Réservoirs de collecte d'eau pour systèmes d'aquaculture et de traitement des eaux usées | YUTANK

Caractéristiques

• Conception modulaire pour l'intégration de plusieurs réservoirs
  Compatible avec les installations RAS nécessitant un retour d'eau centralisé ou distribué. Les sorties latérales ou inférieures peuvent être positionnées selon l'architecture de la boucle d'écoulement.

• Construction robuste en PP ou FRP
  Adaptés aux environnements d'eau douce et d'eau de mer, nos modèles avec revêtement FRP offrent une résistance chimique renforcée contre la saumure et les désinfectants.

• Chambres d'admission inférieures renforcées
  Les structures internes à cône ou à chicane guident le flux entrant tout en minimisant les turbulences. Cela réduit le reflux des microbulles et empêche l'accumulation de boues à la sortie.

• Options d'interface de bride personnalisées
  Compatibilité des brides en PVC, PEHD ou acier inoxydable pour les tuyauteries d'entrée/sortie. Le choix des joints peut être adapté aux normes de plomberie du pays du client.

• Accès par le haut pour l'entretien et l'inspection
  Accès à large ouverture ou regards scellés pour une inspection interne rapide, un nettoyage ou la modernisation de vannes supplémentaires si nécessaire.

• Déflecteurs de contrôle de débit anti-surtension
  Particulièrement utile dans les systèmes à débit de pompe variable. Les chicanes amortissent les pics d'afflux d'eau pour éviter les chocs de pression dans les UV, les biofiltres et les chambres de pompe.

• Capteurs de niveau intégrés en option
  Pour les utilisateurs disposant de systèmes RAS intelligents, les réservoirs peuvent être livrés avec des modules de détection de niveau d'eau à ultrasons ou à flotteur installés en usine.

Order Fulfillment

Packaging & Protection
All tanks are packaged using export-grade wrapping—multi-layer stretch film with edge guards for surface integrity. For bulk orders or fragile tank types (e.g., large-diameter PP or FRP units), reinforced wooden crates and pallet bases are applied to prevent deformation during cross-border transport. UV protection covers are optionally included for open-yard storage before installation.

Logistics & Transport
Units are typically consolidated in 20ft or 40ft HQ containers depending on the quantity and tank height. Volume-optimized stacking is used for cylindrical models, with nested placement to reduce CBM. Shorter tanks (under 1000L) may be packed vertically to increase load efficiency. All shipments comply with international freight standards for aquaculture-grade plastics and water systems.

Lead Time & Production Capacity
For standard sizes (500–1500L), the lead time averages 12–15 working days after deposit confirmation. Custom-capacity tanks or those with non-standard fittings (e.g., multi-inlet flange layouts or integrated sensor housing) may require 18–25 days. Peak season orders are handled via rolling production and early-slot reservations.

Delivery & Documentation
All deliveries include commercial invoice, packing list, container load plan, and if needed, Certificate of Origin (Form E, Form A, or RCEP). CE compliance declaration and food-grade material certificate are included by default. OEM labeling and custom logo branding are supported upon prior confirmation.

Frequently Asked Questions

Clarifications Sourced from Real Procurement Calls and RAS Design Reviews

1. How are your collection tanks typically integrated into a RAS layout?
They're usually placed right after the mechanical filtration or drum filter, acting as a temporary buffer before water enters the biofilter. Some farms place them slightly sunken to allow gravity return. We've seen this especially in older hatcheries being upgraded with modern piping.

2. Are these tanks pre-molded or welded on demand?
Depends on the size and shape. Smaller circular tanks (<3m diameter) are often pre-formed using rotational molding. Larger rectangular or custom footprint tanks are hot-air welded on site or pre-assembled in panels and sealed at the client facility. Our team has done both for European and Southeast Asian projects.

3. What’s the standard outlet configuration? Can I get side discharge instead of bottom?
Standard units come with a DN100 or DN150 bottom drain, but side discharge can be added on request—common in retrofits where floor drilling is not allowed. We’ve shipped multiple units with dual outlets for farms running split filtration lines.

4. Do you offer baffled designs to manage flow turbulence inside the tank?
Yes. We can include internal partitions, deflectors, or mesh screens to slow incoming velocity and settle fine solids. One of our clients in Saudi Arabia used a baffled collection tank to handle inconsistent return flows from multiple raceways.

5. How do you pack large tanks for export shipping?
We disassemble the side walls and stack panels flat-packed when possible. For one-piece tanks, we build steel-frame cradles with impact buffers and anti-UV stretch wrap. Labeling is done according to ISPM-15 and marine export requirements. Cranes or forklifts are usually needed at port of entry.

6. Can I get a quote including freight and clearance to my farm location?
Yes. Provide your port or final delivery city, and we’ll quote CIF or DDP terms. For repeat clients, we also handle split container loads if they're ordering filter equipment or skimmers at the same time.

7. What if I need matching lids, overflow outlets, or sensor ports?
Not a problem. We fabricate tank covers (full or partial), flange ports for ultrasonic level sensors, and custom overflow elbows with screen guards. All accessories can be pre-mounted before shipment if specified during order.

FAQ（Frequently Asked Questions）

Q1: How do I size a protein skimmer for my RAS system?
A: Sizing depends on daily feed input and system turnover. A rule of thumb is 1 m³/h skimming capacity per 100–150 grams of daily feed. For intensive farms with heavy bio-loads, higher ratios may be required.

Q2: Can I use your skimmer with ozone safely?
A: Yes. Our standard models are ozone-compatible. For prolonged use, we recommend units with titanium venturi and ozone-resistant O-rings. Let us know your ozone dosage during inquiry.

Q3: What's the maintenance cycle like?
A: We recommend daily draining of the foam collection cup and bi-weekly cleaning of the reaction chamber. All parts are accessible without tools, which reduces service time.

Q4: Is it suitable for marine fish larvae systems?
A: Absolutely. Fine-tuned bubble production makes our skimmers ideal for sensitive species and hatchery environments. They remove organics before ammonia conversion, preserving water quality during early-stage rearing.

Q5: Can I customize inlet/outlet configurations?
A: Yes. We offer flexible plumbing configurations, including left/right side inlets, bottom discharge, and vertical top-return piping. CAD installation drawings available on request.
