Ozone/AOP - Pilot Installation Sustainable Water Use in the Chemical Industry
The AquaFit4use project aims at a more sustainable use of water in the main water consuming industries.
Through development and implementation of new, reliable and cost-effective technologies, tools and methods, a far-going closure of the water cycle in these industries is foreseen. Consequently, the intake of fresh water and the disposal of wastewater will be reduced significantly as will the burden imposed by this on the environment. | Pilot plant - technical data | » Flow: 0.7 - 5 m³/h » Max. ozone production: 1 kg/h » Max. energy consumption: 40 KW » Oxygen is required as feed gas. » Space required (container): 3 m * 6 m (20’-container) » H2O2-dosing station up to 90 g H2O2 per m3 water » Defoamer-dosing station Ozone/AOP - Pilot Installation Sustainable Water Use in the Chemical Industry Ozone/AOP- Pilot installation at Perstorp AB/Sweden: | Case Study - Chemical Industry | Goal: COD reduction in final wastewater effluent for water reuse in cooling tower; COD below 100 mg/l required. 1. Existing effluent from treatment plant at Perstorp AB 2. Effluent of pilot Membrane-Bio-Reactor Treatment: Ozone treatment (O3-dosage: 0 - 700 mgO3/m3) Ozone-H2O2 (AOP) (same range, surplus of H2O2) | COMPETITIVE ADVANTAGES | Even non biodegradable contaminants, that couldn’t be degraded in the WWTP, were reduced. Persistent COD can be reduced below COD = 100 mg/l by combining Ozone and H2O2. Water quality is now sufficient for being reused as cooling tower water R&D Application, ITT Water & Wastewater Herford GmbH M. Bromen, Dr. J. Mielcke, J.
