Seafood Processing Water Plant

General Details

• Purpose: Provide high-quality water for seafood processing, equipment cleaning, and ice production.
• Water Source: Municipal water, borewell water, or seawater (with desalination).
• Compliance: Meets standards like HACCP, FDA, and ISO 22000 for food safety.

2. Capacity

• Processing Capacity:
  • Small-scale: 5,000–10,000 liters per hour (LPH).
  • Medium-scale: 10,000–50,000 LPH.
  • Large-scale: 50,000–500,000 LPH (industrial plants).

3. Filtration Stages and Technology

Stage 1: Pre-Treatment

• Screening Filters: Removes large particles, sand, and debris.
• Sedimentation Tank: Settles heavier suspended solids.
• Chemical Dosing:
  • Coagulants to remove turbidity.
  • Antiscalants for RO systems.

Stage 2: Filtration

• Sand Filters: Removes sediment, silt, and larger suspended solids.
• Activated Carbon Filters: Eliminates chlorine, organic impurities, and odors.
• Micron Filters: Removes fine particles (1–5 microns).

Stage 3: Desalination (if applicable)

• Reverse Osmosis (RO) System: Removes dissolved salts, heavy metals, and reduces TDS (Total Dissolved Solids).
  • High-pressure pumps for seawater desalination.
• Energy Recovery System (optional): Improves efficiency in seawater RO systems.

Stage 4: Disinfection

• UV Sterilization: Kills bacteria, viruses, and pathogens.
• Ozonation (optional): Ensures odor-free water and additional disinfection.
• Chlorination: Provides residual disinfection in storage tanks.

Stage 5: Post-Treatment (Optional)

• pH Adjustment: Ensures water is neutral and safe for seafood.
• Mineralization Unit: Adds necessary minerals for specific processes.

Ice-Making Water Treatment (Optional)

• Ultra-purified water system to produce food-grade ice for preserving seafood.

4. Technical Specifications

• Power Supply:
  • Voltage: 220–415V AC, 50 Hz (customizable based on location).
• Power Consumption:
  • ~2–10 kW for small-scale plants.
  • ~20–100 kW for larger industrial setups.
• Operating Pressure:
  • Filtration: 2–5 kg/cm².
  • RO: 10–80 kg/cm² (higher for seawater desalination).

5. Material of Construction

• Filter Tanks: FRP (Fiber Reinforced Plastic), Stainless Steel (SS304/316), or HDPE.
• Piping: Food-grade PVC/UPVC/HDPE or Stainless Steel.
• Valves and Fittings: Corrosion-resistant materials suitable for food-grade applications.

6. Control System

• Automation: PLC-based system for monitoring and controlling plant operations.
• Sensors: Real-time monitoring of pH, TDS, pressure, and chlorine levels.
• Alerts: Filter replacement, membrane cleaning, and water quality alarms.

7. Dimensions and Weight

• Plant Size: Dependent on capacity:
  • 5m × 10m for a 50,000 LPH system (varies based on layout).
• Weight: 500–5000 kg, depending on capacity and materials used.
