THE Flotation unit for wastewater treatment It is a piece of equipment widely used in industrial water and wastewater treatment systems. This technology is especially efficient at removing... oils, greases, suspended solids and other contaminants present in liquid streams originating from industrial processes.
The systems of flotation in wastewater treatment They are applied in various industry segments, such as Oil and gas, petrochemicals, refineries, mining, pulp and paper, chemical industry, and industrial wastewater treatment.In these applications, the flotation unit plays a fundamental role in separating contaminants before the final stage of disposal, reuse, or reinjection of the treated water.
The functioning of a Flotation unit for wastewater treatment It is based on the principle of flotation, in which small bubbles of air or gas are generated inside the equipment and come into contact with the contaminant particles present in the liquid.
These microbubbles adhere to droplets of oil, grease and solid particles, reducing its relative density. As a consequence, the contaminants rise rapidly to the surface of the flotation tank, forming a layer that can be removed by collection systems.
The flotation process generally involves the following steps:
This process allows for efficient separation between the liquid phase and the contaminants present in the industrial effluent.
You Flotation units used in wastewater treatment They are designed to achieve high levels of efficiency in removing contaminants.
Depending on the characteristics of the effluent and the technology used, flotation systems can deliver excellent results in removing:
In many cases, flotation systems are able to significantly reduce the levels of contaminants present in the effluent, allowing compliance with the regulations. Environmental requirements for the disposal or reuse of treated water..
For this reason, the Flotation unit for wastewater treatment It is frequently used as an essential step in industrial treatment plants.
There are different technologies of Industrial flotation units for wastewater treatment., developed to meet different types of processes and flow rates.
Among the main types used in the industry are:
Each technology has specific design characteristics and separation efficiency, and is selected according to the type of effluent, operating flow rate, and treatment requirements.
THE TSL Engineering, Maintenance and Environment has experience in the operation, maintenance and technical support of different systems of Flotation processes applied to the treatment of industrial wastewater and oily water..
Among the equipment used, high-efficiency flotation systems stand out, designed for demanding industrial operations.
One example is Cyclosep type vertical compact floater, which integrates different separation stages into a single piece of equipment, including centrifugal separation, coalescing media, and microbubble flotation to maximize the removal of oil and solids present in contaminated water.

These systems use Special flotation pumps (DGF – Dissolved Gas Flotation pumps) responsible for generating microbubbles that promote the efficient separation between water and contaminants.
You Flotation units for wastewater treatment They are used in various industrial operations involving contaminated liquid streams.
Among the main applications, the following stand out:
In these applications, flotation devices contribute to improving the efficiency of the treatment system and ensuring the environmental compliance of industrial operations.
THE TSL Engineering, Maintenance and Environment has extensive experience in performing services related to Industrial wastewater treatment and flotation systems used in the oil and gas industry..
The company provides technical support for treatment systems, performing activities such as:
With a specialized technical team and high-performance equipment, TSL contributes to to restore the operational efficiency of flotation systems, ensuring better performance in wastewater treatment and greater reliability of industrial units.
In an industrial wastewater treatment plant, the flotation unit sits after primary separation, which removes free oil and coarse solids, and before the polishing stages or biological treatment. This is where dispersed and emulsified oil and fine solids are removed. A flotation unit with low efficiency overloads every downstream stage.
That is why, when the oil and grease content at the outlet starts to rise, the cause is usually in the flotation unit: accumulated sludge, fouling of the internals, failure in microbubble generation or inadequate chemical dosing.
TSL performs chemical and mechanical cleaning of flotation units, removal of oily sludge and accumulated solids, hydroblasting of the internals and support for maintenance shutdowns, with disposal of the removed waste. The goal is to restore the equipment to its design separation efficiency.
Depending on the stream being treated, see oily wastewater treatment, oily water treatment and produced water treatment. To compare flotation technologies, see dissolved air flotation (DAF) unit.
Oil and grease (TOG), suspended solids, colloidal particles and industrial oily residues.
In separating the contaminants before the final stage of discharge, reuse or reinjection of the treated water.
Oil and gas, petrochemicals, refineries, mining, pulp and paper, the chemical industry and industrial wastewater treatment plants.
Chemical cleaning of flotation units, removal of oily sludge and accumulated solids, internal hydroblasting, maintenance and recovery of operational efficiency, support for maintenance shutdowns and proper disposal of the waste removed.
