Technology

Engineering and patents of TECEXSA products.

Technical Capability

Design, manufacture, integration and commissioning.

Knowledge

More than 50 years of experience inherited from TECEXSA.

Flexibility

We tailor each solution to the actual operating environment.

About Us

Water deserves a real engineering company.

At ACTIVA INGENIEROS, S.L. we were born to give back to the water sector what it should never have lost: technical rigour. We are not commercial. We are engineers.

We are engineers

We are not commercial. And we believe that the success of each plant begins in the detail drawing, not in the catalog.

They trust us

Companies in the industrial, energy and public sectors looking for technical rigor, regulatory compliance and real support on site.

Each environment has its own water. Each water, its engineering company.

En ACTIVA INGENIEROS, S.L. we work in the main areas of the water cycle, with solutions adapted to each sector

Business areas

At ACTIVA INGENIEROS, S.L. we work in the main areas of the water cycle, with solutions adapted to each sector:

List of our most outstanding designs

ISOFLOAT

ISOFLOAT is a circular DAF system with radial laminar distribution

EXAFLOAT

EXAFLOAT is a rectangular DAF with a high surface load

CLEARFLOAT

integra un DAF tipo ISOFLOAT con un filtro de Integrates an ISOFLOAT type DAF with a continuously washable circumferential sand filter

FLOC-ST

Compact Plant for Excavation Work Water

CHEMIX

Automatic system for the preparation of solid or emulsion flocculant

PCW

Compact containerized plant for drinking water treatment

Because the difference is not in the equipment, but in how they fit together

R&D+i

At ACTIVA INGENIEROS, we are solution facilitators, so the R&D+i activity we develop is an intrinsic part of our company philosophy

ASR System

Our new ASR saturator, which is at its highest efficiency, culminates our efforts with this goal. It automatically adjusts the pressurization through a loop with the PLC, ensuring that MICRObubbles are obtained at constant size. Thanks to this, MICRObubbles:
  • adhere to the floc more quickly and effectively
  • increase the residence time of the microbubble inside the float
  • are evenly distributed along the flotation surface
  • generate more consistent sludge
