Lewatit®CNP 80 WS是一种弱酸性，大孔，丙烯酸基阳离子交换树脂，用于现代逆流再生系统，具有特殊珠粒尺寸分布。由于它的总量和搅拌能力非常高，优异的化学和机械稳定性以及对渗透冲击的高抗性，它好好用于脱碱。带有强离解阳离子交换剂（Lewatit®MonoPlus S 108）的脱盐装置（例如Lewatit®VWS System）具有更高的再生效率。由于Lewatit®CNP 80 WS只需要低过量的再生酸，因此可以经济在以下应用中使用：使用并流或现代逆流系统运行的工业用水的脱碱，例如， Lewatit®WS系统，Lewatit®LiftbLewatit®多步骤系统或Lewatit冲洗系统。与强酸性阳离子交换树脂例如Lewatit®MonoPlus S 108，用于脱矿物质的去水装置。去除暂时硬度（与碱度相关的硬度）。在去矿化装置（抛光机）下游的单床装置中，去除在流动时以氢氧化物形式存在的阳离子速率高达50米/小时。采用单一过滤装置或与Lewatit®S 1567混合作为抛光剂生产水软化。其钠形式用于从电镀漂洗中去除/提取重金属，如铜，镍和锌pH值的水Lewatit®CNP 80 WS可以与所有传统的离子交换工艺配合使用。对于其他系统有特殊的具有合适的珠尺寸分布的这种树脂的等级。

Lewatit® CNP 80 WS is a weakly acidic, macroporous, acrylic-based cation exchange resin of special bead size distribution used in modern counter-current regenerated systems. Due to its very high total and perating capacity, excellent chemical and mechanical stability together with high resistance to osmotic shock, it is preferable used for dealkalization. The arrangement with strong dissociated cation exchanger (Lewatit® MonoPlus S 108), in demineralization units (e.g. Lewatit® VWS System) leads to higher regeneration efficiency.

As Lewatit® CNP 80 WS only requires a low excess of regenerant acid, it can be economically used in the following applications:

• Dealkalization of industrial water operated with co-current or modern counter-current systems like e.g. Lewatit® WS System, Lewatit® Liftbed System, Lewatit® Multistep System or Lewatit Rinsebed System.

• Removal of temporary hardness (hardness associated with alkalinity).

• In produced water softening as single filter unit or in combination with Lewatit® S 1567 as polisher.

• In its sodium-form for the removal/extraction of heavy metals such as copper, nickel and zinc from electroplating rinse waters at a pH-value Lewatit® CNP 80 WS can be used in conjunction with all conventional ion exchange processes. For other systems there are special grades of this resin with a suitable bead size distribution.

• In a single bed unit downstream from a demineralization unit (polisher) for the removal of cations present as hydroxides at flow rates up to 50 m/h.

• In combination with a strong acidic cation exchange resin, e.g. Lewatit® MonoPlus S 108, in a decationization unit for the demineralisation of water.
