Micro-bubbles for Fish & Shrimp Farming

Micro-bubbles for Aquaculture
Micro-bubbles for Aquaculture

Micro-bubble technology provides a comprehensive solution for the aquaculture industry. By breaking down air or oxygen into ultra-fine bubbles, it penetrates all layers of the fish pond, stabilizing water quality and significantly increasing dissolved oxygen levels. This results in healthier fish and shrimp with faster growth rates.

As these bubbles collapse, they help remove bottom sludge and harmful substances while effectively inhibiting bacteria and parasites. Whether in shallow or deep-water ponds, the system works uniformly to maintain water clarity. The equipment features a large-orifice design, making it resistant to clogging and suitable for long-term, stable operation.

Whether farming fish or shrimp, this technology enhances survival rates and breeding efficiency. We also provide professional consulting for micro-bubble applications, helping you build a high-efficiency, eco-friendly smart aquaculture environment.

Smart Oxygenation & Water Quality Management in Aquaculture

Aquaculture Microbubble

Smart Oxygenation • Water Quality Management
System Evaluation Solutions

Venturi Natural Air Intake

Draws in air naturally using a Venturi valve, combined with system flow rates, pressure, and piping conditions to form an optimal gas-liquid mixing setup.

Pond Bottom Microbubble Coverage

Microbubbles disperse from the bottom of the pond, helping enhance water body mixing and gas-liquid contact efficiency; coverage varies based on pond shape, depth, flow rate, and layout.

Support Oxygenation & Water Quality

Can be applied to recirculating aquaculture systems to help improve dissolved oxygen and circulation management conditions, with subsequent adjustments made according to field data.

Custom System Configurations

Tailors the microbubble system configurations and test methods according to fish species, stocking density, pond shape, water depth, existing piping, and power conditions.

* Actual results will vary depending on fish species, stocking density, water quality, water temperature, pond shape, flow rate, pressure, equipment configuration, and on-site management methods. On-site evaluation and testing are highly recommended.

Microbubble Aquaculture Circulation & Technology Principles | ERDEN

Breaking Traditional Surface Aeration Mindsets
Establishing Circulation & Dissolved Oxygen Management Across All Water Layers

Common Limitations of Traditional Paddlewheels & Aerators

  • Large bubbles rise rapidly and tend to gather near the surface of the water.
  • Aeration and agitation are often concentrated in localized areas; deep water still requires evaluation based on pond structure and layout.
  • Water temperature, DO levels, and circulation conditions may vary due to water depth, stocking density, and seasonal changes.
  • Operational efficiency, power consumption, and maintenance needs vary by equipment type and on-site management methods.

Configuration Features of Micro/Nano Bubble Systems

  • Uses Venturi valves and microbubble modules to disperse air as microfine bubbles throughout the water.
  • Microfine bubbles greatly increase gas-liquid contact area and prolong the bubble retention time in water.
  • Allows planning pond bottom air release and circulation paths based on pond shape, depth, flow rate, pressure, and piping.
  • Helps enhance water body mixing and dissolved oxygen management; actual performance must be verified via field testing.
Comparison schematic between traditional surface aeration and AM248B bottom microbubble circulation
Diagram shows the configuration concepts for surface aeration and bottom microbubble circulation; actual coverage and circulation depend on field conditions.

What are Microbubbles?
Bubble Size & Gas-Liquid Contact Principles

Size comparison of macrobubbles, microbubbles, and ultra-fine bubbles

01 | Microfine Bubble Dispersion

Smaller bubble size increases the gas-liquid contact surface in water; actual bubble size and distribution are affected by equipment, flow rate, pressure, and water conditions.

02 | Water Mixing Conditions

Combined with bottom air release and proper circulation layout, it helps create more uniform mixing and flow conditions in the water body.

03 | Continuous Recirculation Management

The system can be planned according to stocking density, pond shape, water depth, and existing equipment for subsequent dissolved oxygen and recirculating water management.

* The actual results of microbubble systems will vary based on fish species, stocking density, water temperature, water quality, pond shape, water depth, flow rate, pressure, equipment configuration, and site management. It is recommended to perform a site assessment before installation and use field DO and water quality data as adjustment criteria.

Water Temp vs. Dissolved Oxygen Saturation | ERDEN

Water Temp vs. Dissolved Oxygen Saturation Reference

Dissolved oxygen (DO) in water varies with water temperature and atmospheric pressure.
The higher the water temp, the lower the theoretical saturated DO limit.

Current Measurement Conditions

Water Temp 28.7°C
Dissolved Oxygen (DO) 7.0 mg/L
7.0 ÷ 7.75 × 100% ≈ 90.3%
Currently ~90% Saturation

What is 100% Saturation?

The amount of oxygen that can dissolve in water when the water body and air reach equilibrium under specific water temperature, salinity, and atmospheric pressure. This serves as the 100% saturated DO reference value under those conditions.

Interpreting DO Saturation Levels

Saturation is calculated as "measured DO ÷ 100% saturated DO under the same conditions × 100%." Factors such as water temperature, altitude/atmospheric pressure, salinity, and water quality must be considered together to interpret measurements correctly.

Interpret readings alongside fish/shrimp activity, feeding patterns, and piping gasps.

☾

Monitor Nighttime Changes

Nighttime and early morning are critical periods where aquaculture farms must pay close attention to DO.

↗

Integrate Water Quality Management

Should be evaluated in combination with water temperature, feeding rate, stocking density, and recirculation conditions.

↻

Establish Measurement Records

Regularly logging DO changes helps in subsequently adjusting equipment settings and management practices.

Using this test condition as an example: with water temperature at 28.7°C and DO at 7.0 mg/L, the calculated saturation is ~90.3%. Actual management should still be based on on-site water quality, stocking density, and continuous measurement data.

* The listed values are reference data under standard atmospheric pressure. Differences in instruments, altitude, atmospheric pressure, salinity, and water quality may cause variations. Confirming the consistency of data sources and on-site measurements is recommended before official reference.

Bubble Type & Distribution Predominantly large bubbles rising rapidly to the surface layer of the water. Microfine Bubble Dispersion Combined with gas-liquid mixing and pond bottom air release, bubble distribution can be designed based on system requirements.
Gas-Liquid Contact Conditions Rapid bubble rise results in shorter contact times; scope depends on equipment type. Increased Contact Area Microfine bubbles multiply the gas-liquid contact area; actual effects are determined by flow rates, pressure, and water conditions.
Water Body Circulation Planning Mainly focuses on surface agitation and localized aeration. Bottom Circulation Layout Circulation paths and bottom air release locations can be designed based on pond shape, depth, and piping.
Maintenance & Management Varies depending on equipment type, frequency of use, and site management practices. Module count and piping are adjustable to need; regular inspection of pumps, pipes, and microbubble modules is advised.
System Power Consumption Actual consumption depends on equipment horsepower, running time, and local conditions. Consumption can be evaluated based on pump selection, module count, and operating settings, benchmarked against on-site measurements.

Stage 2 | Flow Splitting

Uses manifold fittings to split the flow into different branches, allowing each area to be equipped with microbubble modules as needed.

Stage 3 | Pipe Size & Flow Balancing

Pipe diameter, branch run lengths, and module count influence flow rates and pressure; configurations should be balanced via field testing.

Stage 4 | Internal Circulation Analysis
