We have collaborated with the company HEINEKEN ESPAÑA, which is developing various initiatives to reduce its environmental impact. In this context, in order to minimise the contamination of its wastewater and, at the same time, recover valuable compounds contained within it, AINIA carried out a study for the implementation of electrodialysis processes with bipolar membranes at the company’s production plant in the province of Valencia. As a result, a complete treatment system has been designed that will reduce the conductivity of the generated wastewater and enable the recovery of sodium hydroxide at concentrations and quality suitable for reuse within the industry itself.
