We’re a Spanish Engineering Company specialist in urban and industrial wastewater treatments with our groundbreaking VRT® 4.0 technology: an eco-sustainable wastewater treatment solution, with very high economic, environmental and social benefits & returns.
We design, build, commission and operate our tailor-made VRT® 4.0 Wastewater Treatment Plants worldwide.
The technology: VRT® 4.0 technology is a continuous aerobic biological wastewater treatment, suitable for any kind of biodegradable effluent, even those with very high BOD and COD contents.
With over 200 VRT® WWTPs in 6 countries since 1993, our state-of-the-art VRT® 4.0 combines principles & benefits of time-tested technologies with special CFD modelling and simulation tools, guaranteeing  > 98% pollutants+nutrients removal efficiency (N & P incl.) plus 100% chemical-free process.
We offer our DsM2 model: an innovative “on-site” low-cost high-profit wastewater treatment solution, which maximizes wastewater value while minimizes worhtless by-products.
VRT® 4.0 technology’s benefits (compared with CAS technologies):
CAPEX savings, up to 75%:
•	Up to 90% less surface area required,
•	Reuse of existing wastewater treatment infrastructures.
•	Up to 70% less time required for building and commissioning of VRT® WWTPs

OPEX savings, up to 50%:
•	Up to 65% less electricity consumption.
•	Up to 95% less final biosolids production (sludge).
•	Up to 70% less staff and maintenance expenses.

Environmental and social benefits:
•	Irrelevant landscape impact (underground layout, 100% odours and nuisance free).
•	Maximizes treated wastewaters reuse and recycle, with UF & RO.
•	Minimizes related water and wastewater costs (discharge fees).
•	Up to 95% less Greenhouse Gases emissions.
•	Minimizes penalty fines and sanctions due to failure to comply with Environmental Laws and Regulations.
•	Tax benefits (Green/R&D investment), to be applied at client’s best scenario.
•	EU, Nationtal, Regional and Local subsidies availability.
