Biofloc Reactor

Development of biofloc system It may take a few weeks depends on the biomass. The temperature was stable at 26 1 C in the climate incubator which was thought to be favorable for the growth of bioflocs.

Biofloc reactor. Biofloc or Raceway system maintains a sufficient amount of carbohydratesCarbon present in these carbohydrates promotes heterotrophic bacteria to multiply and synthesize ammonia so maintain the water quality parametersAmmonia produced from the nitrogenous feed as a metabolic product pollutes the water quality. Improvising bio-strata wheels as fluidized bed produces an efficient accumulation of Amphora biomass. There are strong economic.

Serves as seeding for biofloc formation. Approximately 150 ml sludge was added to every reactor every. Biofloc culture is Eco-friendly in nature cost-efficient in case of feeding management.

1 The reactor must be tightly sealed. In places where water is scarce or land is expensive more intensive forms of aquaculture must be practiced for cost-effective production. Denitrification and Dissimilatory Nitrate Reduction to Ammonium DNRA Activities in Freshwater Sludge and Biofloc from Nile Tilapia Aquaculture Systems.

A biofloc reactor was designed and fabricated and the process optimization of important parameters for floc development was carried out. The water of the biofloc reactor can be recirculated into the culture tank andor bioflocs can be harvested and used as a supplementary feed. This system requires less land area water supply.

Advantages of the Biofloc culture system.

The flow into the reactor must be very very slow. The 20-L reactor has the capability to hold a stock of more than 150 billion cells. The reactor designs on the web all have flow.

It gradually reduces the environmental impact mitigation by controlling water quality parameters. The crude protein content of biofloc in the IA reactors and CA reactors were 3447 and 3078 respectively. Transition is fast with tilapia longer with shrimp Add carbon if TAN is above 2 mgl Adding clay wheat bran etc.

Also use a limited or zero water exchange system. Transition foam formation then it get brown. Download Full PDF Package.

Each reactor contained 20 liters working volume and was continuously mixed using a magnetic stirrer during 22 days until floc harvesting. In the reactor the micro-roughness and micro-architectural miniature laminar sub-layers of the bio-strata wheel serve as bio-adhesion capacitors. Each reactor had a diameter of 20 cm and a liquid filled height of 20 cm 6 L working volume.

Most web designs meet this criterion. The waste water from the culture tank is brought into the biofloc reactor where a carbon source is added in order to stimulate biofloc growth. No significant differences were observed between the two reactors.

These reactors have established that denitrifying reactors have several absolute requirements. The waste water from the culture tank is brought into the biofloc reactor where a carbon source is added in order to stimulate biofloc growth. In addition each reactor was supplied with air by means of a porous diffuser at the bottom of the reactor.

The contents of crude protein and polysaccharides in the biofloc in the IA reactors were greater than those of the CA reactors though no significant difference was observed. The water of the biofloc reactor can be recirculated into the culture tank andor bioflocs can be harvested and used as a supplementary feed. Journal of Water and Environment Technology 2014.

Biofloc systems were developed to improve environmental control over production.
