The highly alkaline decomposed slurry and salt solution in the Decomposition Tank will be pumped to a filter press (see Figure 1.2-3) for physical separation (see Appendix 1-C Process Flow Diagrams). The filter press is designed with ventilation hoods that connect to the hygiene exhaust system as discussed in Section 1.2.6. The mercuric oxide filter cake will drop down the filter press chutes and be collected in drums and will be retorted. The filtrate will be discharged into a neutralization tank (Waste Solution Treatment Tank) where hydrochloric acid (HCl) will be added to neutralize the alkaline waste solution into salt (NaCl) as per the following reaction: NaOH (aq) + HCl (aq) NaCl (aq) + H2O (l) A reagent (TMT 15, or functional equivalent) will be added to the Waste Solution Treatment Tank, which will precipitate dissolved mercury and assist with the settling of other heavy metals in a conical tank (Waste Solution Settling Tank) downstream in the waste solution treatment circuit. The waste solution treatment circuit is discussed in more detail in Section 1.2.7. The reagent material will be stored in the original vendor provided containers in the plant spaces. All tanks as well as the calomel feed preparation station will be maintained under slight negative pressure by localized ventilation systems which are discussed in Section 1.2.6. All tanks in the calomel caustic leach circuit will be covered. PMR RCRA Permit Application, Dry Hills Facility Page 22 JBR Environmental Consultants, Inc. | HATCH March 2013
