ATUs - Moving bed biological reactor

The PuraMax MBBR from Anua achieves biological treatment through an attached growth process. Recycled plastic biocarriers suspended in the Infiltrator IM Series tank provide a large surface area for bacteria to attach and grow. An aeration grid supplies oxygen to the biofilm, along with the mixing energy required to keep the biocarriers suspended throughout the tank. Biosolids are naturally sloughed off the biocarriers, which along with the treated effluent flow to a clarifier for solids separation. It operates effectively under shock loading, underloading and intermittent flow. 336/547-9338; www.anua-us.com.
