Environment-friendly water treatment system implemented in Tianjin, China


Reduce hazardous wastewater by

The wastewater generated from industrial enterprises are characterized by complex chemical composition and difficult in degradation, and the traditional treatment process is complex and costly.

Sustainability is a priority for the Hydro team in China and globally and working on a solution to prevent water waste was at the top of their agenda.

After detailed research, the site implemented a new system for wastewater treatment, meant to reduce hazardous wastewater, and do it at lower cost.

In a nutshell, the water goes through a series of treatment: filtering, pollutants separation, distillation and boiling.

This system is expected to reduce hazardous wastewater by 85% while reducing water consumption by 102 tons per year.

How does it work?


More technically: This new wastewater treatment process starts with filtering the wastewater in the Intermediate Bulk Container (IBC tank) through a three-phase separator to remove impurities such as sludge and oil slick. The wastewater then enters collection barrel and is processed through vacuum distillation wastewater treatment system. This system separates pollutants and water by utilizing the boiling point difference of substances by generating a negative pressure environment through steam compressor. The distilled water is then purified through ceramic membrane ultrafiltration.

Once purified, the water is returned to the workshop for reutilization, or discharged, after meeting the discharge standard of industrial effluent. The separated pollutants concentrate goes into a barrel and will be treated by a qualified environmental protection company.

The whole process is now fully operational.
