DC HDPE 05 RAS un rūpniecisko notekūdeņu attīrīšanai
This high-efficiency MBBR (Moving Bed Biofilm Reactor) media is specifically engineered for robust biofilm cultivation in demanding aquaculture and wastewater treatment applications. Its unique design features five large, strategically placed through-holes and prominent vertical stripe protrusions across the entire outer surface. This configuration delivers superior performance by maximizing protected surface area for microbial attachment, enhancing nutrient diffusion through turbulent flow promotion, and facilitating optimal biofilm thickness control via self-cleaning mechanisms. The robust High-Density Polyethylene construction ensures excellent durability, chemical resistance, and long operational life within bioreactors.
Apraksts
How can the issues of MBBR media wear and replacement costs be addressed?
The media is subject to constant wear and tear during continuous operation. For example, PP biofilm chips may need to be replaced in less than three years. In contrast, HDPE MBBR media manufactured by Decycle has a normal service life of over 15 years.
DC HDPE 05 RAS un rūpniecisko notekūdeņu attīrīšanai
Šis augstas efektivitātes MBBR (kustīgā slāņa bioplēves reaktora) biomateriāls ir īpaši izstrādāts spēcīgai bioplēves kultivēšanai prasīgās akvakultūras un notekūdeņu attīrīšanas sistēmās. Tā unikālajā konstrukcijā ir pieci lieli, stratēģiski izvietoti caurumi un izteikti vertikāli svītru izvirzījumi visā ārējā virsmā. Šī konfigurācija nodrošina izcilu veiktspēju, maksimāli palielinot aizsargāto virsmas laukumu mikrobu piestiprināšanai, uzlabojot barības vielu difūziju, izmantojot turbulentu plūsmu, un atvieglojot optimālu bioplēves biezuma kontroli, izmantojot pašattīrīšanās mehānismus. Izturīgā augsta blīvuma polietilēna konstrukcija nodrošina izcilu izturību, ķīmisko izturību un ilgu ekspluatācijas laiku bioreaktoros.
How can difficulties with biofilm formation during the start-up of MBBR MEDIA be resolved?
During start-up, maintain the water temperature at 20–30 °C and keep the pH stable at 7–8. After adding the media, shut off the inlet and outlet water and carry out continuous aeration for 5–8 days. During this period, a small amount of powdered feed (5–10 grams per cubic metre) and aerobic denitrifying bacteria (5 grams per cubic metre) may be added to accelerate start-up. Introduce the media in 2–3 batches to avoid accumulation caused by adding too much at once. Biofilm formation typically takes more than 30 days to become visible to the naked eye. To determine whether start-up has been successful, monitor changes in ammonia-nitrogen and nitrite concentrations at the inlet and outlet, rather than relying on visual inspection.

1. Augsts īpatnējais virsmas laukums
DC 05 has a specific surface area of >1000 m²/m³, providing ample attachment space for nitrifying bacteria and helping to improve biological filtration efficiency and ammonia-nitrogen removal capacity in recirculating aquaculture systems.
2. Compact 5-Hole Structure
The DC 05 features a compact, 5-hole cylindrical structure that provides both internal and external attachment surfaces for microorganisms. The internal channels effectively protect the biofilm, reduce microbial loss caused by water flow, and promote stable biofilm formation.
3. High Carrier Quantity
DC 05 contains more than 990,000 particles per cubic meter. The media is evenly distributed throughout the biofilter, improving contact efficiency between the aquaculture water, dissolved oxygen, and microorganisms, thereby enhancing overall filtration performance.
4. Efficient Nitrification Performance
DC 05 provides an ideal growth environment for nitrifying bacteria, promoting the conversion of toxic ammonia nitrogen into less toxic nitrogen-containing compounds, thereby helping to maintain stable and safe water quality in recirculating aquaculture systems.
5. Excellent Fluidization Performance
DC 05 has a density of 0.94–0.97 g/cm³, which is close to that of water. Under aeration or circulating water flow, the media maintains a good state of suspension and fluidization, ensuring that the biofilm remains in constant and thorough contact with the aquaculture water.
6. Made from 100% White Virgin HDPE
DC 05 is made from 100% virgin white HDPE and offers excellent chemical stability, corrosion resistance, and weather resistance, making it suitable for long-term, continuous operation in recirculating aquaculture systems.
7. Ilgs kalpošanas laiks
DC 05 has a service life of over 15 years, which reduces the frequency of media replacement and lowers the long-term operating costs of recirculating aquaculture systems.
8. Flexible Filling Ratio
The recommended fill rate for DC 05 is 15%–70%. It can be flexibly configured based on stocking density, feed intake, and biological filter design to meet the needs of recirculating aquaculture systems of various scales.
9. Suitable for High-Density Aquaculture
DC 05 combines a high specific surface area with a compact structure, making it particularly suitable for high-density recirculating aquaculture systems, where it provides stable and efficient biological filtration for high-density aquaculture.
