Construction & engineering

Sustainable construction is a complex sector with a lengthy value chain. Desotec offers simple purification solutions for different stages: the remediation of land and groundwater, the treatment of manufacturing air emissions and wastewater, and the purification of emissions from building work. Our filters enable companies to meet limits on volatile organic compounds (VOCs), keeping air quality high and odours low. They also help firms protect our environment by reducing pollution in wastewater and groundwater measured as chemical oxygen demand (COD). Additionally, Desotec filters allows your firm to meet strict limits on specific chemicals with high environmental or health impacts.

The production of paints, coatings, bitumen roofing, insulation materials, and plastics release VOCs. Many of them are odorous, including polyaromatic hydrocarbons (PAH). Emissions may also contain compounds such as benzene that must be removed to protect air quality and the health of site workers. Wastewater from manufacturing and cleaning processes could require purification of chlorinated compounds and traces of process chemicals. Desotec filters are the simple answer. Installation and exchange is easy and swift, requiring no production downtime. As our system is modular, filters may be added or removed as your manufacturing requirements change or legislation is tightened.

At former or current industrial sites, historic leaks and spills may contaminate groundwater and soil. Contaminants include: phenols, e.g., from creosote, persistent organic pollutants (POPs), per- and polyfluoroalkyl substances (PFAS), halogenated hydrocarbons, and chlorinated compounds measured as adsorbable organic halogens (AOX). Desotec’s mobile activated carbon air filters purify vapours released by the thermal treatment of soil. On top of that, our water filters treat pumped-up groundwater, leaving it safe for discharge. Desotec filters have a small footprint, thus fitting into crowded construction sites. They are plug-and-play and may be delivered rapidly when discovering new contaminations, thus preventing any project delay. Being available for rental, they are ideal for temporary remediation projects. Also, no carbon or filtration waste is handled on-site.
