Outsourced Water Treatment Provides Lower TOC And Higher Purity For Nuclear Power Plant By Michael Reyes, Crown Solutions Co., LLC
Crown Solutions Co., LLC, a Veolia Water Solutions & Technologies company, was contacted by a Southeast Nuclear Utility to develop a competitive solution to design, build, install, operate, and maintain two new 400-gallon-per-minute (GPM) ultra-high-purity demineralized water plants to replace their internally operated, 25+ year old, demineralized water plant at two separate stations.
The proposed MACT standards for both utilities and industrial boilers focus on removal of HCl in the presence of SO2. While many sites use sodium sorbents for removal of HCl, and many others for removing SO2 or other acid gases, there is a paucity of publicly available data on the removal of HCl in the presence of SO2, especially in the case of coal-fired power generation.
Mixed bed ion exchange is often used to polish reverse osmosis (RO) permeate in many industrial water systems. This process has been utilized for several years and it is well known that the management of the dissolved carbon dioxide (CO2) in the water is critical for an efficient operation.
