Silica quartz used for water filtration is a filtering medium widely used in the field of water treatment, which helps to remove suspended solids, colors, odors, bacteria, etc. in water.

Besides, the size of silica quartz should match the size of the particles to be filtered. 

If the size of silica quartz  is too small, it may not be able to effectively filter large particles; If the size is too large, it may block the filter and affect the filtering effect.

What's more, when designing a water treatment system. 

It is necessary to consider factors such as filtration efficiency and pressure loss of filter media with different sizes of silica particles to ensure the normal operation of the system.
