Purchasing Guide

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

  • For procurement requirements that require sewage treatment, it is recommended to prioritize confirming key technical parameters such as treatment capacity and COD removal rate. In industrial scenarios, additional attention should be paid to heavy metal treatment capacity.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, suppliers with petrochemical industry cases need to be screened for chemical wastewater treatment.
  • Municipal sewage treatment projects usually need to consider the long-term operational stability of equipment, and it is recommended to choose modular or integrated technical solutions based on the daily treatment scale.
  • When purchasing decentralized rural sewage treatment equipment, in addition to technical parameters, it is recommended to pay attention to the supplier's operational response capability and energy consumption data in remote areas.
