How to Calculate of Reverse Osmosis desalination rate?

Reverse osmosis (RO) was invented in the late 1960s to desalt salty water sources. This method uses the osmosis principle and necessitates the use of a membrane barrier to separate salts from water. Because reverse osmosis required far less energy than distillation to operate, it was thought to be the technique that would make desalination much more accessible to the world's water-scarce places. Indeed, RO for water purification is now widely used not only for drinking water, but also for high purity industrial process applications such as electronic component manufacturing, pharmaceuticals, chemicals, boiler feedwater, medical applications, and industrial and municipal wastewater recovery systems.

Desalination by reverse osmosis

Desalination technology has brought clean water, as well as industrial and commercial growth, to parts of the planet that would otherwise be unproductive.

For the greater part of a century, desalination technology has been around. Due to a shortage of natural fresh water sources, many governments, towns, military forces, and ships must create fresh water by desalination. Desalination technology has brought clean water, as well as industrial and commercial growth, to parts of the planet that would otherwise be unproductive. Not only has this technology aided growth, but it has also aided many people's health and welfare by providing clean fresh water sources.

Salt Water Reverse Osmosis Principle

The usage of an osmotic membrane is required for RO desalination (i.e., one that allows water to pass through it at much higher rates than dissolved salts). Osmotic membranes are found naturally in all living species. Because of its capacity to allow certain elements to flow through while blocking others, the osmotic membrane is also known as a semi-permeable membrane.

The solvent water goes through the membrane in osmosis until the pressure differential across the membrane equals the osmotic. A pressure larger than the osmotic pressure applied to the saline water causes fresh water to flow through the membrane while the solutes are held back in the reverse osmosis desalination process (salts). The rate of fresh water transfer through the membranes increase when the applied pressure rises above the osmotic pressure.

Calculation of RO desalination rate

Permeability can be obtained by,

Permeability = The amount of water permeated per unit time,

=L/H÷ Unit membrane area, in m2

Desalination rate = (salt content of reverse osmosis treatment influent water in mg/L)-(Salt content of reverse osmosis treatment effluent in mg/l) ÷ salt content of reverse osmosis treatment influent water in mg/L

Water recovery rate

Water recovery rate = permeate effluent water volume,

=L÷ Influent water volume, L

Boiler Blowdown Rate

Boiler blowdown rate = (salt content in boiler feed water, sodium content or silicon content, in mg/l)-(Salt content in boiler steam) ÷ (salt content in blowdown water in mg/l/L-boiler feed water Salt content)

For softened water

Boiler blowdown rate = (Salt content in boiler feed water, sodium content or silicon content) ÷ (salt content in blowdown water-salt content in boiler feed water)
