants and impurities are rejected towards the evacuation, producing a pure water and without residues.
The water pressure, temperature and quality of source water have a direct impact on the performance and life of the membrane. Too low pressure or very limestone water can reduce filtration efficiency.
