... The situation For the new type of membrane bioreactors that have recently been put on the market the efficiency of conventional screens with typical bar spacings and perforations of 3-10 mm is no longer sufficient. Improved performance is required to ensure reliable and lowmaintenance operation of these plants. Since especially fibrous material and hairs are a hindrance as they produce undesired tressings, fine apertures are applied to remove such material, preferably square mesh. As river and sea outfalls frequently have only a mechanical screening stage, it is important to reduce the...

WASTE WATER Solutions Flow diagram of the ROTAMAT® Membrane Screen RoMem ... The applications The ROTAMAT® Membrane Screen is used for screening of municipal and industrial wastewater. The screen can be installed either directly in the channel or in a separate tank. Separation of hairs and fibres prior to membrane bioreactors The selection of the mesh size depends on the applied membrane system. Membrane modules are divided into hollow fibre and plate modules. Separation of fibrous material is particularly important prior to hollow fibre membrane plants as fibres may lead to tressing or...
