Horizontal Flow Dissolved Air Flotation Machine Equipment Introduction
The horizontal flow dissolved air flotation machine is one of the most widely used solid-liquid separation equipment in the Wastewater treatment industry. It generates micro-bubbles through the dissolved air system to adsorb low-density pollutants such as suspended solids, grease, colloids and algae in wastewater, making them float to the water surface to form scum, thereby realizing separation of clean water and pollutants.
The main body adopts a horizontal rectangular tank structure with horizontal water flow. Featuring moderate floor space, stable operation and high treatment efficiency, it serves as the core pretreatment equipment for Wastewater treatment in printing and dyeing, slaughtering, food, breeding, chemical, municipal and other industries.
Working Principle of Horizontal Flow Dissolved Air Flotation Machine
Dissolved Air System
Clean water is pressurized by a dissolved air pump / air compressor and dissolved air tank, dissolving air into water to form high-pressure saturated dissolved air water.
Instant Air Release
The dissolved air water is suddenly decompressed through the releaser, releasing a large number of fine bubbles with a diameter of 20-50μm, which are uniform, stable and highly adhesive.
Bubble Adsorption & Floating
Micro-bubbles fully contact and adsorb suspended solids, floating oil, algae and fibers in Wastewater, forming gas-solid-liquid three-phase mixture with greatly reduced overall density.
Solid-Liquid Separation
Bubble groups adsorbed with pollutants quickly float to the water surface to form a scum layer; clean water sinks and flows out from the bottom water collection pipe. The slag scraper automatically scrapes scum into the slag tank for discharge, completing solid-liquid separation.
System Advantages
• High separation efficiency: SS removal rate 85%-99%, oil removal rate 80%-95%, excellent effect on low specific gravity pollutants.
• Fine and uniform micro-bubbles: Small bubble diameter, even distribution, strong adsorption capacity, not easy to break with stable treatment effect.
• Smooth operation & low noise: Horizontal flow structure ensures stable water flow without impact, suitable for 24-hour continuous operation.
• Small footprint & simple structure: Integrated design for easy installation, fewer supporting facilities and low maintenance.
• High automation: Equipped with PLC automatic control to realize automatic dissolved air generation, slag scraping, sludge discharge and protection.
• Wide application range: Capable of treating high-turbidity, high-oil, high-fiber and high-organic wastewater with strong impact load resistance.
• Low investment & operating cost: Less chemical dosage, low energy consumption and simple operation with good long-term economic performance.
Application Fields
• Food processing wastewater: Fried food, meat products, bean products, beverage and starch wastewater.
• Slaughter & breeding wastewater: Pig, chicken and cattle farm Wastewater for removing blood dirt, grease and manure suspended solids.
• Printing & textile wastewater: Removal of dyes, sizing agents, fibers, chroma and suspended solids.
• Papermaking & tannery wastewater: Removal of pulp fibers, fur colloids and protein pollutants.
• Petrochemical wastewater: Demulsification and oil removal of oily wastewater, emulsion and cutting fluid wastewater.
• Municipal Wastewater: Pretreatment of Wastewater plants, algae removal, suspended solid removal and initial COD reduction.
• Electroplating & coating wastewater: Removal of heavy metal suspended solids and phosphating residue.
• River & landscape water: Water body algae removal, turbidity reduction, purification and water quality improvement.
