YUTANK biological filter barrel removes ammonia, nitrite, nitrate, CO₂ and organics by beneficial bacteria. Made of food-grade PP, compact 3–4 stage filtration, plug-and-play, no civil work needed for aquaculture RAS.
In recirculating aquaculture systems (RAS), biological filtration is critical to stabilize water quality and protect fish and shrimp health. Toxic substances such as ammonia nitrogen, nitrite, nitrate, carbon dioxide, and organic matter accumulate rapidly and threaten survival.
The biological filter barrel provides a stable habitat for beneficial nitrifying bacteria to decompose and convert harmful pollutants. As a key purification unit, it works with drum filters, protein skimmers, and UV sterilizers to achieve a closed‑loop, eco‑friendly aquaculture system.
A biological filter barrel is a specialized device for cultivating beneficial bacteria. It uses microbial metabolism to remove dissolved and semi‑dissolved organic pollutants, converting toxic nitrogen compounds and gases into harmless substances like H₂O, N₂, and CO₂.
With no civil construction required, it can be installed and operated immediately. Made of high‑quality food‑grade PP material, it ensures non‑toxic, safe, and stable operation for long‑term use.
Effectively removes NO₂, NO₃, NH₄⁺, CO₂, and organic matter. Beneficial bacteria convert toxins into harmless H₂O, N₂, and CO₂, greatly improving water stability.
Made of high‑quality food‑grade polypropylene (PP): non‑toxic, odorless, lightweight, sturdy, corrosion‑resistant, aging‑resistant, and long service life.
Ready for use upon installation; no concrete or construction work needed, saving time and cost for rapid deployment.
Large filtration area, compact size, and high treatment efficiency. Filtration, biodegradation, and waste discharge run simultaneously without interrupting system operation.
Strong performance in removing water‑soluble and semi‑soluble organic compounds, reducing biofilter load and improving overall RAS efficiency.
Creates an optimal living environment for beneficial bacteria, ensuring stable and continuous purification effect.
