210 m³ Amiscreen storage sewer in Zwickau
An impressive Amiblu storage sewer with integrated Amiscreen system was successfully installed in the German city of Zwickau. Waterworks Zwickau opted for Flowtite GRP pipes by Amiblu to realize the sewer; concrete pipes were no option due to their bigger wall thickness and respectively smaller capacity at same diameter. Further decisive factors were the GRP pipes’ smooth inner surface and long, low-maintenance lifetime. The 30 m long Flowtite storage sewer has a diameter of 3000 mm and a retention capacity of 210 m³. It features two inspection chambers DN 1000 and a rainwater overflow shaft DN 3200. Two 28 m long Amiscreen elements DN 800 with a screening surface of 141 m² ensure that all suspended solids are reliably filtered from the wastewater. Amiblu sales manager Uwe Napierski explains the system’s benefits: „Amiscreen consists of perforated circular elements that are mounted to the sewer channel walls. Conventional rakes only manage to filter about 70% of suspended solids, Amiscreen retains 100 % of all solids larger than 8 mm inside of the sewer. Also, the screening surface is 15 to 25 times bigger than comparable filter surfaces.” The system operates without any mechanical cleaning elements or other moving parts and does not require an external power supply. Zwickau’s new Amiblu sewer solution with Amiscreen features a cleaning capacity of up to 3161 l/sec.
