The SPIRAL SCREEN is useful to pre-treat any kind of sewage water be it municipal or industrial. Following the application, there are two different versions: a screw screen directly installed in the channel or a screw screen supplied complete with a tank, with liquid inlet and outlet flanges, and, at request, with the lateral by-pass screen. For both models, you can choose the version with or without a compacting zone. The main advantages of these models of machines are mainly the low cost of initial investment and the subsequent little maintenance required.
