The storm and pond waters are expected to contain dirt, dust and wood <br /> particles. Some of these solids will settle in the Flow Equalization <br /> Basin. Other smaller particles will be removed by the strainer and filters. <br /> Solids collected will be pumped to the Sludge Drying Beds. In these beds, <br /> the solids will be dewatered and tested for the presence of hazardous <br /> constituents. The dewatered solids will be removed from the beds and <br /> disposed of at an appropriate disposal site. <br /> After filtration, the water will pass through the ion exchange equipment. <br /> The ion exchange equipment consists of three ion exchangers, equipment for <br /> regeneration of the exchangers, and necessary controls. The ion exchangers <br /> are the "heart" of the treatment plant and are described in the previous <br /> section. The treated water then is discharged in compliance with the NPDES <br /> discharge permit. <br /> Recovery and Regeneration Flow <br /> The stripped wood treating chemicals captured during the regeneration <br /> process, are stored in the Recovery Tank and are recycled into the wood <br /> treating process. Other liquids used to regenerate the resins are captured <br /> in the Neutralization Tanks and are analyzed for pH and content of wood <br /> treating chemicals. If the chemical content is low enough to meet effluent <br /> limitation requirements, the liquids will be neutralized and discharged <br /> with other treated water. If not, the liquids will be neutralized and <br /> drained to the storm water pumping station for additional treatment. The <br /> flow patterns for these process liquids are indicated in Figure 6. <br /> S6 4 <br /> HII <br />
