High Efficiency Compact Dissolved Air Flotation Machine with Automated Control for Wastewater Treatment

Dissolved Air Flotation (DAF) Machine Wastewater Treatment Plant
Zhongqiao Enlightenment DAF Machine overview
Product Overview

Zhongqiao Enlightenment's Dissolved Air Flotation (DAF) Machine is a high-efficiency solid-liquid separation device widely applied as pre-treatment for industrial wastewater streams containing suspended solids, grease, and fine particles. Applications include textile dyeing, food processing, slaughterhouses, aquaculture, and healthcare facilities. The proprietary internal-pump pressure mixing technology delivers compact, reliable, and efficient performance.

Core Technology: Internal Pump Pressure Mixing

Conventional flotation equipment requires separate recirculation pumps and air compressors, resulting in complex structures and high energy consumption. Zhongqiao Enlightenment's DAF machine integrates the air dissolution process directly within the pump body using a specially designed internal pressure chamber, generating uniformly distributed micro-bubbles of 25-40 micrometers. This innovation eliminates the recirculation pump and air compressor entirely.

Working Principle and Process Flow

Wastewater enters the flotation machine where, with flocculants, contaminants coagulate into floc. Pressure-dissolved water releases micro-bubbles that adhere to floc particles, forming bubble-floc aggregates with density lower than water. These aggregates rise to the water surface forming a sludge layer that is automatically scraped into a sludge hopper. Treated clear water exits from the bottom outlet.

Product Features and Technical Specifications
  • Fine Uniform Micro-Bubbles: Bubble diameter 25-40 μm, superior adhesion for fine suspended solids and emulsified oils
  • Ultra-Simple Structure: No recirculation pump, no air compressor. Component count reduced by approximately 40%
  • High Treatment Efficiency: SS removal ≥ 90%; COD removal ≥ 60% with flocculation; grease removal ≥ 95%
  • Automated Control: PLC-controlled automatic sludge skimming, chemical dosing, water level adjustment
  • Compact Footprint: Approximately 30% less floor space than traditional flotation equipment
Key Specifications: Treatment Capacity 5-200 m³/h; Bubble Diameter 25-40 μm; Dissolved Air Pressure 0.3-0.5 MPa; SS Removal ≥ 90%; Power 380V/50Hz three-phase

Typical Application Industries
  • Textile Dyeing and Printing: Efficiently removes dyes, auxiliaries, organics, and suspended solids
  • Food Processing: Treats grease and SS from meat processing, dairy, and starch factories
  • Aquaculture: Rapidly separates fish feces, residual feed, and suspended matter
  • Slaughterhouse: Effectively removes blood, grease, and fine particles
  • Medical Pre-treatment: Assists in removing disinfectants and pharmaceutical residues
