DC HDPE 05 Pentru RAS și tratarea apelor uzate industriale
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.
Descriere
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 Pentru RAS și tratarea apelor uzate industriale
Acest mediu MBBR (Moving Bed Biofilm Reactor - reactor cu biofilm cu pat mobil) de înaltă eficiență este special conceput pentru cultivarea robustă a biofilmului în aplicații solicitante de acvacultură și tratare a apelor uzate. Designul său unic prezintă cinci orificii mari, plasate strategic, și proeminențe verticale proeminente în dungi pe întreaga suprafață exterioară. Această configurație oferă performanțe superioare prin maximizarea suprafeței protejate pentru atașarea microbiană, îmbunătățirea difuziei nutrienților prin promovarea fluxului turbulent și facilitarea controlului optim al grosimii biofilmului prin mecanisme de autocurățare. Construcția robustă din polietilenă de înaltă densitate asigură o durabilitate excelentă, rezistență chimică și o durată lungă de viață în cadrul bioreactoarelor.
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.
Cere un citatWhy do fish farmers specialising in high-value species such as salmon, as well as designers of recirculating aquaculture systems, prefer to use the DC 05?
1. Suprafață specifică ridicată
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. Performanță excelentă de fluidizare
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. Fabricat din 100% HDPE alb virgin
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. Durată lungă de viață
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. Raport de umplere flexibil
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.
