Purchasing Guide

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

  • For procurement needs that require the use of oily wastewater treatment, it is recommended to prioritize confirming key technical parameters such as oil-water separation efficiency and treatment capacity of the treatment equipment to ensure compatibility with production scale. For example, the catering industry needs to pay attention to the adaptability of high oil load scenarios.
  • 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 solutions in high incidence areas of oily wastewater such as petrochemicals or mechanical processing.
  • In different scenarios such as metal processing or food industry, the corrosion resistance and automation level of oily wastewater treatment equipment may become key considerations, and procurement standards need to be adjusted according to actual differences in wastewater composition.
  • When purchasing oily wastewater treatment systems, it is recommended to evaluate the supplier's actual application experience based on industry case data, such as reviewing their project history in specific fields such as automotive manufacturing or ship maintenance.

Knowledge Base

Q

When choosing an integrated oily wastewater treatment equipment, multiple key factors need to be considered to ensure the effectiveness and economy of the equipment.
