21-7 Water
Manufacturer’s information was included in Invenergy’s revised Water Supply Plan, filed with the Board on January 11, 2017.
The Clear River Energy Center (“CREC”) will utilize mobile demineralizer trailer systems to produce the high quality demineralized water needed. Mobile demineralizer trailer systems have been used for many years in many industries because they produce a high quality demineralized water product, do not rely on facility personnel for their operation, do not require the storage or handling of chemicals on site for their regeneration and do not produce wastewater that must be treated or discharged on site.
Mobile demineralizer trailer systems utilize ion exchange resins that have the chemical capacity to remove dissolved minerals and salts present in the water supply, producing a high quality demineralized water product.
The mobile demineralizer trailers, once exhausted, will be removed from the site by trucks and returned to the suppliers’ regeneration station where the units will be regenerated.
As a result, no chemicals will need to be delivered, stored or used at the CREC for the regeneration of the trailer mounted demineralizer systems since the trailers will be regenerated at the suppliers’ facility and not at the CREC.
Section 2.2.1 (a) of the Water Supply Plan provides additional details on the mobile demineralizer trailer systems and Appendix B provides brochures from two service providers of these types of systems.
