RAS生物過濾池 – 穩定的生物過濾解決方案 | YUTANK

特徵

• 多區域內部設計
  分段式腔室可劃分專門的曝氣、沉降和生物膜生長區域。即使在進料負荷變化的情況下，這種結構也能穩定氨到亞硝酸鹽的轉化率。

• 有排水口的斜底
  每個水箱均配備精密角度底座和中央集水槽出口。這支援日常污泥沖洗—這是大多數國際 RAS 運作中的標準程序。

• 相容於 MBBR 和靜態介質
  從浮動式K1到結構化固定床，我們的槽體結構支援多種介質類型，並具有均勻的流動動力學。我們將相應地校準噴嘴佈置和流量。

• 重型材料選項
  根據農場水體化學特性，提供耐化學腐蝕的PP或海洋級HDPE材質。壁厚、加強筋和抗紫外線塗層均可客製化。

• 輕鬆改造現有系統
  進出水管配件可與傳統儲罐搭配。尤其適合全球客戶從混凝土或玻璃纖維儲罐升級。

• 服務艙口和媒體存取端口
  超大頂部端口可快速檢查培養基並清潔生物膜。可選配網籃，方便在收穫或清洗儲存槽時安全排出培養基。

• 穩定的生物群落錨定
  內部流動擋板可最大限度地減少死角，同時最大限度地保留氧氣——這是長期維持高密度生物群落的關鍵。

Packaging
Each biological filtration tank is individually wrapped using stretch film and reinforced corner guards. For international shipments, units are placed in fumigated wooden crates or heavy-duty pallet bases to prevent deformation or puncture during transit. All inlets/outlets are sealed with flange covers or PE bags to protect against dust and moisture.

Loading & Container Use
Tanks are nested where size permits, and vertical stacking is used for small-to-medium models to optimize cubic efficiency. A 20GP can typically load 10–15 units (1.5m³–2.5m³ range) depending on tank taper and attachments. For full RAS system integration, coordinated loading with other components like bio-media, pumps, and control boxes is available on request.

Lead Time

• Standard stock: 7–10 working days

• Customized dimensions or integrated accessories: 18–25 days

• Large-volume OEM orders: Negotiable, based on production schedule

Shipping Options
FOB Shenzhen or Guangzhou by default. CIF or DDP terms available upon request. Long-term clients often use consolidated shipping with other YUTANK components to reduce freight cost per unit. For certain countries, we offer agent-based coordination for local clearance and last-mile delivery.

Documentation & Support
Commercial invoice, packing list, certificate of origin (Form A, E, FTA, or RCEP as applicable) provided by default. Tank configuration drawings and installation guidelines are included in PDF format for engineering teams.

FAQ – Biological Filtration Tanks for RAS

Q1: What type of bio-media do your tanks support?
Most YUTANK biofiltration tanks are designed to work with floating K1/K3 carriers and structured media like Bio-Balls or Bio-Rings. Each unit comes with perforated media retention screens and optional airlift diffusers if requested. Clients can specify media brand or volume during the ordering process.

Q2: Can I integrate these tanks into an existing RAS layout with limited space?
Yes, most models offer vertical or narrow footprint formats (e.g., 1.5m height x 0.8m diameter) suitable for retrofitting in compact hatcheries. Our team can provide dimensional drawings and assist in layout matching if you share your site plan or existing tank specs.

Q3: How do you ensure bacterial colonization remains stable during transport and installation?
Tanks are shipped empty, but we recommend soaking the bio-media for 48–72 hours post-installation before introducing fish. For farms reusing old media, we advise sanitization with low-concentration potassium permanganate followed by seeding with nitrifying cultures. Guidelines included.

Q4: What’s the expected replacement cycle for your biological filtration tanks?
The PP or HDPE tank body has a service life of 8–12 years depending on UV exposure and chemical contact. Media may need partial replenishment every 2–3 years depending on fouling levels. Aeration diffusers (if included) are typically replaced every 18–24 months in saltwater use.

Q5: Can I order biofilters together with other components like UV, skimmers, and controllers?
Absolutely. YUTANK offers full RAS system integration. You can consolidate orders with drum filters, protein skimmers, oxygen cones, and smart control cabinets. This ensures compatibility and reduces freight cost per unit. Our overseas clients often request full-kit delivery.
