1. Filter material particle size: The particle size of quartz sand needs to be selected according to different water treatment processes and needs. Generally speaking, the slower the filtration speed and the finer the particle size, the better the filtration effect.
2. Purity of quartz sand: The purity of quartz sand has a significant impact on the filtration effect. High purity quartz sand has better filtration effect, more uniform particles, and stronger corrosion resistance.
3. Compressive performance: The compressive performance of quartz sand is also one of the factors to consider when selecting filters. Quartz sand needs to withstand water pressure and impact during backwashing, so choosing quartz sand with good compressive performance can ensure the service life of the filter.
4. Corrosion resistance: According to different water quality, quartz sand with good corrosion resistance needs to be selected to avoid corrosion deformation of quartz sand and affect the filtration effect.
5. Cost: The cost of quartz sand is also a factor to consider when selecting filters. We need to choose quartz sand that is cost-effective and cost-effective.
