The “osmosis” is the phenomenon for whichthereis a solvent flow (generally water) betweentwosolutionswith differentconcentrations of dissolvedsolutes, separated by a semipermeable membrane: the solventflows from the lessconcentratedsolution to the more concentratedone.
Industrial reverse osmosis systems are systemsthat force the passage of the solventmoleculesfrom the mostconcentratedsolution to the leastconcentratedsolution:thisisachieved by raising the water pressure of the system.
Reverse osmosisis a processthatallows to obtain pure demineralized water from water rich in salts.It’spossible to obtain a “desalination” of raw water both for domestic and industrial uses, thanks to special automaticsystemsthat use semi-permeablemembranes of differenttypes and materials.
The industrial reverse osmosissystemincludes a multimedia prefilter, a reverse osmosisunit with semi-permeablemembranes and UV sterilizeras post treatment. Thesemachinesapply reverse osmosistechnology by transportingfeed water through a multimedia pre-filter to removeparticleslargerthan 10 microns. Thesepretreatmentoptionshave the ability to removehardness, chlorine, odors, color, iron and sulfur.
The water to be treatedispushedinto the membrane (reverse osmosisunit) by a pump, whichexerts a pressure higherthan the osmoticone, so as to obtaintwooutflows: the part of the water entering the membrane constitutes the permeate (poor in salts) thatis water fresh and potable to be used, while the remaining part comes out with a high saltconcentration, due to the accumulation of all the saltsthathaven’tpassedthrough the membrane, itis the concentrate (rich in salts) that must be discarded.Finally, water ispassedthrough a UV sterilizer to killanybacteria and microbesstillpresent in the water.
The advantages of reverse osmosis are remarkable: applicabilityto waters with anysaltcontent andcontainedoperatingcosts, sinceit’s a processthatdoesn’trequireperiodicregenerationas for resinplants.
The Italian company B & P Water Technologies is one of the most important suppliers of reverse osmosis systems able to provide everything necessary to meet the requirements of water treatment, including RO plants, desalination plants and treatment plants of industrial waste water.
Their reverse osmosis desalination plants are completely assembled and tested before being sent to customers, so as to guarantee consumers that there will be no problems in using them.
All their water treatment products are designed using the most modern methods. To go without fail, just rely on B&P Water Technologies: a team able to provide the most energy efficient solutions to meet the needs of environmentally conscious customers.
