About Activa Ingenieros, S.L.

Water Treatment Engineering

Activa Ingenieros, S.L. is a water-engineering company based in Mungia, Biscay, designing, manufacturing, integrating, and commissioning water-treatment and reuse systems. The company describes itself as a technical rather than sales-led team: it assesses raw-water conditions and regulatory requirements before proposing a solution, rather than starting with standard catalog equipment.

Areas of Work

  • Desalination, including high-efficiency dissolved-air flotation (DAF) systems for large flow rates
  • Municipal wastewater: design and optimization of wastewater-treatment plants and tertiary treatment
  • Industrial wastewater: physical-chemical processes and customized technologies
  • Water reuse: advanced treatment and control systems
  • Water supply: safe drinking-water treatment and clarification
  • Industrial design: detailed engineering, integration, and technical support

Proprietary Products and Technology

The company sells in-house-designed equipment, several products of which are patented, for dissolved-air flotation (DAF) and compact water treatment:

  • ISOFLOAT: Circular DAF system with radial laminar distribution.
  • EXAFLOAT: Rectangular DAF system with a high surface loading rate.
  • CLEARFLOAT: Combines an ISOFLOAT-type DAF system with a circumferential sand filter that backwashes continuously.
  • ASR (Air Saturation Reactor): Saturator that automatically adjusts pressurization through a PLC control loop to produce consistently sized microbubbles.
  • ADS (Self-cleaning Depressurization System).
  • DESAND: Grit-removal system.
  • FLOC-ST: Compact treatment plant for water from excavation sites.
  • CHEMIX: Automatic system for preparing solid or emulsion flocculants.
  • PCW: Containerized compact drinking-water treatment plant.

Experience and Approach

Activa Ingenieros reports more than 30 years of combined experience in water-treatment system design, physical-chemical processes, and DAF flotation, building on expertise inherited from TECEXSA. Its work covers the full water cycle—design, supply, integration, commissioning, and maintenance—through an integrated engineering approach and proprietary high-performance DAF microbubble technology. The company says it conducts R&D&I and has validated projects in complex operating environments.

Customers

The company serves industrial, energy, and public-sector organizations, as well as technical leaders seeking engineering expertise, regulatory compliance, and on-site support.
