Abstract

Inventia se refera la procedeul de reducere a duritatii carbonice a apei, provocata de sarurile de calciu si de magneziu si poate fi utilizata pentru preintampinarea formarii pietrei de cazan. Esenta inventiei consta in aceea ca procedeul prevede tratarea apei cu un curent periodic cu impulsuri dreptunghiulare directe si indirecte cu frecventa de la 1,1...1,3 kHz pana la 2,3...2,5 kHz si invers cu perioada de 8...10 ?s si valoarea amplitudinii curentului de 2,5...3,0 mA, totodata tratarea apei se efectueaza in prezenta unei suspensii de particule feromagnetice coloidale ale oxizilor si/sau hidroxizilor de fier in cantitate de 0,01...0,05 g/l, la viteza curentului de apa de 1...3 m/s. Particulele coloidale ale oxizilor si/sau hidroxizilor de fier se obtin prin incalzirea solutiei apoase slab alcaline a sarurilor de fier(II) si fier(III), luate in raport de 1:2.
