摘要： Gelatinous sludge agglomerations resulting from the clarification of raw water is separated from the raw water and is then treated with lime in an amount required to react with the gelatinous sludge and produce a filterable sludge in water. The filterable sludge is settled in the water carrying the same and is then separated therefrom and passed through filter means to separate solids from liquid.

摘要： An oil recovery process which utilizes chemical precipitation and complexation reactions to remove dissolved organics and silica from waste water streams. The process produces brine suitable for deep well injection and solids suitable for Class II landfill. The treatment process can be used in combination with a concentrator and in addition to producing brine suitable for deep well injection and solids suitable for Class II landfill, the concentrator also produces a clean water stream for reuse. By including a crystallizer for the brine processing the system has zero liquid discharge.

摘要： Hydraulic fracturing produces backflow water that is high in total dissolved solids, hardness and silica. A system to treat backflow water has an electrical separation unit and a reverse osmosis (RO) unit. The electrical separation unit may comprise an electrodialysis device (ED), an electrodialysis reversal (EDR) device or a supercapacitive desalination (SCD) device, or a combination thereof. The electrical separation unit may be combined with a precipitation unit and reduces the TDS and hardness of the backflow water. The RO unit reduces the silica concentration of the backflow water. A pre-treatment unit may further condition backflow water treated in the electrical separation unit to inhibit fouling in the RO unit. The treated backflow water may be suitable for reuse in hydraulic fracturing or discharge.

摘要： A process for treating hot, pressurized geothermal brine in a liquid-vapor phase separator comprises contacting the brine in the separator with between about 0.2 and about 1.5 parts per million of a defoaming agent so as to substantially reduce the amount of foaming in the separator caused, in part, by steam bubbling through the brine. The preferred defoaming agents are polyglycols having molecular weights between about 1000 and about 2500, those agents having molecular weights below about 1000 being too volatile and those above about 2500 being too difficult to solubilize in the brine. If the separator comprises a draft tube-type flash crystallizer in which silica-rich geothermal brine is contacted with a seed material onto which silica from the brine deposits, the process additionally includes establishing and maintaining a brine level in the crystallizer causing circulation of the brine at a rate substantially reducing the rate of silicious scaling of inner walls of the crystallizer which would result in the absence of brine circulation, the established and maintained brine level being such that in the absence of the defoaming agent, excessive amounts of brine in the form of foam would be carried over into steam discharged from the crystallizer. In preexisting separators in which a design steam production rate cannot be attained because of brine foaming, the addition of a defoaming agent by the present process may enable steam production at a rate greater than the design rate.
摘要翻译：用于在液 - 气相分离器中处理热的，加压的地热盐水的方法包括使分离器中的盐水与每百万份消泡剂接触约0.2至约1.5份，以便基本上减少分离器中的起泡量部分地通过蒸汽通过盐水鼓泡。优选的消泡剂是分子量在约1000至约2500之间的聚二醇，分子量低于约1000的那些试剂太挥发，而高于约2500的那些试剂太难溶解在盐水中。如果分离器包括引流管式闪蒸结晶器，其中富含二氧化硅的地热盐水与来自盐水沉积的二氧化硅的种子材料接触，则该方法还包括建立并保持结晶器中的盐水水平，引起盐水循环以大大降低结晶器内壁的硅质垢的速率，这将导致不存在盐水循环，建立和保持的盐水水平使得在没有消泡剂的情况下，过量的盐水形式的泡沫将被转移到从结晶器排出的蒸汽中。在由于盐水发泡而不能实现设计蒸汽生产率的预先存在的分离器中，通过本方法添加消泡剂可以使蒸汽以大于设计速率的速率生产。
