The replacement cycle of manganese sand filter media is generally 3-5 years, but it needs to be adjusted dynamically according to water quality, usage conditions and maintenance conditions.
Core influencing factors
Water quality conditions
When the iron and manganese concentration is high, the filter media is consumed quickly and the replacement cycle is shortened to 3-5 years; when the concentration is low, it may be extended to 10 years. For example, groundwater with high iron content will accelerate the consumption of manganese sand active filter membrane, while the active filter membrane formed on the surface of the filter media under low concentration water quality can still maintain catalytic effect.
The content of impurities such as silt and pH value in the water will also affect the life of the filter media.
Use conditions
Excessive filtration rate and filtration pressure will accelerate the wear of the filter media and shorten the replacement cycle; reasonable aeration process can improve the efficiency of iron and manganese removal and indirectly extend the service life.
Maintenance method
Regular backwashing can remove blockages on the surface of the filter media, maintain permeability and catalytic activity, and is the key to extending the life.
If the filter media is hardened or broken due to long-term lack of maintenance, it needs to be replaced in advance.
