Purchasing Guide

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

  • For procurement needs that require the use of buried oil separators, it is recommended to prioritize checking key technical parameters such as treatment capacity and oil-water separation efficiency to ensure that they match the wastewater discharge volume in scenarios such as catering and food processing.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable underground installation solutions.
  • When deploying in centralized drainage areas such as industrial parks or commercial complexes, it is necessary to consider the anti-corrosion materials and compressive strength of buried oil separators to adapt to long-term underground environmental use.
  • For different climatic conditions, the procurement in northern regions should pay attention to the anti freezing design of equipment, while coastal regions should focus on the specification parameters of salt spray corrosion resistance.
