Mechanical pre-treatment with siClaro® fine screenwww.martin-membrane.comMechanical pre-treatment for MBR plants with siClaro® fine screensField of use • Mechanical pre-treatment in distributed water treat-ment plants • Fine screening through openings with a diameter of less than 3 mm makes it ideally suited for membrane aera-tion systems • Maximum flow rate of 7 l/s Advantages• Simple and low-cost compact design• High hydraulic throughput with even the smallest open-ing diameters since the screen‘s entire circumferential surface area is effective • Combines the functions of screening wastewater, sepa-rating grit and washing out organic matter all in one device • Upgradeable with a discharge screw including dewater-ing and hygienic packaging Objective Hairs, fibrous materials, etc. can form unwanted agglom-erations and clog the membrane bioreactor and therefore have to be separated from the raw wastewater to ensure the membrane aeration plant‘s safe and low-maintenance op-eration. But the organic contents of the screenings should be returned to the biological treatment stage as a carbon source. Distributed membrane wastewater treatment plants need a simple and low-cost mechanical pre-treatment to separate screenings and sand. The siClaro® fine screen combines a vertical fine screen with screenings washer and a circular grit chamber and thus sat-isfies these requirements. The separated solid matter can be discharged via a dewa-tering screw press but the collected screenings and sand can also be sucked off directly from the tank with a suction vehicle.www.martin-membrane.comFunction The wastewater enters the screen unit tangentially and is forced into a cyclic flow (teacup effect) whereby the re-sulting vertical force moves the sand grains to the hopper throat. Light suspended and solid matter rise in the centre of the circular grit chamber and are retained by the cylindrical screen element. Several spirally arranged brushes clean the screen cylinder. The solid matter is transported to the raw water tank op-posite to the inflow. The raw wastewater washes organics out of the rising solid matter during its multiple circulationsOur patented screen system has proven successful for the separation of solid matter in marine applications and up-stream of membrane aeration plants for many years.
