The centrepiece of the PASSAVANT MicroScreen MTSM is a rotating drum consisting of mesh baskets that are mounted together. The mesh baskets are covered with polyester screening mesh. It can be installed in a concrete chamber or in a steel or plastic casing.
Function
The raw water flows through the drum screen cage from the inside outwards and the debris sticks to the inside of the screen. The screen design causes the incoming raw water to dam up on the inside of the drum. If a defined differential head is exceeded between the incoming raw water and the outgoing clean water, the drum begins to rotate.
