Applications

We treat water whatever its source and final use. These are the six main families of plants we design, always tailor-made.

Industrial wastewater

We treat industrial effluents so they meet their discharge permit or go back into the process. We combine pretreatment, physical-chemical treatment, aerobic or anaerobic biology and the sludge line.

Example of typical stages

  1. Pretreatment
  2. Equalization
  3. Physical-chemical
  4. Biological
  5. Sludge treatment

Result. Discharge within the permit

Municipal wastewater

We design wastewater treatment plants for municipalities, water boards, residential developments and resorts. We combine pretreatment, primary treatment, biological treatment with nitrogen and phosphorus removal, tertiary treatment and the sludge line, and we prepare the effluent for reuse when the project calls for it.

We design to the legislation of each country. In the European Union, to Directive (EU) 2024/3019 concerning urban wastewater treatment.

Example of typical stages

  1. Pretreatment
  2. Primary settling
  3. Biological N-DN
  4. Secondary settling
  5. Tertiary
  6. Sludge treatment

Result. Effluent fit for discharge or reuse

Process water

Water rarely reaches industry at the quality its process requires. We design plants for feed water, boiler water and demineralized or ultrapure water, seeking the best technical, economic and environmental balance.

Example of typical stages

  1. Filtration
  2. Reverse osmosis
  3. Ion exchange or EDI
  4. Disinfection
  5. Storage tank

Result. Water at the quality each process needs

Water reuse

We reclaim treated wastewater for industrial, urban or agricultural use. It is increasingly necessary in the most water-intensive industries, and it is the path to zero liquid discharge (ZLD).

We design to the legislation of each country. In Spain, to Royal Decree 1085/2024, which approves the water reuse regulation.

Example of typical stages

  1. Treated effluent
  2. Ultrafiltration
  3. Reverse osmosis
  4. Disinfection
  5. Storage tank

Result. Reclaimed water for industrial, urban or agricultural use

Desalination

We turn seawater and brackish water into water fit for drinking, agriculture and industry. Reverse osmosis is the core technology, and we design it together with the intake, the pretreatment, the brine discharge and the product water tank, with options such as blending and energy recovery.

Example of typical stages

  1. Intake
  2. Pretreatment and/or UF
  3. Reverse osmosis
  4. Remineralization
  5. Disinfection
  6. Storage tank

Result. Drinking and irrigation water

Drinking water

We treat water so it can be consumed safely, for drinking and for the food industry. The process depends on the raw water and can combine pretreatment, coagulation and flocculation, settling, filtration, adsorption, membranes, remineralization and disinfection.

We design to the legislation of each country. In Spain, to Royal Decree 3/2023 on the technical and health criteria for drinking water quality.

Example of typical stages

  1. Intake
  2. Physical-chemical
  3. Filtration
  4. Ultrafiltration
  5. Disinfection
  6. Storage tank

Result. Water for human consumption

Industries

Every industry, and every company, uses water differently and produces a different effluent. These are the main industries we serve.
