Dissolved Air Flotation (DAF) Machine
Product Overview
The DAF machine is a high-efficiency water treatment equipment designed for industrial wastewater, municipal sewage, and hospital sewage treatment applications. This advanced system achieves rapid solid-liquid separation by utilizing micro-bubbles to adsorb and remove suspended solids from water.
The core technology employs small or micro-bubbles to make impurities float to the water surface, making it particularly effective for treating fine particles with specific gravity close to water that are difficult to remove through conventional sedimentation methods.
Product Applications
In water supply and drainage pretreatment systems, most raw water contains light suspended particles that challenge traditional treatment methods. The DAF machine excels in removing these challenging contaminants:
- Algae from lakes, reservoirs, and river systems
- Plant residues and fine colloidal impurities
- Dye particles in printing and dyeing industry wastewater
- Short fibers from paper-making and chemical fiber production
- Micro-droplets of oil and organic solvents in refining and chemical processes
- Heavy metals from electroplating, pickling, and electrocoating wastewater
These light particles share the characteristic of having specific gravity very close to water, making traditional sedimentation methods inefficient, particularly during winter's low-temperature conditions when coagulation and hydraulic performance deteriorate.
Technology Advantages
For flocs that resist conventional settling, forced sedimentation proves inefficient. The DAF machine introduces a revolutionary approach by artificially introducing bubbles that adhere to flocs, significantly reducing their overall density. Driven by bubble buoyancy, flocs are forced upward, enabling rapid solid-liquid separation.
Dissolved air flotation technology represents a significant advancement over gravity sedimentation methods, opening new possibilities in solid-liquid separation technology for modern water treatment applications.
