ZDDQ solutions for efficient and safe processes in the water-management industry.

The provision of an environmentally friendly water supply is one of the greatest challenges of the 21st century. In order to achieve the greatest degree of energy efficiency possible, power generation plants (e.g. solar power plants) are increasingly being integrated into modern treatment facilities, including frequency converters, in order to operate the electrical pumps with the power generated. However, these pumps can cause disruptive electric harmonics that make the use of active filters a necessity. Furthermore, many countries have complex regulations in place to ensure that power generation plants are properly connected to the power grid, and these regulations pose additional challenges.
With innovative products, ZDDQ offers its customers a wide range of possible solutions to address the challenges described above.
