Preparation for handling a portion of key equipment including sand filters, carbon filters, and softeners. After some time in use, sand and carbon filters accumulate fine sand, residues, collagen fibers, and other large particles on their surfaces. The complete industrial wastewater treatment equipment should undergo backwashing of the sand and carbon filters every 15-30 days to remove the residues on the sand and carbon layers, thereby enhancing the filtration efficiency. The软化ers function primarily by using the principle of cation exchange to reduce water hardness; thus, as usage time increases, the softening capacity of the styrene-divinylbenzene (SDB) resin gradually diminishes, necessitating regeneration with NaCl. Industrial Wastewater Treatment Tank: The process of purifying wastewater to meet the quality requirements for discharge into a water body or for reuse. Industrial wastewater treatment tanks are widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, catering, and are increasingly becoming part of everyday life for ordinary citizens.
