Integrated water treatment in a one-stage oxidative-adsorptive process to degrade and remove harmful substances (OxFloc)
Date du début: 1 sept. 2013, Date de fin: 31 déc. 2015 PROJET  TERMINÉ 

Current costs for industrial wastewater treatment in Europe are already an economic burden and are expected to rise. With 4.5 billion Euros spent each year this is restricting the growth of the European production sector, especially in water scarce areas where there is a pressing need to reuse water. OxFloc aims to reduce treatment costs by at least 30% while offering modular installation and application engineering at a price below comparable State-of-Art processes. OxFloc systems will have a quantified superior environmental benefit, a smaller plant footprint, lower operation costs and enable 100% water recycling as they work without salt-carrying chemicals. Not all industrial wastewaters are the same, but many carry a mix of toxic chemicals, non-biodegradable components and hormones e.g. tenside, flame resistants, pharmaceuticals, pesticides and heavy metals. Therefore, industrial effluents need significant treatment before they can be discharged to a municipal waste water treatment plant. Typically the pollutants exist with suspended particles, requiring a clearing pretreatment which increases cost and energy consumption of current treatments. Our system solves this problem by combining particle removal and adsorption with advanced oxidation. Our OxFloc system is a one-stage combined flocculation-oxidation process that needs no chemicals because electrolytic production of the iron catalyst, as well as hydrogen peroxide, takes place in the reactor itself. It is an integrated system capable of degrading and removing both dissolved and suspended harmful substances from industrial wastewaters using only electrical energy. It will be fully compatible with power from renewable energy sources, conventional supply or from smart power grids balancing demand and offer of electrical energy. It can be utilised by over 265,000 SME-businesses in Europe for water treatment and recovery making them more sustainable and competitive.
