Stainless Steel Freshwater Shrimp Aquaculture Nano Bubble Generator

Stainless Steel Freshwater Shrimp Aquaculture Nano Bubble Generator

characteristic

 Micro/nano bubbles have unique charaterisitcs–
 

High Surface Area to Volume – increased contact area for oxygen transfer – high air-water

interface area.
 

Low rise rates – increased time for gas transfer.
 

Negative charge – limits coalescence of bubbles.
 

Self pressurisation of bubbles with decreasing size – increased dissolution.​
 

Compared to bubbles generated by diffusers, microbubble/nano bubbles have 6 times the

surface area and 36 times lower rise rates. Following on from pilot scale evaluations, in both

aquaculture and wastewater treatment sectors, the potential benefits of microbubble

technologies can to be applied in aeration, oxygenation, degassing, MBBR aeration, i.e. a

singular technology for multiple applications within the freshwater aquaculture industry.

Microbubble technology has potential to deliver four-fold increase on Standard Aeration

Efficiency over Oxygen cones.

Introduction
 
A micro-nanobubble technology has attracted much interest in bio-related areas such as
 
bioremediation, aquaculture and plant cultivation. MNBs are superior to macro-bubbles
 
because they have larger interfacial area, higher inner pressure, lower rising velocity in water,
 
long lifetime and high mass transfer efficiency. Also, the generation method of MNBs has an
 
impact on their properties. All these factors will dramatically improve dissolved oxygen supply.
 
Advantage
 
1. Using high-pressure rotary flow transient release technology,high density of micro nano
 
bubble,non-clogging,easy to maintain.
 
2. Functional bubble diameter of 200 nm ~ 50μm , saturated water can be quickly produced
 
with good gas-liquid dissolving effect.
 
3. Stable performance, high efficiency, low noise.
 
4. Wide range of application,such as : waste water /gas treatment aquaculture,agricultural
 
irrigation,bath and so on.
