What AGUASIGMA does

AGUASIGMA is a privately held Spanish environmental engineering company that designs, builds, commissions, and maintains customized wastewater treatment plants for industrial customers. Its customers include manufacturers in consumer goods, food and beverage, safety equipment, chemicals, and other process industries, as well as biogas and anaerobic-digestion operators. The company reports wholly owned operating entities in Spain, Mexico, and France, more than 800 completed projects across 25+ countries, and three manufacturing plants.

Core treatment technologies include Membrane Bioreactors (MBR, including NDN and aeration variants), Sequential Biological Reactors (SBR), an aeration/FBR system integrated with DAF, Moving Bed Biological Reactors (MBBR), and anaerobic reactors (RANC). MBR combines biological treatment with membrane filtration, while DAF separates solids and flocs; SMARTDAF provides automated monitoring and adjustment of coagulation-flocculation, pH, and clarification. AGUASIGMA also offers digestate treatment and valorization, SIGMALAB wastewater analysis, and after-sales training, preventive maintenance, repairs, and component replacement.

AGUASIGMA sells through direct B2B enterprise field sales, with commercial agents following up on inquiries within 48 hours. Its model combines process engineering, fabrication, plant construction, commissioning, laboratory analysis, and lifecycle services; pricing is quote-based and determined by plant specifications, treatment requirements, capacity, and selected technologies, with the supplied pricing record describing multi-year contract cadence. The company reports 5,000+ m² of production and assembly space, and an April 2026 announcement described a new pavilion intended to increase operational area to 10,000 m².
