水产养殖中的活性炭

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)

解决方案概述

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.

主要优势

  • 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.
  • Larger Floc Formation: Promotes sludge aggregation, increasing particle size and improving solid-liquid separation.

2. Recirculating Aquaculture Systems (RAS) for Advanced Purification

解决方案概述

Biological Activated Carbon (BAC) filters are used in RAS for post-treatment after mechanical and biological filtration. Microorganisms colonize the carbon surface, enabling simultaneous adsorption and biodegradation of pollutants.

主要优势

  • Effective Nitrogen Compound Removal: Achieves high removal rates of ammonia and nitrite through microbial degradation, meeting stringent water reuse standards.
  • Water Reusability: Produces effluent suitable for recirculation, reducing freshwater dependency and minimizing environmental discharge.
  • Dual Adsorption-Biodegradation: Combines physical adsorption of organics/COD with biological degradation, enhancing overall treatment efficiency.
  • Adaptability to Low Loads: Efficiently treats trace pollutants even at low inlet concentrations, unlike conventional activated carbon.

3.Biofloc Technology (BFT) Carbon Source Supplementation

解决方案概述

Activated carbon serves as a carbon source in biofloc systems to adjust the carbon-to-nitrogen (C/N) ratio. This stimulates heterotrophic bacterial growth, converting toxic nitrogen compounds into microbial protein (bioflocs).

主要优势

  • Toxin Conversion: Accelerates transformation of ammonia and nitrite into non-toxic bioflocs, improving shrimp/fish survival rates.
  • Water Quality Stabilization: Reduces accumulation of harmful nitrogen compounds and maintains balanced microbial communities.
  • Nutritional Supplement: Bioflocs serve as supplemental feed, enhancing growth efficiency and reducing feed costs.
  • System Resilience: Mitigates water exchange requirements and supports disease resistance in intensive farming.

4. Dedicated Purification for Seafood Holding Tanks

解决方案概述

Granular activated carbon (GAC) is integrated into filtration units of seafood holding tanks (e.g., restaurants, supermarkets) to adsorb impurities and maintain water clarity during live seafood storage.

主要优势

  • Multi-Contaminant Removal: Efficiently adsorbs residual chlorine, heavy metals, odors, and organic matter, ensuring a clean habitat.
  • Extended Seafood Vitality: Preserves dissolved oxygen levels and reduces stress, prolonging seafood survival and freshness.
  • Algae and Odor Control: Inhibits algal blooms and eliminates (fishy odors), enhancing visual and olfactory water quality.
  • Ease of Deployment: Simple installation in filter bags/cartridges with minimal maintenance.

5. Emergency Water Quality Management

解决方案概述

Activated carbon is used as a short-term intervention to adsorb sudden surges of organic pollutants, medications (e.g., antibiotics), or toxins during water quality crises.

主要优势

  • Rapid Contaminant Adsorption: Quickly binds organic toxins, residual drugs, and hydrogen sulfide, preventing acute toxicity.
  • Water Clarity Restoration: Removes turbidity and discoloration caused by dissolved organics or algal byproducts.
  • Non-Disruptive Application: Compatible with existing systems without altering water chemistry parameters like pH.
  • Temporary Nitrification Support: Lowers carbon-to-nitrogen ratio to aid (nitrification) system recovery during imbalances.
