Shockproof Hydrophilic K3 Plastic HDPE Material MBBR Bio Media For Fish Farm
product introduction
MBBR filter media is a novel biologically active carrier, it adopts scientific formula, depending
on the nature of water, blending a variety of beneficial microorganisms grow quickly attached trace elements in polymer materials, through a special process modification, constructed, with more than large surface area, hydrophilic, high biological activity, biofilm fast, good effect, good impact resistance.
Main feature:
Special formula and production technology, accelerating biological film formation ;
Larger effective surface area, obtaining more microorganism;
By bio-film decomposing technology, saving sludge return process;
High-efficiency in denitrification and dephosphorization, improving the water quality;
Lower energy consumption, saving space and shorten technology process.
MBBR Technology and Biofilm Carries
MBBR technology is based on the biofilm principle with an active biofilm growing on small specially designed plastic carriers that are kept suspended in the reactor. The technology utilizes the advantages of both activated sludge and other biofilm systems (e.g. biofilters, biorotors etc.) without being restrained by their disadvantages.
The carriers are designed to provide a large protected surface area for the biofilm and optimal conditions for the bacteria culture when the carriers are suspended in water.
Solutions based on MBBR technology is mainly used in the following applications:
+ For new plants, especially those requiring a small footprint and easy operation, for BOD/COD and nitrogen removal
+ As a high loading system in front of existing biological treatment - roughing reactor
+ To increase the amount of nitrifying bacteria in existing activated sludge system using the carrier in a hybrid plant to meet ammonia limits
+ To implement post-treatment to existing plants for process improvements

MBBR Technology
Technical Details
The aerated MBBR uses, as the activated sludge process, the whole volume of an open tank. It is defined as a biofilm system, as the biomass is growing on carriers that move freely within the reactor volume and are kept within the reactors by a sieve at the reactor outlet. The system can be used either for aerobic or anoxic processes. In aerobic processes the biofilm carriers are kept in suspension by the agitation created by air from aeration diffusers, while in anoxic processes a mixer keep the carriers in movement.
