Waters located at greater depths usually exhibit high mineral content, which necessitates the use of closed systems, i.e. re-injecting them into the formation after recovering the heat. This significantly reduces investment efficiency owing to the need to drill absorption wells and to perform anti-corrosion and anti-clogging procedures. In this paper, possibilities for the efficient utilisation of cooled geothermal waters are considered, particularly with respect to open or mixed geothermal water installations. Where cooled water desalination technologies are used, this allows the water to be demineralised and used to meet local needs (as drinking water and for leisure purposes). The retentate left as a by-product of the process contains valuable ingredients that can be used for balneological and/or leisure purposes. Thus, the technology for desalinating spent geothermal waters with high mineral content allows improved water management on a local scale and makes it possible to minimise the environmental threat resulting from the need to dump these waters into waterways or surface water bodies and/or inject them into the formation. The paper is concerned with Polish geothermal system and provides information about the parameters of Polish geothermal waters.
深度较大的水域通常矿物质含量较高，这就需要使用封闭系统，即在回收热量后将其重新注入地层。由于需要钻探吸收井以及进行防腐和防堵塞程序，这显著降低了投资效率。本文探讨了高效利用冷却地热海水的可能性，特别是对于开放式或混合式地热海水装置。当使用冷却海水淡化技术时，这使得海水能够脱盐并用于满足当地需求（作为饮用水和用于休闲目的）。作为该过程副产品留下的截留物含有可用于浴疗和/或休闲目的的有价值成分。因此，高矿物质含量的废地热海水淡化技术有助于在当地范围内改善水资源管理，并有可能将因需要将这些海水倾倒入水道或地表水体和/或注入地层而产生的环境威胁降至最低。本文关注波兰的地热系统，并提供有关波兰地热海水参数的信息。
