2H BIOdek®-IFAS SYSTEM AND COMPONENTS Solution to Upgrade and Extend Activated Sludge Plants 2H BIOdek® KVP 623 2H IFAS mit BIOdek® KVP 623 IFAS (Integrated Fixed Film Activated Sludge) combines the advantages of fixed film technology i. e. submerged fixed beds (SAF) and conventional activated sludge (CAS). By adding high surface media to an activated sludge basin additional biomass will grow on the media increasing the operative sludge age. Thus, IFAS offers a possible performance increase up to 40% without new aeration tanks. The 2H IFAS system can be supplied as plug and play modules including the high surface media, aerators or agitators and installation cage. The aerators are individually selected for carbon- and nitrogen removal requirements. In the case of denitrification, the systems includes an agitator to move water through the media. In our manufacturing process we use premium materials for high quality requirements. For more than 40 years we have been consistently developing and improving fills for trickling filters and contact aeration. This puts us today in the position of a leading supplier of biofilm technology. You may profit from our experience gained in equipping hundreds of biofilm plants. We will be glad to support you in the optimal design of our IFAS modules for your individual case. Advantages of our 2H IFAS System • Increase of sludge-age and active biomass without extra tanks • Fixed film is not affected by bulky or pinpoint sludge • Better sludge settling characteristics • Simple retrofitting under operation • Decades of experience with structured fills for wastewater treatment • Plug and play modular design for step by step upgrades • High surface area for biofilm growth • Environmental friendly, impact and ageing resistant PP • KVP/KVC media types can be installed with continuous vertical channels High performance results in high biomass growth! 2H BIOdek® with vertical channels reliably releases excess sludge into the water column with minimal clogging risk. The straight channels ideally support the water circulation which is induced through optimal aeration under t
