Abstract: A fluid treatment apparatus comprising a tank containing a bed of at least one fluid treatment medium, a distributor plate separating the bed from an end portion of the tank, and an inert medium comprising amorphous particles having a harmonic mean diameter from 2.5 to 250 mm and a density from 0.57 to 0.998 cm3/g. The volume of the end portion containing inert medium is from 25 to 95% of the total volume of the end portion.

Abstract: Novel water softening products and methods of treating hard water are provided. The products comprise a salt and a metal chelating agent. The products are useful for regenerating ion exchange material in a water softening system and providing softened water containing both sodium and potassium ions, while having dramatically increased efficiencies over prior art products.

Abstract: An ion exchange apparatus in which granular exchanger material is deposited to a level above a horizontal drainage for the regeneration medium solution of an ascending countercurrent regeneration process and considerably below an upper liquid connection. A timing generator that divides the regeneration phase into flow segments and rest segments is provided. To reduce the amount of regeneration medium required while changing only slightly the flow resistance and improving the exchanger efficiency, the concentration of the regeneration medium solution is increased to a value that without the timing generator leads to poor utilization of a given amount of regeneration medium. An additional layer of exchanger material excluded from the regeneration process is deposited to a level considerably above the drainage. An intermediate layer of exchanger material extends to a level considerably below the drainage, adjoins the additional layer, and can be mixed with the latter via a mixing device. As constituents of the mixing device, backwash nozzles are provided at the lower boundary of the intermediate layer. These backwash nozzles are distributed over a plurality of nozzle heads that are supplied via the drainage and spacers that extend downwardly from the drainage.
Abstract translation: 一种离子交换装置，其中颗粒交换器材料沉积到上升逆流再生过程的再生介质溶液的水平排水口以上并且明显低于上部液体连接的水平面上方。 提供了将再生相分成流动段和静止段的定时发生器。 为了减少所需的再生介质的量，仅改变流动阻力并提高交换效率，再生介质溶液的浓度增加到没有定时发生器导致给定量的再生介质的利用不良的值。 从再生过程排除的另外一层换热器材料沉积到排水面以上的水平。 交换器材料的中间层延伸到明显低于排水口的水平，邻接附加层，并且可以通过混合装置与后者混合。 作为混合装置的组成部分，反冲洗喷嘴设置在中间层的下边界处。 这些回洗喷嘴分布在经由从排水口向下延伸的排水和间隔件供给的多个喷嘴头上。
