Aquaponics Lightweight Expanded Clay Pebble As Bio Filter Media for Waste Water Treatment

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Bio-Filtration Media: Designed as a lightweight expanded clay aggregate (LECA) for efficient wastewater treatment in aquaponics systems. The porous, circular pellets provide a large surface area for bacterial colonization, breaking down ammonia and nitrites.
  • Plant Support & Aeration: Acts as a growth medium in hydroponic/aquaponic setups, ensuring root stability while promoting oxygen exchange due to its airy structure.

Key features

  • 1. Material Technology

    • With 100% natural expanded clay, ensure durable and eco-friendly filtration in harsh environments like wastewater treatment. The porous structure promotes efficient contaminant absorption while resisting chemical degradation.

  • 2. Performance Parameters

    • With a lightweight design, reduce handling effort by up to 30% compared to traditional gravel aggregates* [*Disclaimer: Based on internal testing; actual results may vary]. Ideal for easy installation in aquaponics systems and hydroponic setups.

  • 3. Performance Parameters

    • With a porous surface, enhance water absorption by 40% for optimal root aeration and moisture retention in horticultural applications* [*Disclaimer: Based on internal testing; actual results may vary].

  • 4. Scenario Solutions

    • Designed for aquaponics systems, provide a reusable biofilter media that supports sustainable waste treatment and plant growth in closed-loop environments.

  • 5. Certification Standards

    • Eco-friendly certification ensures safe use in organic gardening and food-safe wastewater systems* [*Disclaimer: Certification details subject to manufacturer’s confirmation].

Product details

Aquaponics Lightweight Expanded Clay Pebble As Bio Filter Media for Waste Water Treatment

Aquaponics Lightweight Expanded Clay Pebble is a 100% natural, lightweight bio-filter media designed for efficient wastewater treatment and horticultural applications. Crafted from expanded clay, it combines insulating properties, high porosity, and customizable particle sizes to meet diverse environmental and structural needs.

Supplier's note

  1. Technical Breakthroughs:

    • High Porosity (50% in Pro Model): Triple the surface area for microbial colonization compared to gravel, boosting biofiltration efficiency.
    • Ultra-Low Density (0.3 g/cm³): 40% lighter than traditional aggregates, reducing material costs in large-scale projects.
    • Customizable Particles: Variable sizes allow precise engineering for hydroponic beds or industrial drainage systems.

  2. Optimal Version Selection:

    • Base Model: Ideal for home aquaponics or small-scale landscaping where standard filtration suffices.
    • Advanced Model: Preferred by commercial growers needing adjustable particle sizes for layered hydroponic systems.
    • Pro Model: Engineers and industrial wastewater managers choose this for its NSF/ANSI certification and extreme porosity, ensuring compliance with strict environmental regulations.

With the Pro Model’s 50% porosity, you can achieve 20% faster nutrient cycling in aquaponics than traditional media. Pair its low density with high water absorption to create lightweight, self-draining green roofs that retain moisture year-round.
