Electro coagulation for water recycling

In a H2020 project electro coagulation for water recycling in the textile industry has been investigated. Water can be reused after ultrafiltration and reverse osmosis. The technology works well, but the produced sludge and brine need to be discharged and that can hamper the feasibility and business case. In the perspective of a circular economy, the brine and sludge resulting from water re-use technology could be further valorised....

Making the textile industry future proof - ISPT

Making the textile industry future proof Global freshwater availability is under permanent stress. There is a serious need for ‘future-proofing’ the industry with respect to water usage, particularly for the textile industry. After all, dyeing and printing processes require considerable amounts of fresh water and produce large and often very polluted wastewater streams. The EColoRO concept offers a solution that includes reclaiming 70% of the wastewater that can be reused in the textile manufacturing process. EColoRO Depending on the local conditions, the current situation is that waste water is treated on-site by the textile company and then discharged to the environment, or it is supplied to the municipal wastewater treatment plant (with or without a pre-treatment by the company). The Consortium for Electro Coagulation for Water Recycling in the Textile Industry (ECWRTI) has charted the prospects of the innovative EColoRO concept for extensive wastewater re-use in textile industry. It offers a solution to treat the wastewater of textile industry with a minimal use of chemicals and energy. By doing so, nearly 70% of the reclaimed wastewater can be reused in the textile manufacturing process. Technology The core of the concept is formed by Electro Coagulation, an additive-free process to remove the majority of all pollutants, colorants...
