The filter is modular and saves space: The system is based on a standard disc filter unit, which is designed in a modular manner, and users can choose according to their needs. It is flexible and variable, and has strong interchangeability. The system is compact and occupies a very small area. It can be flexibly installed in the corner space. For example, the equipment that handles about 300m3 / h occupies only about 6m2 (general water quality, filtration level 100μ).
