Rectangular Aquaculture Equipment Ras Biological Filter Bio Filter for Aquaculture

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Biological Filtration: Designed to efficiently process water in aquaculture systems through multi-stage biological filtration, supporting healthy aquatic ecosystems.
  • Waste Management: Features a sloped bottom for optimal drainage and minimal residue buildup, ensuring clean and hygienic water circulation.

Key features

  • 1. Corrosion-Resistant PP Material

    • With a durable polypropylene (PP) construction, you can ensure long-lasting performance in aquatic environments prone to chemical exposure or saltwater corrosion. This material outperforms traditional plastic filters in resisting degradation over time.*

  • 2. Sloped Bottom Drainage Design

    • With the sloped bottom and strategically placed ports, you can achieve efficient waste removal and minimize residue buildup, simplifying maintenance compared to flat-bottomed filters.

  • 3. Space-Efficient Rectangular Shape

    • With a rectangular design optimized for aquaculture tanks, you can maximize space utilization in confined or commercial setups, unlike round filters that occupy more floor area.

  • 4. Commercial-Grade Continuous Operation

    • Designed for fish farms and industrial aquaculture, this filter supports uninterrupted operation to maintain stable water quality, ideal for large-scale systems requiring 24/7 performance.

  • 5. Food-Grade Material Compliance

    • With PP material certified for food safety, you can ensure compatibility with aquatic ecosystems without compromising water purity, meeting regulatory standards for aquaculture systems.

Product details

Rectangular Aquaculture Equipment Ras Biological Filter Bio Filter for Aquaculture

The BOWDIA Rectangular Aquaculture RAS Biological Filter is a durable, industrial-grade filtration system designed for efficient water management in aquaculture and fish farming. Constructed from PP (polypropylene) and plastic composites, it features a sloped bottom for seamless drainage and two reinforced ports for easy fluid intake/discharge. Its rectangular shape optimizes space in commercial setups, while the brand’s robust design ensures longevity in demanding environments.

Supplier's note

  1. Technical Breakthroughs:

    • Material Composition: PP/Plastic hybrid reduces weight by 20% compared to steel tanks, lowering installation costs.
    • Sloped Bottom Design: 5° angle ensures 100% drainage, eliminating stagnant water and reducing bacterial growth.
    • Port Reinforcement: Enhanced sealing technology cuts leakage risks by 40% versus industry benchmarks.

  2. Optimal Version Selection:

    • Base Model: Suitable for small-scale farms or low-flow systems needing cost-effective solutions.
    • Advanced Model: Ideal for medium-sized operations requiring acid/alkali resistance (e.g., shrimp farms using chemical treatments).
    • Pro Model: Best for large RAS systems handling corrosive chemicals (e.g., seawater desalination). With triple-industry-grade chemical resistance, it ensures safe operation in harsh environments. Pair its 2.5 L/s port capacity with high-volume filtration needs to maintain optimal water quality.

*Note: All performance metrics are relative to the Base Model’s specifications.
