Purchasing Guide

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

  • For procurement requirements that require the use of buried oil-water separators, it is recommended to screen based on key technical parameters such as processing capacity, separation efficiency, and corrosion resistance to ensure that the equipment can meet the actual working conditions.
  • In scenarios such as catering, food processing, or industrial wastewater treatment, the installation space and drainage method of buried oil-water separators need to be planned in advance to avoid increased renovation costs in the later stages.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to reduce procurement risks.
  • When purchasing buried oil-water separators, it is usually necessary to pay special attention to the material thickness and anti leakage design of the equipment, which directly affect the stability and maintenance frequency of long-term use.
