本文综述了荷兰球团反应器软化水的各种方法中使用的化学品和工艺。重点介绍了一种新的反应器概念，其基础是在含有氢氧化钠的种子材料上结晶。在长期、全面的操作中，这一概念提供了低成本的软化，并消除了固体处理的问题。（本文于1983年6月5日至9日在内华达州拉斯维加斯举行的AWWA 1983年年度会议上发表。）包括16个参考文献、表格和图表。

This paper reviews the chemicals and processes applied in various methods of water softening with pellet reactors in the Netherlands. Emphasis is given to a new reactor concept based on crystallization on a seeding material with sodium hydroxide. During long-term,full-scale operations, this concept has provided low-cost softening and eliminated problems with solids disposal. (This paper was presented at the AWWA 1983 Annual Conference, Las Vegas, Nevada, June 5-9, 1983.) Includes 16 references, tables, figures.
