Applications

The projects and studies carried out by ZEWATECH in different fields of application with extraordinary results for the reduction of waste that is difficult to treat with conventional technologies.

In recent years, thanks to collaboration with different technological centres, we have developed ZLD (Zero Liquid Discharge) systems which have enabled many industries to reduce their environmental impact to 100%.

Our flexibility and availability of pilot plants for testing any product and application make it easier for our customers to guarantee any project in advance.

These are the different fields of application of our technology, always with maximum performance and respect for the environment.
