A very important filtration device in pure water equipment - quartz sand, can be said to play a very important role in the entire filtration process, but it needs to be replaced regularly when it comes into contact with impurities every day. How long is it good to replace it?

Quartz sand is a common filtering material in sewage treatment, and in pure water equipment, filtering materials belong to consumables. Due to poor control of backwash pressure and natural aging, filtering materials may experience material leakage and delamination, which leads to loss of filtering materials. Due to some unavoidable reasons, we need to replace the filtering materials on time.

The method of clarifying the application cycle time of quartz sand filtration materials is relatively simple. When it was found that the water in the quartz sand biofilter was turbid and suspended solids were lifted after filtration, some quartz sand filtering materials were filtered out after backwashing, and compared with the quartz sand filtering materials before installation. If the specifications and models of various quartz sand filtering materials gradually decrease, that is, the application cycle time of quartz sand filtering materials has arrived, it is necessary to immediately replace the quartz sand filtering materials to ensure that the water output meets the standard.

In general, if the pressure difference between the inlet and outlet water after backwashing is not significant, replacement can be omitted. However, it cannot be generalized. It is suggested that the general quartz sand used for wastewater treatment will not work for 3-5 years. Even if the quartz sand is polluted by the environment, it will not be effective. In wastewater treatment, sludge can carry out aerobic or anaerobic respiration to dissolve air pollutants in wastewater. Specially made quartz sand filter material: used in pure water treatment. In quartz sand filters, they usually need to be replaced every 2-3 years. After being polluted by the environment, the air pollutants will wrap around the quartz sand and it can no longer have very good filtering effects. Only replacement is necessary.

Quartz sand filtration material is the most commonly used filtration system, with a wide range of applications. It can be used for domestic water and industrial production of tap water, as well as various types of general fast biological filters and wastewater filtration devices, purified water treatment filters, multi substance filtration devices, and integrated water purifiers.

Whether it is industrial water or mineral water filtration solutions, many of them use quartz sand filtration substances. The service life and replacement cycle time of quartz sand filter materials in sewage treatment are also caused by different road surfaces, water bodies, flowing water, drainage pipeline rates, and daily emissions, which immediately endanger the operation cycle time of quartz sand filter materials. Quartz sand filter material, as a type of water treatment filter material, has gone through more than 2 years of work. Due to the lack of immediate backwashing by the enterprise, the water itself is not clean, resulting in the quartz sand filter material not working properly in the water and being stuck by unclean things, leading to breakage. In that way, the filtering rate will be immediately compromised, causing particularly slow water output and inability to provide normal power supply. Therefore, the quartz sand filter material should be replaced immediately.
