How long is the replacement time of several commonly used filters?

How much do you know about the replacement time of several commonly used water treatment filters? Let's introduce them below.

Anthracite filter material:

The replacement cycle of anthracite filter material is generally 1-2 years. The replacement cycle with low backwash intensity can be shortened slightly, and the replacement cycle with high backwash intensity can be slightly extended.

Quartz sand filter material:

The replacement cycle of ordinary quartz sand is generally: 3-5 years or more. If the quartz sand itself is not contaminated or compacted, it does not need to be replaced, and only the loss of quartz sand needs to be supplemented every year.

The replacement cycle of the refined quartz sand filter material is slightly shorter, usually 2-3 years, and the quartz sand needs to be replaced when it is compacted or attached to pollutants.

Manganese sand filter material:

The replacement period of manganese sand filter material is 1-2 years. If the manganese dioxide content is greater than 35%, the service period can be extended appropriately.

Sponge iron filter material:

The replacement cycle of the sponge iron filter material can be determined according to the filter material and water quality. Generally, it is enough to make up the loss in 3-6 months.

Activated carbon:

The replacement cycle of activated carbon is related to the type and quality of the activated carbon itself and is also directly related to the water quality conditions being treated. Therefore, the replacement cycle of activated carbon is relatively wide, but the replacement cycle of activated carbon is generally one year.

Cobblestone filter material:

The cobblestone filter material acts as a supporting layer. If there is a backwashing device, the replacement cycle can be extended. There is no problem in 3-6 years, and the loss should be supplemented regularly.
