Description
DC 04-2 K1 MBBR Carrier for RAS
Decycle’s HDPE K1 MBBR media are the core microbial carriers used in Moving Bed Biofilm Reactor (MBBR) recirculating aquaculture systems. Manufactured from 100% virgin high-density polyethylene (HDPE), our K1 media are specifically designed for a wide range of biological filters and aquaculture systems, serving aquaculture farms, aquarium enthusiasts and water treatment contractors.
DC 04-2 K1 MBBR Media for Recirculating Aquaculture Systems
Ce média MBBR (réacteur à biofilm à lit mobile) en polyéthylène haute densité (PEHD) présente une conception cylindrique à 4 trous avec des stries verticales en surface. Conçu pour optimiser la fixation du biofilm et la diffusion des nutriments dans les systèmes aquacoles à recirculation, ces stries verticales augmentent considérablement la surface utile, améliorent le mélange hydrodynamique et réduisent la consommation d'énergie. Sa structure robuste assure une durabilité à long terme en mouvement continu, favorisant ainsi l'élimination efficace de l'ammoniac et des nitrites, essentielle à la pisciculture à haute densité.
How do you calculate how many cubic metres of K1 MBBR MEDIA your recirculating aquaculture system requires?
Simply provide your stocking density, the volume of the aquaculture water, the feeding rate, the daily feed intake and the protein content of the feed, and our engineers will be able to calculate this accurately for you.
Demander un devisWhy is the K1 MBBR MEIDA the ideal media for recirculating aquaculture systems?
1. Surface spécifique élevée
DC 04-2 (K1) has a specific surface area of >900 m²/m³, providing ample attachment space for nitrifying bacteria and helping to improve ammonia-nitrogen removal efficiency in recirculating aquaculture systems.
2. Suitable for Nitrifying Bacteria Growth
The DC 04-2 (K1)’s 4-hole cylindrical structure provides both internal and external attachment surfaces for nitrifying bacteria, enabling more stable biofilm growth. Nitrifying bacteria gradually convert harmful ammonia nitrogen in aquaculture water, helping to maintain a suitable growth environment for fish and shrimp.
3. Stable Biofilm Formation
In RAS systems, stable biofilm is essential for continuous ammonia removal. DC 04-2 (K1) provides protected surfaces for microorganisms, reducing the risk of biomass loss caused by water flow or aeration.
4. Excellent Fluidization Performance
With a density of 0.94–0.97 g/cm³, DC 04-2 (K1) is close to the density of water. Under aeration or water circulation, the media can remain suspended and fluidized in the biofilter, allowing full contact with aquaculture water and dissolved oxygen.
5. Compact Size and High Carrier Quantity
DC 04-2 (K1) is small in size, measuring Φ11×7 mm, with a density exceeding 930,000 pcs/m³. Its high density and uniform distribution help improve the contact efficiency between the media and the aquaculture water in biofilters, making it suitable for small- to medium-sized and high-density recirculating aquaculture systems.
6. Fabriqué à partir de PEHD vierge 100 % blanc
DC 04-2 (K1) is made from 100% virgin white HDPE material. It has stable chemical properties and is resistant to corrosion and aging, making it suitable for long-term use in recirculating aquaculture systems and biological filters at fish farms.
7. Longue durée de vie
With a service life of more than 15 years, DC 04-2 (K1) helps reduce media replacement frequency and long-term operating costs in aquaculture projects.
8. Taux de remplissage flexible
The filling ratio of DC 04-2 (K1) ranges from 15% to 68%, which can be adjusted according to fish species, stocking density, feeding amount, ammonia load and biofilter design.
9. Helps Maintain Stable Water Quality
In RAS, fish waste and feed residues continuously produce ammonia nitrogen. DC 04-2 (K1) supports the growth of nitrifying bacteria, helping reduce ammonia accumulation and maintain stable water quality for fish and shrimp growth.
