Purchasing Guide

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

  • For procurement requirements that require the use of grid cleaning machines, it is recommended to prioritize confirming key technical parameters such as grid gap width, treatment flow rate, and material corrosion resistance to ensure compatibility with the actual operating conditions of the sewage treatment system.
  • Grid cleaning machines are widely used in municipal sewage plants, industrial wastewater treatment, and other scenarios. When purchasing, different models such as mechanical grids or rotary grids should be selected based on the type of interception material (such as fibers, solid particles).
  • 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.
  • In industrial high load wastewater treatment scenarios, it is recommended to choose a grid cleaning machine equipped with self-cleaning function and motor protection level of IP68 to reduce maintenance frequency and adapt to long-term operation in humid environments.
