Exergy’s PURAQ is a state-of-the-art water purification platform based on the principals of electrodionization(EDI) technology to replace commercial and industrial portable exchanges that are currently in use to make on demand DI water for various production and processing needs. The PURAQ systems come equipped with pre-treatment modules for incoming city water purification, as an option. When incoming water contains high levels of TDS, TSS or other contaminants, the system may be modified to handle all incoming fresh water qualities. Systems with or without pre-treatment are specified to deliver the required quality of DI water for customer needs, and specifications.
