REVERSE OSMOSIS DEVICES IN LABORATORY USE

Reverse osmosis is a natural process which consist on separation water molecules from other substances. The main part of the system is TFC membrane(thin-layer, polyamide), which is connected with preliminary treatment filters (polipropylene fibre and active coal). It allows to get water, which is devoid of pollutions like heavy metals, bacteria, viruses, ions. It's an absolute filter with the smallest known porosity.

It doesn't require regeneration. Final stage of treatment is ion-exchange column, which allows to get ultraclean water.

Reverse osmosis devices:

OSMOTIC WATER - IDEAL FOR LABORATORY DESTINATION
easy and tested way to water treatment
special designed group of membranes for the highest efectivity of desalination

CAUTION:
Effectivity was defined for typical water mains pressure - 2,5-3,0 atm and water temperature - 12 °C. Higher pressure and temperature of entrance water will cause proportional increase of efficiency!

DEMINERALIZATORS IN LABORATORY USE

Modern demineralizators work on the basis of ion exchange. In columns, there is a composition of highly productive ion-exchange beds made by Rom and Hass or Purolite. Cationite removes cations, anionite -anions. Columns are connected with preliminary treatment filters(polipropylene fibre and active coal). Exchangeable hydrogen and hydroxyl ions create water particle.

Demineralizators DI-1, DI-2 :

water with the highest parameters of conductivity
efficiency up to 600 dm3/h
no power supply during production of demineralizated water
20 dm3 composite bed in one column
easy control and reliable working
components with atests
reduce of costs in compare with distilation and redistilation
constant measurement of water conductivity
