LDesalination plants are facilities whose purpose is to obtain potable water from sea or brackish water, particularly necessary in countries and geographic zones where there is difficulty in accessing water suitable for consumption. 

As water experts, and aware of this need and the increasing scarcity of water resources, at Tecexsa we have developed a new technology that has made us a worldwide point of reference for physicochemical pre-treatment.

This is our new system, DAF: DESALFLOAT, a novel system that provides an effective solution for desalination.


Urban Waste Waters contain organic and inorganic contaminants – dissolved and suspended – that must be separated for the water to be discharged according to strict environmental regulations. Treatment processes include physicochemical systems, as well as biological processes.

For decades, research efforts and technologies were focused on developing biological treatments. However, there has been growing interest in the past few years in strengthening physicochemical treatment technologies, complementary to biological treatment. Specifically, technologies based on air flotation are the focus of research. 

With our equipment ISOFLOAT and EXAFLOAT, we meet today’s demands, both for primary and for secondary treatment. With tertiary treatment, in addition to DAF systems, we include our Pressure Filters or Continuous Washing.


Conceptually similar to the application of urban waste water, the following segments are of note:

paper: we recover fibres from the inner circuit and discharged water treatment. 

Water: we treat wastewater from the production process, especially pastes and resins, as well as colourants and dyes.

Textile: we treat discharged water from cleaning in the production process, especially from fabric bleaching and dying phases.  

Food and beverages: we treat discharged water from the production process.

Petro-chemical and Hydrocarbons: we treat discharged water with a high oil and fat content.

Chemical: we treat discharged water that requires the elimination of additives, colourants, etc. 

Iron and Steel: we take care of cleaning cooling water, the presence of metals or other elements that are difficult to eliminate in the biological process.

Mining: we recover minerals and prepare discharge water

Our equipment ISOFLOAT and EXAFLOAT allow us to meet primary and secondary treatment demand. With tertiary treatment, in addition to DAF systems, we include our Pressure Filters or Continuous Washing.


Re-use is a critical process to recover water and prevent environmental degradation. It provides a new use other than direct discharge, encouraging industrial, economic and social development, in balance with its exploitation

The paper sector, a clear example of a water-dependent industry, has critical water recovery needs for its production process. This is why, at TECEXSA, we have several projects both from the ISOFLOAT and from the EXAFLOAT lines, particularly adapted to their needs.

Additionally, we have developed the CLEARFLOAT model, which includes a floater and sand filter with sectorial cleaning, so we can offer complete solutions.


Drinking water treatment plants are facilities to obtain potable water from water extracted from rivers, wells, etc.

At Tecexsa, we have a range of specific solutions, tailored to each need, from our circular  ISOFLOAT floaters, to rectangular  EXAFLOAT floaters  and compact plants DRINK WATER PACK.


The purpose of these treatments is to reduce the volume of the contaminating discharge in the controlled dump, and mainly, to eliminate the volatile material. Although initially this may fall under the general Wastewater Treatment process, our equipment acts in its own right in this part of the process.

Thus, our equipment  ISOFLOAT THICKENING both for metallic (IFE) and for Civil Works (IFOCE) are mainly applied to eliminate and concentrate suspended solids. The range of concentration of solids varies, although 5% thickening has been obtained, without chemical additives. The highest limit reached is 12%, with chemical additives.
