Purchasing Guide

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

  • For procurement requirements that require the use of internal flow grilles, it is recommended to prioritize confirming key technical parameters such as gap width and treatment flow rate to ensure compatibility with sewage treatment systems.
  • In municipal sewage treatment or industrial wastewater pretreatment scenarios, the corrosion resistance and structural strength of the internal inlet grille are important factors affecting long-term operational stability.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support to screen for suitable partners.
  • For high suspended solids interception scenarios, it is recommended to evaluate the operating efficiency of the internal inflow grille under different load conditions by combining the rake tooth material and driving method.
