Buy Aquaculture Activated Carbon
Activated carbon is vital in aquaculture water treatment systems and is primarily used in filtration components, including various fluidized bed filters, canister filters, and dedicated contact chambers. Activated carbon has a highly porous structure that primarily works by adsorption to remove a wide spectrum of dissolved organic pollutants, tannins (the agent for yellow discolouration), unpleasant odours, and residual medications (such as antibiotics or dyes) from the water column. The purification of the water column is important to maintain optimum water quality, clarity, and a healthful environment for optimal production of fish and shellfish. Activated carbon mainly aids in, decreasing stress, limiting the potential for toxin build up, and improving the general hygienic state of the water, thereby improving the welfare of the aquatic organism. Activated carbon is particularly useful in recirculating aquaculture systems (RAS), where water reuse is intense, and in cases of needing to remove a medication, and to treating the water from organic-stained water. All spent activated carbon must be replaced regularly because, as tetrads of specific adsorption sites become full, the effectiveness of the activated carbon decreases.

Common Solutions and Applications of Activated Carbon in Aquaculture
1. Wastewater Treatment in Membrane Bioreactors (MBR-PAC Systems)
Visão geral da solução
Powdered Activated Carbon (PAC) use integrated with submerged Membrane Bioreactors (MBR) to treat salted aquaculture wastewater. The addition of PAC increases the removal of pollutants and reduces membrane fouling from salinity variability and organic loads.
Principais vantagens
- Improved Pollutant Removal: Significantly boosts COD, ammonia nitrogen (NH₄⁺-N), and nitrite nitrogen (NO₂⁻-N) removal efficiency compared to standalone MBR systems.
- Enhanced Membrane Performance: Reduces fouling by adsorbing soluble microbial products (SMP) and extracellular polymeric substances (EPS), extending membrane lifespan and maintaining stable flux.
- Salinity Resilience: Maintains treatment stability during salinity shocks by adsorbing dissolved organics and reducing protein content in sludge flocs.
