By the vast fish ponds, where ripples shimmer and fish glide, lies a thriving ecosystem. As the world’s largest aquatic producer, China’s 2024 output reached 73.66 million metric tons. Yet, high-density aquaculture faces severe water quality challenges—eutrophication, excessive ammonia levels, and algal blooms—silently eroding productivity.

How to keep every drop of water crystal clear? How to ensure healthy growth for fish and shrimp? Aoqun’s bio-friendly hydrophilic filter brush acts as a precision “aquatic purifier,” delivering efficient, stable, and sustainable water management for modern fisheries.

Aoqun Filter Brushes: The "Ideal Home" for Beneficial Microbes

Water purification hinges on cultivating beneficial microbes, which require a stable, high-surface-area habitat. Aoqun’s bio-friendly hydrophilic filter brush (Patent: ZL 201710365869.X) features a cross-diamond structure, increasing adsorption area by 10x compared to conventional brushes. This enables rapid colonization of nitrifying and denitrifying bacteria, forming a robust biofilm system.

✅ 70% Faster Biofilm Formation: Establishes a stable purification system within 3 days.
✅ 90% Ammonia Removal: Far exceeds traditional brushes (40–50%).
✅ 50% Longer Lifespan: Durable stainless steel frame reduces long-term costs.
✅ Reduced Water Replacement: Frequency drops from weekly to monthly, saving 30% in water/electricity costs.
✅ Lower Chemical Use: Antibiotic usage decreases by 50% post-stabilization, aligning with green farming standards.

Beyond Fisheries: A Multi-Scenario Eco-Tool

Aoqun’s filter brushes excel not only in aquaculture but also in broader water and industrial purification:

1. Fisheries & Spawning

Serve as shelter brushes for crabs and shrimp, boosting survival rates in projects like Hainan and Hubei aquaculture bases and the Huanghai Fisheries Research Institute’s Wanning Base.

2. Urban Water Remediation

Played key roles in major projects: Guangzhou Asian Games City water treatment, Pearl River banks, and Hangzhou West Lake restoration.

3. Filtration Systems

Rooftop Filtration: Blocks debris, prevents pipe clogs, and resists UV degradation.

Wind Turbine Systems: Corrosion-resistant brushes endure harsh environments, extending equipment lifespan.

Future Vision

“Quality brushes create quality water; quality water nurtures quality fish.” From a single brush to a pond of crystalline waves, Aoqun will continue advancing “high-precision, cutting-edge” technology to redefine productivity, enhance water purity, and ensure sustainable fisheries. Together, let’s write a new chapter in green aquaculture!
