Equipment Description:
I. Working Principle
1. Pressurized Dissolved Air
Air at a pressure of 0.35-0.45 MPa passes through a dissolver and
mixes with water, forming supersaturated dissolved air water. The
filler layer inside the dissolver enhances gas-liquid contact
efficiency.
2. Decompression Release
The dissolved air water enters a normal pressure environment
through a releaser, instantly releasing microbubbles with a
diameter of 20-50 μm. These bubbles evenly adhere to the surface of
suspended matter, reducing its density to less than that of water.
3. Flotation Separation
The bubble-suspended matter complex rapidly rises to form a scum
layer. The clear water below is discharged through a collection
pipe, with a portion of it being recycled for the dissolved air
water cycle.
4. Scum Removal
A scum scraper removes the surface scum into a sludge tank,
reducing the water content to ≤90%, completing solid-liquid
separation.
II. Technical Features
1. High-Efficiency Separation
Removal rates of 85%-95% are achieved for oily wastewater, fibrous
suspended matter, and algae. 2. Energy-Saving Design
The modular structure reduces footprint by 30% and reduces
dissolved air energy consumption by 20% compared to traditional
equipment.
3. Stable Operation
The system features uniform microbubble distribution and strong
resistance to water quality fluctuations, making it suitable for
wastewater with high shock loads.
4. Environmental Compatibility
The integrated paint mist treatment unit ensures emissions comply
with GB 37824-2024 standards.
III. Applications
Industrial Wastewater: Separation of suspended solids and grease in
the papermaking, printing and dyeing, and food processing
industries.
Municipal Wastewater: Concentration of sludge after biological
treatment and purification of low-turbidity, high-color water.
Main structures and components:
I. Core Structure
1. Dissolved Air System
Dissolved Air Tank: A high-pressure vessel (operating pressure
0.35-0.45 MPa) with an internal packing layer to enhance gas-liquid
mixing efficiency.
Gas-Liquid Mixing Pump/Air Compressor: Mixes air with return water
under pressure to create supersaturated dissolved air water. Some
designs use a gas-liquid mixing pump instead of a traditional air
compressor, simplifying the air flow piping.
Water Pump: Provides a high-pressure water source. Some models use
return water to produce dissolved air water to reduce energy
consumption.
2. Release System
Release: A core component responsible for instantaneously releasing
dissolved air water at reduced pressure, generating microbubbles of
20-50 μm. Circular flotation systems typically place the releaser
in the center of the tank to ensure even distribution of bubbles.
Distributor (conical structure): Assists the releaser in evenly
mixing dissolved air water with wastewater, improving impurity
capture efficiency. 3. Flotation Tank
Contact Zone: This is where wastewater and dissolved air water mix,
allowing suspended solids and air bubbles to combine.
Separation Zone: This allows scum to float and the clean water to
separate. The tank is typically made of stainless steel or
fiberglass for corrosion resistance.
Case Types: These include horizontal flow (rectangular), circular
(such as the QFY type), and upflow (vertical flow).
4. Sludge Scraping System
Sludge Scraper: This is a chain or rotary design with a scraping
efficiency of ≥95% and a sludge moisture content of ≤90%.
Sludge Tank and Sludge Discharge Pipe: This collects and discharges
sludge and settled sludge.
II. Auxiliary Systems
1. Control System
PLC Module: This automatically adjusts the dissolved air pressure,
reflux ratio (typically 20-40%), and scraping frequency, supporting
unattended operation. 2. Chemical Dosing Device
Coagulant Dosing Unit: Adds chemicals such as PAC and PAM to
enhance the binding of flocs and bubbles, improving pollutant
removal efficiency.
3. Clean Water Circulation System
Return Pipeline: Recycles treated clean water (approximately 30%)
for dissolved air water production, reducing water consumption.
III. Typical Configuration Differences
| Models | Structural Features | Applicable Scenarios |
| Horizontal Flow | Rectangular housing, separate dissolved air system and scraper design | Large-volume industrial wastewater treatment |
| Circular/QFY | Central releaser + conical distributor, highly integrated | Small- to medium-scale oily/fibrous wastewater treatment |
| Upflow | Vertical water flow path, highly concentrated separation zone | Pretreatment of wastewater with high suspended solids concentrations |
Features:
1.High cost performance: Based on the customer's product
positioning and development strategy, and with economic
affordability as the foundation, we achieve the best cost
performance.
2.The advanced and meticulous design concept of the equipment,
