    摘要： A method and apparatus is provided for treating water with already-slaked lime to arrive at a lime slurry that is in a solution or suspension, and delivering the thus treated water to a separating device which separates grit particles therefrom, to recover a high quality lime/water solution or suspension. An automated system controls the addition of lime and water to a lime mixing vessel.
    An acid wash system is provided which comprises an automated method and apparatus for removing scale buildup, for delivering an acid wash solution to the lime mixing vessel, the lime slurry holding tank and/or the delivery system, or any of them, thereby dissolving the scale buildup.

    摘要： An apparatus, method and system is provided for treating sewage sludge by dewatering the sewage sludge, heating the sewage sludge being treated to destroy pathogens, and then reducing volatile solids in the sewage sludge being treated through biochemical decomposition to produce a treated biosolids product that meets government regulations for pathogen reduction and vector attraction reduction.

    摘要： Treated sewage sludge containing a flocculant is discharged from bottom of a bin, with the discharge being facilitated by heating sloped walls of the bin an amount sufficient to increase the ability of the sludge to slide along sloped bin walls. The flocculant in the sludge includes a polymeric material which, when heated to a sufficient temperature effects a phase separation of the polymeric material from water, decreasing the viscosity of the polymeric material, facilitating its sliding along the sloped walls. The heating of the polymeric material in the flocculant enables the sloped walls of the bin to be flatter than they would otherwise be, allowing an enhanced volume of sludge to be present in the bin. A programmable logic computer controls the provision of heat to the sloped walls, as well as controlling an openable closure at the bottom of the bin and/or controlling the rotation of a displacement device in the bin.

    摘要翻译： 含有絮凝剂的处理污水污泥从垃圾箱的底部排出，通过加热箱的倾斜墙壁来提高排放量，足以增加污泥沿倾斜箱壁滑动的能力。 污泥中的絮凝剂包括聚合材料，当加热到足够的温度时，聚合材料与水的相分离会降低聚合物材料的粘度，有助于其沿着倾斜的壁滑动。 絮凝剂中的聚合材料的加热使得箱体的倾斜壁比其它方式更平坦，允许在箱中存在增加的污泥体积。 可编程逻辑计算机控制向倾斜壁提供热量，以及控制箱底部的可打开的封闭件和/或控制料仓中的移动装置的旋转。

    摘要： A sewage sludge silo is provided, having a central discharge arm for discharging sludge via a central discharge opening, by means of the discharge arm sweeping across a preferably sloped silo floor, with the discharge arm having upper and lower ends, with the lower end extending forward of the upper end in transverse generally vertical cross-section, as the discharge arm moves in a forward direction across the silo floor. The silo floor can be of multi-layer construction, with one of the layers being molded to facilitate a sloped configuration for the silo floor. The movement of a silo discharge arm can be computer controlled to adjust the speed of the discharge arm to maintain a predetermined or substantially constant rate of discharge of sludge from the silo, with such control being facilitated by appropriate sensor mechanisms.

    摘要： A lime stabilization system and method is provided in which thickened liquid sludge and lime are separately delivered, under controlled conditions, to a reaction tank and mixed therein to a predetermined pH, controlled via a programmable logic computer. The weight of liquid sludge in the reaction tank is controlled from the computer via load cells that measure the weight of such liquid sludge in the reaction tank. The computer monitors the amount of liquid sludge and lime delivered to the reaction tank, for mixing therein to a desired pH, for a predetermined amount of time, and the resultant mix is discharged from the reaction tank, to a holding tank, for return to the land.

    摘要： An apparatus, method and system is provided for treating sewage sludge by heating the same in a container to drive off pathogens and/or pasteurize the sewage sludge while the material is tumbled in the container and with moisture gases being) evaporated therefrom and drawn off from the container. After treatment the treated sludge is discharged from the container. There is provided at least one weight-responsive member on which the container is mounted, and a control is provided connected to the one or more weight-responsive member whereby the solids content of the treated material can be determined by measuring the difference in weight of material in the container, before and after moisture is drawn off from the material and prior to its discharge from the drum. The control is preferably effected by means of a computer.
