New GAC filter eliminates micro-pollutants with exceptionally high efficiency
A Swiss Medtech company set out to treat its production wastewater to a very high standard while significantly reducing the volume of hazardous waste. To achieve this, the client constructed a pre-treatment plant for industrial wastewater. At the heart of the system, micro-pollutants are adsorbed by three granular activated carbon (GAC) filters connected in series. The filter cartridges are mounted on mobile racks and can be easily replaced when saturated. This allows the industrial wastewater — which is contaminated with biocides and, in some cases, antibiotics — to be treated on site and then safely discharged into the public sewer system for further purification at the municipal wastewater treatment plant.
HOLINGER acted as general planner and process engineering specialist for this technically demanding and multifaceted project.
