The compact desanding plant is particularly suited for use in mechanical tunnel boring. The plant is installed in a standard high cube container frame (20 ft.), which enables easy and fast mounting on any standard container using container connectors. The basic plant can be expanded with a desilter attachment to optimize the separation of solids from 60 µm to 20 µm. In addition, an upstream GS 425-V with variable sieve incline can be used to ensure optimal separation in difficult soil conditions.
