• Applicable pH Range: 5-9
• Regeneration (Phosphate): 1-5% NaOH solution slow washing/soaking for 80min
• Operating Temperature (℃): 5-40

• During use, repeated loading and unloading of the filter media should be avoided as much as possible to prevent uneven filter media bed leading to channeling.

• For short-term shutdown
  the filter media should be disinfected, cleaned thoroughly and then soaked in clean water.

• For long-term shutdown or when the room temperature is lower than 5℃ in winter, the filter media should be soaked in 1-5% sodium hydroxide aqueous solution to prevent bacterial growth and freezing.
• The water entering the filter tank must undergo necessary pretreatment filtration to remove solid impurities, reduce SS (Suspended Solids) and prevent pore blockage which affects the adsorption effect of the filter media.

It should be stored in a cool and dark place. Prevent the filter media from freezing or overheating: the general storage environment temperature of the filter media is 5 ~ 40℃. The storage time of unused filter media should not be too long, generally not exceeding 1 year. If the storage period is exceeded, it can be used continuously after passing the re-inspection.
