This is the purification of a water sample, separating the suspended particles. The technique applied for reverse osmosis is a type of physical-chemical method to remove impurities from water, which passes through partially permeable layers, and is performed through water purifiers.ย  This disinfection of water removes electrical charges, atoms and other particles. It’s used in treatment structures to purify water in parts of the world for the creation of medicines, through chemical processes.

Such purifiers have pretreatment systems, feeding pumping equipment, pressurized tanks containing membranes, chemical dosing equipment, etc. to operate properly. The reverse osmosis technique has advanced widely in recent decades and has gone from being an emerging technology, to a consolidated, effective and professional process.

Technology using Reverse Osmosis

Reverse osmosis is a layered technology that separates the salinity of water by means of transmission processes through a semipermeable membrane that supplies the entry of dissolved gases and other elements without charge, of low atomic weight.ย  It is the convenient method for the elaboration of pure water with a low salt content, free of viruses and chemical contaminants. Osmosis membranes are used, whose configuration changes depending on the nature of the water to be treated.

Accordingly, some of the common applications of reverse osmosis are:

  • Manufacture of pure water in the main industrial sectors, such as: chemical, food, energy, electronics, among others.
  • Eliminating the conductivity of saline discharges
  • For desalination of seawater
  • It facilitates the readjustment of water consumption thanks to its regeneration and reuse.

The technology of these water purification systems, more than ever, are for treating wastewater, gallon by gallon, and these applications use less energy than seawater applications, for example. However, reverse osmosis was deployed to remove inorganic salts such as sodium chloride, organic materials, metals in untreated water and industrial waste.

Operation of Water Purifiers and Reverse Osmosis

Osmosis is a phenomenon in which the molecules are agitated crossing through a porous semipermeable membrane, from a region of lower concentration to another of higher concentration, to equalize the concentrations of both sides, creating an osmotic pressure to achieve an opposite effect.

Factors that affect the membrane filtration process include:

  • The quality of the inlet water
  • The operating parameters of the plant (pressure and degree of conversion).
  • Polarization of concentration.

All of this results in membrane fouling, derivative to the embedding of salts in it, and even its degradation.

In order to ensure the proper functioning of the osmosis, the use of water purifiers is essential for the execution of an adequate pretreatment, as well as the preventive and corrective maintenance of the operation.

In this way, laboratory water purifiers offer some advantages, including:

  • They’re environmentally conscious systems
  • They don’t consume much energy
  • They occupy a smaller space than other water treatment systems
  • They’re fully automated
