uklanjanje minerala iz vode

 

Desalinizacija vode

Desalinizacija vode

Odsoljavanje vode ili desalinizacija je postupak smanjenja (uklanjanja) minerala iz vode.. 

Nudimo sustave za desalinizaciju morske i boćaste vode.

Jedan kubični kilometar morske vode sadržava oko 40 milijuna minerala ,ukupno otopljene krute tvari (TDS) - kationi: kalcij, magnezij, natrij i kalij, te anioni: karbonati, bikarbonati, kloridi, sulfati i nitrati - povečavaju električnu vodljivost vode i koroziju, te daju neprihvatljiv okus (prihvatljivost određene vode za piće odreduje se prema razini ukupno otopljenih krutih tvari u vodi)

Proces membranske desalinizacije vode - prilikom razdvajanja dvaju tekučina različitih koncentracija (npr. čistu vodu bez soli i solnu otopinu) kroz polupropusnu membranu koja propusta otapalo ( vodu), a ne propusta otopljene minerale, tada prolazi kroz tu membranu samo čista voda u otopinu soli.

Otopina soli se razrijedi, a volumen solne otopine poveća i njezina se razina digne iznad razine čiste vode, te zbog toga dolazi do razlike u pritiscima, što nazivamo osmotski pritisak.

CWG Grupa Vam nudi sustave za desalinizaciju:

  • MORSKE VODE ( od 35-45000 ppm NaCl)
  • BOĆATE VODE ( od 3500-15000 ppm NaCl)
