Marine Sewage Treatment Plants System Overview
The Dissolved Air Flotation Marine Sewage Treatment Plants system is an efficient water treatment technology designed to remove:
✔ Free-floating & emulsified oils
✔ Heavy metals (dissolved)
✔ Soaps & surfactants
✔ Industrial/organic contaminants
Widely adopted in China for its high efficiency, low energy consumption, and easy maintenance, this system sets the standard for modern flotation clarification.
How It Works
-
Air Dissolution Stage
-
Water is pressurized and saturated with air
-
Upon release into the flotation tank (at atmospheric pressure), microbubbles (20-50μm) form
-
-
Contaminant Removal
-
Bubbles attach to suspended solids/oil droplets
-
Rapid floatation carries pollutants to the surface
-
-
Separation Enhancement
-
Lamella (parallel plate) modules increase effective surface area
-
Improves settling efficiency by 300%+ vs conventional DAF
-
-
Sludge Harvesting
-
Automated scraper removes floated sludge layer
-
