Advanced/Commercial Treatment Systems

  Moving bed biological reactor

PuraMax from Anua can be designed and installed for pretreatment from a variety of commercial waste stream sources. It is a moving bed biological reactor (MBBR) and is suitable for high-strength waste pretreatment. Following a primary tank, biological treatment is achieved through an attached growth process. Recycled plastic biocarriers, suspended in the 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 by gravity to a clarifier for solids separation. It is compatible with most off-the-shelf tanks, and is suitable for high-strength applications such as food service businesses. It operates effectively under shock loading, underloading and intermittent flow. 336/547-9338; www.anua-us.com.

  High-strength sewage treatment plant

MyFAST Wastewater Treatment Systems from Bio-Microbics are designed for a flow range of 10,000 to more than 160,000 gpd, making them ideal for use in new construction, renovations and repairs for nitrogen-sensitive areas. The systems combine a submerged fixed film process with a passive recycle process. They maintain microbial growth during low, average and peak usage, increase sludge settleabilty and eliminate sludge bulking. Multiple biological, biochemical, chemical and physical processes occur simultaneously within the system to consistently reduce nitrogen levels, including nitrates and all other nitrogen species, at high percentage rates. The treatment quality can allow for reductions in distance to groundwater and field size requirements. 800/753-3278; www.biomicrobics.com.
