23-3 Waste Water

Have you ever constructed a natural gas/oil fired electric generating facility of the size and magnitude of the CREC whose water treatment process was designed to utilize mobile, trailer mounted demineralization systems as a permanent component of the pro

Invenergy has not constructed a natural gas/oil fired electric generating facility with the same exact design features as proposed for CREC as posed by this question. Water treatment processes are unique features of nearly every electric generating facility. Invenergy has constructed a number of facilities with similar design features for the treatment of process water.

As stated in Invenergy’s Response to the Town’s Data Request No. 22-30, Invenergy utilizes the mobile demineralizer trailers at our Cannon Falls, MN, St. Clair, Ontario, Spindle Hill, CO and Ector County, TX facilities and has used them on a temporary basis at other facilities, such as Invenergy’s facilities in Nelson, Illinois and Grays Harbor, Washington State.

The water savings technologies identified under the Water Supply Plan are conventional water treatment technologies that have been employed at many power plants and industrial facilities in one form of another for many years.  In this application, the water saving technologies are not unique nor are they new.  The water saving technology that will provide the most significant benefit to the reduction in water use and wastewater reduction at CREC is the use of Ion Exchange Resins in the form of mobile demineralization trailers and some simple industrial filtration systems. 

GE Mobile Water Inc. is one of the vendors that supplies mobile demineralizer services, and a letter from GE Mobile Water that provides additional information on the breadth of their services was submitted to the Energy Facility Siting Board on February 14, 2017 as an attachment to Invenergy’s Responses to the Town’s 22nd Set of Data Requests.
