Dissolved Gas Flotation Service

High Performance in Wastewater Treatment

The system of Dissolved Gas Flotation Dissolved Gas Flotation (DGF) represents the state of the art in the separation of oils and suspended solids in complex industrial effluents. This technology is essential to ensure that the disposal or reuse of water in refining units, terminals, and platforms is in full compliance with current stringent environmental regulations.

THE TSL Engineering and Services It stands out in the global market for providing flotation systems integrated with advanced technology pumps, designed to operate in continuous regimes and environments with extremely high technical demands, such as the Oil and Gas sector.

Tradition and Numbers that Prove Authority

THE TSL It has one of the most solid track records in the Brazilian market for supplying technologies for oily water treatment, with milestones that attest to its technical reliability:

Solid Experience: Operating since the 1980s, the company has accumulated decades of expertise in developing engineering solutions for the industrial and environmental sectors.
History of Success: TSL is proud to have more than 35 flotation systems in operation, serving major exploration and refining units;
Leadership in Critical Projects: Extensive portfolio of supplies for large operators, with emphasis on the implementation of flotation and oily water treatment units in highly complex operational environments.

Microbubble Technology and Materials Engineering

The heart of an efficient system of Dissolved Gas Flotation It lies in the quality of the mixture between the gas and the liquid. TSL It uses highly reliable components that provide unique competitive advantages:

High-Precision Microbubble Generation: Through rotors with a dual function, the system promotes the dissolution of gas in the water stream, generating microbubbles with controlled diameters (≥ 1µ). This maximizes the contact area and flotation speed of the oil particles;
World-Class Metallurgy: Our systems and pumps are designed with materials that are highly resistant to corrosion and erosion. Depending on the aggressiveness of the fluid, we use high-grade metallurgy such as stainless steel, duplex, and super duplex, ideal for water with high chloride content.
Sealed and Secure Systems: Designed to operate in a completely sealed manner, the equipment eliminates the emission of odors and aerosols, ensuring a safe working environment in compliance with occupational health standards;
High Performance Offshore: Technology adapted with wave-absorbing systems, maintaining performance even under rocking movements in marine units.

Strategic Advantages of the TSL DGF System

1. TOG (Total Oil and Grease) Efficiency: Reaching purity levels that allow for safe disposal or reuse in industrial processes.
2. High Flow Capacity: Customized projects to support large processing volumes, adapting to the scale of your industrial plant.

Frequently asked questions

What is Dissolved Gas Flotation (DGF)?

It is flotation by dissolved gas: the gas is dissolved into the water and released as microbubbles that carry oils and suspended solids to the surface. It is used for complex industrial effluents from refining units, terminals and platforms.

How does TSL's DGF system generate the microbubbles?

Through dual-function rotors that dissolve the gas into the water stream and generate microbubbles of controlled diameter (from 1 µm). This increases the contact area and the flotation speed of the oil particles.

Which materials are used in dissolved gas flotation equipment?

Depending on how aggressive the fluid is, the systems and pumps use stainless steel, Duplex and Super Duplex, materials suited to water with high chloride content.

Does the DGF system work on offshore vessels and units?

Yes. The technology includes wave-absorbing systems that maintain performance even with the motion of floating units.

Does the flotation system emit odors or aerosols?

No. The equipment operates fully sealed, which eliminates the emission of odors and aerosols into the work environment.
