RAS生物过滤池 – 稳定的生物过滤解决方案 | YUTANK

特征

• 多区域内部设计
  分段式腔室可划分专门的曝气、沉降和生物膜生长区域。即使在进料负荷变化的情况下，这种结构也能稳定氨到亚硝酸盐的转化率。

• 带排水口的斜底
  每个水箱均配备精密角度底座和中央集水槽出口。这支持日常污泥冲洗——这是大多数国际 RAS 运营中的标准程序。

• 兼容 MBBR 和静态介质
  从浮动式K1到结构化固定床，我们的槽体结构支持多种介质类型，并具有均匀的流动动力学。我们将相应地校准喷嘴布置和流量。

• 重型材料选项
  根据农场水体化学特性，提供耐化学腐蚀的PP或海洋级HDPE材质。壁厚、加强筋和抗紫外线涂层均可定制。

• 轻松改造现有系统
  进出水管配件可与传统储罐匹配。尤其适合全球客户从混凝土或玻璃纤维储罐升级。

• 服务舱口和媒体访问端口
  超大顶部端口可快速检查培养基并清洁生物膜。可选配网篮，方便在收获或清洗储罐时安全排出培养基。

• 稳定的生物群落锚定
  内部流动挡板可最大限度地减少死角，同时最大限度地保留氧气——这是长期维持高密度生物群落的关键。

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.
