Читать книгу Introduction to Desalination - Louis Theodore - Страница 20

The following summary observations can be made related to water, seawater desalination, and water treatment in general.

1 Water demand at both the national and international levels is increasing at a faster rate than originally realized.

2 Water demand at both the national and international levels is increasing at a faster rate than population growth.

3 There is indeed growing water scarcity.

4 One approach to solving this water scarcity problem is to develop and/or find new sources of water.

5 Nonconventional water sources will become more attractive in the future.

6 Water conservation measures should be expanded in the future.

7 Seawater and brackish groundwater are nonconventional water sources serving as feedstock for desalination processes.

8 Poor seawater quality can limit RO applications but generally does not have as great an effect on evaporation and crystallization processes.

9 Desalination processes featured evaporation in earlier times, while RO is generally the process of choice today.

10 The increasing demand for potable water will ensure that improvements in current technologies and development of new approaches for potable water production will continue to develop in the future.
