Purchasing Guide

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

  • When selecting industrial wastewater treatment projects for supply, it is recommended that companies match treatment process parameters based on the type of wastewater (such as electroplating, printing and dyeing, or chemical wastewater), such as COD removal rate, daily treatment capacity, and other key indicators.
  • For special scenarios such as high salt or heavy metal wastewater, priority should be given to the industry performance of suppliers in similar projects, and a comprehensive evaluation should be conducted based on the activity level and business qualifications of the enterprise.
  • When selecting suppliers, reference can be made to product compatibility and industry data support, such as whether there are case studies in specific fields such as petrochemicals and pharmaceuticals, to ensure technical adaptability.
  • The design of industrial wastewater treatment projects should be combined with the factory space and discharge standards. It is recommended to screen suppliers with stable operating records through platform statistical information.

Knowledge Base

Q

Do you know the steps involved in wastewater treatment engineering? I'll tell you. 1、 Confirm the source of pollution, water quantity, and water quality to determine the source of toxic and harmful substances in sewage, which link and factor are causing it; The water quality situation also needs to be determined, and it is recommended to continuously and regularly take samples for testing in order to obtain a scientific understanding of the water quality situation. 2、 Environmental impact assessment is being conducted in the early stage of sewage discharge standards

Q

A large amount of high salt wastewater is generated during the production process of an industrial enterprise, with high salt content and large pH fluctuations (7.9-9.8), containing a small amount of organic matter and microorganisms. Traditional disinfection processes cannot adapt to high salt and high pH environments, resulting in poor disinfection effects and easy equipment corrosion problems. To solve the problem of disinfection of high salt wastewater, enterprises introduce targeted water treatment sterilization ultraviolet rays
