Schwartzwalder Water Treatment Plant (SWTP) Operations and Maintenance The purpose of this Request for Proposals is to obtain competitive proposals from qualified individuals and firms to remove hazardous and radioactive substances from the environment through the operation and maintenance of the Schwartzwalder Water Treatment Plant (SWTP). The SWTP treats the mine pool water. Water is pumped from the mine workings to the surface with the objective that the mine pool does not exceed an elevation of one hundred and fifty (150) feet below the Steve Level. The SWTP key processes to treat water include pre-filtering, followed by reverse osmosis (RO) and a finishing polish of the water via ion exchange (IX). Three reagents are utilized during the process. First, an anti-scale is injected into the raw mine influent just prior to the prefilters to help reduce scaling of the RO's membranes. A second reagent, barium chloride, is injected into the concentrate stream coming from the ROs to precipitate radium after it is injected underground. And finally, sodium hydroxide is injected into the discharge water to adjust the water pH to within the permit-defined range of 6.5-9.0 before it can flow to Ralston Creek. The Contractor shall operate and maintain the SWTP in a safe, effective and cost-efficient manner and shall develop and implement the plans and procedures necessary to achieve this goal.
