Recently, at API Heat Transfer (Suzhou) Co Ltd in SIP High-end Manufacturing and International Trade Zone, an old cleaning unit that had used trichloroethylene was safely dismantled and removed from the production line under the supervision and guidance of local environmental law enforcement officers. This marked the successful conclusion of the company’s over-one-year cleaning process upgrading for environmental protection.
The local environmental law enforcement department followed the whole process of the upgrading project, discussing with the company solutions for pollution control, providing suggestions and assistance for the design and implementation of the project, and ensuring safe disposal of the old equipment.
The new ultrasonic cleaning line is expected to help cut VOC (volatile organic chemical) emissions by 80% annually, and a supporting wastewater treatment system can reduce hazardous waste by about 30 tons per year, slashing disposal costs by 35%.
