Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of sewage equipment, it is recommended to prioritize checking key technical parameters such as treatment flow rate and corrosion resistance level to ensure compatibility with the characteristics of the factory wastewater. In industrial scenarios, additional attention should be paid to explosion-proof design.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually have more stable equipment adaptability in sub sectors such as chemical and municipal industries.
  • For high organic wastewater scenarios such as food processing, it is recommended to choose sewage equipment with pre-treatment modules and confirm whether there is similar industry application data in the cases provided by the supplier.
  • When purchasing sewage equipment, it is necessary to combine long-term operation and maintenance cost evaluation, such as energy consumption indicators and replacement cycles of vulnerable parts. Such information can be obtained for reference through industry platform statistics or supplier historical cooperation records.
