Performance of Small Boss Biomedia in Recirculating Aquaculture System
One of the principles of operation of the RAS is to treat the wastewater produced by the aquarium for reuse in the system. In RAS, water quality management is an important aspect of fish production.
RAS wastewater contains nitrogenous waste, suspended inorganic particles, and many bacterial flocs derived from leftover feed, fish feces, dead fish, and bacteria that degrade water quality and can be toxic to aquatic organisms. In this regard, in order to prevent and provide a suitable and sustainable living environment for marine organisms, effective water treatment technologies are required to remove the above substances.
The RAS wastewater treatment process is done in different stages. First, suspended and dissolved organic solids are removed using settling, settling chamber, screen filter, or foam fractionator equipment. Second, nitrogen-containing compounds are removed by microbial treatment through the nitrification process. Afterwards, water conditioning, such as disinfection and oxygenation, and a carbon dioxide (CO2) stripping process take place. Finally, the treated water is returned to the fish tank for reuse.
The increasing number of aquaculture facilities based on RAS or recirculating aquaculture system technology proves the high advantages of this technology.
Small Boss, a leader in MBBR Media manufacturer since 2002, research more than 15 types bio media which is widely used in recirculating aquaculture systems. It's made of 100% virgin HDPE, Non-toxic environmental protection, high impact strength, suitable density(0.92 to 0.98g/cm3). Our bio media will float into the water firstly. It will be suspended state after the bacteria grow in mbbr carrier. The bacteria can decompose the organic matter, dislodge the total nitrogen, COD, BOD.
What makes our MBBR biomedias different? Let's dive into the advantages of our products that appeal to our customers:
Before use: The color is nature white
1. Unparalleled biomedia adhesion: Our mbbr biomedia has a special surface treatment, which makes it have an extraordinary ability to adsorb and retain biomedia. This property increases the efficiency and effectiveness of the filtration process, ensuring cleaner, healthier water.
2. Maximize biological growth: Our biomedia are engineered with high surface area and high porosity to allow beneficial microbes to proliferate. This results in higher biomass, which improves water treatment performance and quality.
3.Hydraulic efficiency: The geometric configuration of our mbbr biomedia is carefully designed using the principles of hydrodynamics. This design creates a strong three-dimensional flow in the water, optimizing the removal of impurities and ensuring the best water treatment results.
4.Rapid biofilm formation: We add trace elements such as pure water free radicals to our MBBR biomedia. This innovative additive accelerates biofilm formation, reducing start-up time to 3-15 days. Our customers can experience the advantages of our biomedias in a very short period of time.
Use for 7 days: The bio media changes color
Use for 15 days: The membrane is relatively mature
Use for 30 days: The membrane becomes thicker
5. Excellent durability and performance: Our mbbr biofiller has excellent impact resistance, strong air shear ability and high dissolution rate. These properties not only ensure longevity, but also maintain high filtration efficiency for cleaner water for longer.
6. Simplified implementation and cost-effectiveness: The self-supporting nature of our mbbr biomedia eliminates the need for additional supports or structures, promotes easy fluidization and minimizes energy consumption. Additionally, the compact design saves valuable space and allows for more efficient use of resources.
