Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain desalination technologies and how they work, describe applications and notable facilities with sources, present energy, cost and environmental considerations with attribution, and support water policy and engineering questions at a general level.

A separation process that removes salts and minerals from seawater or brackish water to produce fresh water for drinking, agriculture and industry, by membrane methods such as reverse osmosis and by thermal methods such as multi-stage flash, multiple-effect distillation and humidification, with variants powered by solar, geothermal or low-temperature heat; desalination is used at scale in water-scarce regions such as the Middle East, Israel, Australia and California, with considerations of energy use, cost and brine disposal.

What it is for: Producing fresh water from saline water.

It can be explain technologies; describe applications and facilities; present considerations; support policy questions.

Distinguishing features

Salt removal

Energy intensity

Brine by-product

Scale from household to city

What it looks like

Plants with membrane racks or thermal units, intakes and outfalls.

How it is recognised

Removes salt from water

Membrane or thermal

Water treatment removes contaminants but not necessarily salt; softening removes hardness
