Cómo calcular la tasa de desalinización por ósmosis inversa

How to calculate reverse osmosis desalination rate

Permeability = the amount of water permeated per unit time, L/H÷unit membrane area, M2

Desalination rate = (salt content of reverse osmosis treatment influent water, MG/L-salt content of reverse osmosis treatment effluent, MG/L) ÷ ÷ salt content of reverse osmosis treatment influent water, MG/L

Water recovery rate=permeate effluent water volume, L÷influent water volume, L

• Low pressure boiler is less than 2.45MPA (less than 25KGF/CM2)
• Medium pressure boiler 3.82-5.78 (39-59)
• High pressure boiler 5.88-12.65 (60-129)

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

A simple qualitative method to determine the composition of circulating scale samples:

dissolve the precipitate, indicating that it is phosphate scale

Standards for judging scale and corrosion of water sample analysis:

PHS=(9.3+A+B)-(C+D)
