摘要： Undissociated, non-toxic, organic compounds and inorganic silicate compounds which are polymerized in the presence of acid phosphate salts added to the solutions having from one-third to two-fifths of ocean salt concentrations maintain the osmotic pressure of the solutions at the equivalent of the osmotic pressure of natural ocean water and provide media for aquariums which will support both fresh water and salt water fish.

摘要： A water stream containing a water-soluble sulfite compound is treated in order to reduce its total sulfur content while minimizing the formation of sulfate byproducts by the steps of: (a) converting the sulfite compound contained in the water stream to the corresponding thiosulfate compound; (b) catalytically reacting the resulting thiosulfate compound with hydrogen at reduction conditions selected to produce the corresponding sulfide compound; and thereafter (c) stripping hydrogen sulfide from an effluent stream from step (b) to form a substantially sulfate-free treated water stream which is substantially reduced in total sulfur content relative to the input water stream. Principal utility of this treatment procedure is associated with the regeneration of a sulfite-containing absorbent stream which is commonly produced by contacting a flue gas stream containing sulfur dioxide with a suitable aqueous absorbent stream containing an alkaline reagent.
摘要翻译：处理含有水溶性亚硫酸盐化合物的水流，以减少其总硫含量，同时使硫酸盐副产物的形成最小化，步骤为：（a）将水流中所含的亚硫酸盐化合物转化为相应的硫代硫酸盐化合物; （b）将所得硫代硫酸盐化合物与氢气在还原条件下催化反应，选择生成相应的硫化物; 然后（c）从步骤（b）的流出物流中除去硫化氢，以形成基本上无硫酸盐的处理水流，其相对于输入水流基本上降低总硫含量。这种处理方法的主要用途与含亚硫酸盐的吸收剂流的再生有关，通常通过使含有二氧化硫的烟道气与含有碱性试剂的合适的吸收水接触而产生。

摘要： Sewage treatment in which sewage is passed to a tertiary treatment plant from an activated sludge plant, said tertiary treatment including the step of intimately mixing lime and particular polyamines with the effluent from the secondary clarifier. The polyamines catalyze the reduction of phosphate in the sewage by the lime, thereby lowering the quantity of lime required to produce water having a satisfactory phosphate level.

摘要： Improved apparatus is disclosed for treating waste water with a chemical. The apparatus is self-contained and may be moved from site to site for use on a permanent, semi-permanent or temporary basis as needed. It is strong, durable and light weight in construction, operates automatically or semi-automatically, and does not require a full-time operator. An outside power supply is not needed as the apparatus is powered by the water being treated. The apparatus is especially useful in treating acidic mine water with a chemical having a basic reaction before it is discharged into a stream or sewer, but other types of waste water may be treated.
