Cavitation Flotation System Components

Advanced wastewater treatment equipment utilizing cavitation technology for efficient oil-water separation

1. Cavitation Generator

This is the core component that generates the cavitation effect. Its special structural design creates a localized low-pressure environment as the water flows through it.

Common forms include Venturi tubes or specialized nozzles
Creates pressure drop causing dissolved gases to release and form microbubbles
Structural precision directly impacts cavitation effectiveness
Key component for achieving microbubble generation

2. Water Flow Diversion and Mixing Structure

This is responsible for guiding the wastewater flow path within the equipment, ensuring even water distribution and sufficient contact with the bubbles.

Uses deflectors or baffles to adjust water flow velocity and direction
Extends wastewater's residence time in the reaction zone
Increases probability of collision between bubbles and oil
Prevents water short-circuits and ensures uniform reaction efficiency

3. Bubble Dispersion and Stabilization System

Comprising a bubble cutting device or porous media, this system performs secondary dispersion on bubbles generated by cavitation.

Ensures uniform bubble size and dense distribution
Some systems equipped with bubble stabilizer dosing device
Maintains bubble stability and prevents premature fusion or collapse
Optimizes bubble characteristics and enhances oil capture

4. Scum Separation and Collection Component

This component includes a sedimentation tank and scum scraping equipment for removing floated contaminants.

Sedimentation tank provides stable, still space for bubble flotation
Scraper or skimmer moves slowly to collect scum
Some equipment features tilted plates or weirs
Enhances solid-liquid separation and scum removal efficiency

5. Control System and Auxiliary Devices

Comprising sensors and regulators, these devices monitor parameters and maintain stable operation.

Monitors parameters such as water flow rate and pressure in real time
Includes inlet water pretreatment unit to remove large impurities
Chemical dosing system adds coagulants or conditioning agents
Ensures long-term stable operation and optimized treatment results

System Integration

The cavitation flotation system integrates these five components to create an efficient wastewater treatment solution. Through precise engineering and intelligent control, it achieves high removal rates of oils and suspended solids while maintaining energy efficiency and operational stability.
