A nev scheme of ammonia recovery developed while pigment obraining by ammonia precipitation avoiding harmful waste which is substituted by neutral solid ferric hydroxide precipitate and ammonium sulphate solution which is treated by calcium oxide with recoveruy and return of ammonia to the process. A genuine new scheme has been developed allowing to recover NH3 from folter lye without substantial investment. Product Description popup.authors popup.nrat_date 2020-04-03 Close
