The Aquasust Super MBBR Media Is An Attached-Growth Biological Treatment Process That Uses Special Carriers To Create A Large Surface Area For Biofilm Growth
The Aquasust MBBR plant can be designed as a stand-alone treatment process or to provide pre-treatment, effluent polishing, nitrification, or nutrient reduction. The MBBR treatment process is typically used for smaller (< 10,000 gpd) flows, ammonia polishing, and high-strength wastewater pre-treatment.
The Aquasust MBBR reactor consists of a tank filled with plastic media having specific gravity slightly less than 1.0. The large surface area of the media provides the abundant contact area for bacterial attachment. Biomass grows on the surfaces of the media as a thin film. Medium or coarse bubble diffusers placed at the bottom of the reactor maintain a dissolved oxygen (DO) concentration of about 4 – 5 mg/L for BOD removal and nitrification. To keep the media from flowing out of the tank, screens are placed on the discharge outlet piping. A clarifier may be placed downstream of the MBBR to separate sloughed solids from the treated effluent. The settled solids are wasted from the system and no sludge recycle is required for this process.
MBBR technology employs thousands of polyethylene biofilm carriers operating in mixed motion within an aerated wastewater treatment basin. Each individual biocarrier increases treatment capacity by providing protected surface area to support the growth of heterotrophic and autotrophic bacteria within its walls. It is this high-density population of bacteria that achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation.
This technology provides cost-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive biofilm. Additionally, the biofilm attached to the mobile biocarriers within the system automatically respond to load fluctuations.
