Wastewater low-temperature evaporation equipment produced by regular manufacturers must possess complete environmental protection, quality, and compliance qualifications to pass environmental impact assessment, acceptance inspection, and ensure long-term stable operation. The following is a list of core qualifications and key selection points:

## I. Essential Basic Qualifications (Common in China)

1. Quality System Certification (Mandatory Inspection)

- ISO 9001 Quality Management System Certification: Standardized production processes and controllable quality.

- ISO 14001 Environmental Management System Certification: Compliance with corporate environmental management.

- ISO 45001 Occupational Health and Safety Management System Certification: Compliance with safety regulations.

2. Environmental Protection and Product Certification (Core)

- Environmental Protection Equipment Certification / Environmental Protection Product Certification: Proves that the equipment meets environmental treatment requirements.

- Energy-saving Product Certification (GB 30253): Mandatory for heat pump / MVR type equipment, proving compliance with energy efficiency standards.

- Water Treatment Equipment Manufacturing Qualification: Such as compliance certificate for *Technical Conditions for Water Treatment Equipment Manufacturing* (JB 2932).

- Special Equipment Qualification (Pressure Vessels / Vacuum Equipment): For equipment involving pressure vessels or vacuum tanks, a Pressure Vessel Manufacturing License (Grade D1/D2) and Special Equipment Type Test Report are required.

3. Industry-Specific Qualifications (Selected According to Scenarios)

- GMP Food / Pharmaceutical Grade Equipment Certification: Mandatory for pharmaceutical and food industries.

- Explosion-proof Certification (Ex): Mandatory for flammable and explosive scenarios such as chemical and pharmaceutical industries.

- EU CE Certification: Mandatory for export or foreign-funded projects.

4. Enterprise Strength Qualifications (Bonus Items)

- National High-Tech Enterprise
