"Water is the driving force of all nature"
Lack of water- the importance of preserving it
2.2 billion people live without access to safe drinking water
Can we achieve it?
The goal of Sustainable Development No. 6: Water and Sanitation for All By 2030
Achieving universal and equitable access to safe drinking water at an affordable price for all
Improving water quality by reducing pollution, eliminating spills and minimizing chemical emissions
Anyone can make a change
Even at home you can make a change in preserving water
Take shorter showers,
Water your lawn only when it needs it, fix leak, save water whenever possible, recycle water.
Converte salt water into drinkable water
Desalination is a process that carries away mineral components from saline water.
The most common desalination processes are distillation and reverse osmosis.
Provides accessible drinking water.
High costs to build and operate.
Why desalination is bad for the environment?
Desalination can raise fossil fuel reliance and augment emissions. Aggravate climate change if renewable energy sources are not freshwater production. Desalination surface water inputs stand a considerable hazard to marine life.
a gas that absorbs and ejects radiant energy
the action of purifying a liquid by a process of heating and cooling.
It imitates the natural water cycle, where the sun heats seawater sufficiently for evaporation to happen. After evaporation, the water steam is squeezed onto a perfect surface. There are two kinds of solar desalination; the first type uses to transform solar energy to electrical energy to power desalination, and the second type converts solar energy to heat. It is known as solar thermal powered desalination.
It relates to the production of electric current at the junction of two substances exposed to light.
It employs a temperature distinction across a membrane to evaporate steam from a brine solution and compact pure water on the colder side. The membrane structure can include a considerable consequence on efficiency and durability. A study discovered that a membrane made through co-axial electrospinning of PVDF-HFP and silica aerogel could purify 99.99% of salt after constant 30-day use.
Our use of water can help reduce floods, droughts, scarcity, and pollution, as well as combat climate change
