    • A process for treating acid mine drainage containing heavy and base metals and soluble contaminants is provided. In one embodiment, at least a metal cation is added to the acid mine drainage at a pre-select pH to form insoluble heavy and base metal complexes. After the removal of the heavy and base metal complexes, the pH is raised to the alkaline range. Following removal of base metal hydroxides and gypsum, membrane filtration is employed to generate a treated membrane permeate having a reduced concentration of heavy and base metals and soluble contaminants, and a membrane reject stream containing a concentrated brine. The concentrated brine is further treated with additional lime and at least an aluminum salt to remove remaining soluble contaminants, thus producing a treated water stream with reduced levels of contaminants. Carbonation with CO2 is employed at the end of the process to neutralize flows and further precipitate residual aluminum and calcium salts.
    • 提供了一种处理含有重金属和贱金属和可溶性污染物的酸性矿井排水的方法。 在一个实施方案中,至少一种金属阳离子以预先选择的pH添加到酸性矿井排水中以形成不溶性重和碱金属络合物。 去除重金属和碱金属络合物后,将pH提高至碱性范围。 在除去碱金属氢氧化物和石膏之后,使用膜过滤产生具有降低的重质和碱金属和可溶性污染物浓度的处理过的膜渗透物,以及含有浓缩盐水的膜排出流。 浓缩的盐水进一步用额外的石灰和至少一种铝盐处理以除去残留的可溶性污染物,从而产生具有降低的污染物水平的处理水流。 在过程结束时采用碳酸化方法中和流动,进一步沉淀出残留的铝和钙盐。

    • The present invention includes a method and system for interactively viewing, tracking, and managing stored inventory, for example, in centralized off-site locations, such as warehouses and shipping/receiving centers. The present invention allows the user to view and track every segment of the shipping history of a product stored in several warehouses, as well as delivery to a final recipient. In one embodiment, identifying information specifying an inventory item is stored in a database, and the identifying information is associated with an inventory listing and a responsible party Once inventory information has been stored, a user can access various features for managing inventory. These features include modifying an inventory item, viewing the history of a shipping order, to generating reports, accessing administrative information, or accessing help information.
    • 本发明包括用于交互地查看,跟踪和管理存储的库存的方法和系统,例如在诸如仓库和运输/接收中心的集中的异地位置。 本发明允许用户查看和跟踪存储在几个仓库中的产品的运输历史的每个部分,以及递送到最终的接收者。 在一个实施例中,将指定清单项目的识别信息存储在数据库中,并且识别信息与库存清单和责任方相关联一旦存储了库存信息,用户可以访问用于管理库存的各种功能。 这些功能包括修改库存项目,查看运输订单的历史记录,生成报告,访问管理信息或访问帮助信息。
