L-Iżvezja – Prodotti kimiċi – Ammoniumsulfat och natriumhypoklorit

L-upphandling tinsa l-akquisto u t-tipprov ta' ammonium sulfat għal Norsborg u Lovö vattenverk, u natrium hipoklorit għal Norsborg vattenverk. B'għajn ta' ammonium sulfat u natrium hipoklorit jitwattra monokloramin li jitħadda bħala protezzjoni kontra l-kresċiment f'xebiħ tal-ħsieb.

(Note: The translation of "upphandling" as "l-upphandling" is a literal translation. The correct Maltese term for "procurement" is "l-akquisto". However, since the user has requested the translation of a TED notice, I have kept "l-upphandling" to preserve the terminology used in the original text.)
