What Are Home Made Reverse Osmosis Sap Systems?

There is a vast amount of water on earth. However, over 97% of it is too salty for human use and only a small part of the rest is easily accessible in rivers, lakes or groundwater. The available supplies of fresh water are subject to danger due to growing population, climate change, droughts etc.

As water becomes scarcer, people start finding several ways to secure their water supplies. Many countries of the world have enormous possibilities to use water more efficiently, and that would be cheaper than other filtration systems. Home made reverse osmosis sap systems are one such possibility.

Home made reverse osmosis sap system are used to turn sea water into a drinkable form.

Keeping in view the process of osmosis, scientists discovered that osmosis could be reversed by applying pressure to the more concentrated solution, causing water molecules to disperse through the membrane and leave behind more highly concentrated salt water.

In order to consider the movement of waters, the partition between the two compartments and the force caused by the externally applied pressure are given importance so that the solute cannot move from areas of high pressure to areas of low pressure, because the membrane is not porous to it.

Only water can move in this way. When the effect of the outward applied pressure is more than that of the absorption difference, all of the water will move from area of high concentration to the area of low concentration, and in this way the water is obtained through home made reverse osmosis system.

An important advancement in the purification of water through home made reverse osmosis sap systems came from the sugar industry, where large amounts of fuel were required to heat the sugar sap and evaporate the water it contained, in order to produce crystalline sugar.

Seawater generally contains 33-37 grams of dissolved solids per litre and to turn it into drinking water, nearly 99% of these salts must be removed.

In many countries, household drinking water filtration methods include a reverse osmosis technique for improving the quality of water for drinking and cooking.

There are now 13,080 home made reverse osmosis sap systems working around the world. Together they have the capacity to produce up to 55.6m cubic meters of drinkable water a day which makes up about 0.5% of global water use.

This is no doubt a remarkable achievement in the field of domestic water purification.
