Abstract
Invenţia se referă la procedeul de reducere a durităţii carbonice a apei, provocată de sărurile de calciu şi de magneziu şi poate fi utilizată pentru preîntâmpinarea formării pietrei de cazan.Esenţa invenţiei constă în aceea că procedeul prevede tratarea apei cu un curent periodic cu impulsuri dreptunghiulare directe şi indirecte cu frecvenţa de la 1,1...1,3 kHz până la 2,3...2,5 kHz şi invers cu perioada de 8...10 µs şi valoarea amplitudinii curentului de 2,5...3,0 mA, totodată tratarea apei se efectuează în prezenţa unei suspensii de particule feromagnetice coloidale ale oxizilor şi/sau hidroxizilor de fier în cantitate de 0,01...0,05 g/l, la viteza curentului de apă de 1...3 m/s.Particulele coloidale ale oxizilor şi/sau hidroxizilor de fier se obţin prin încălzirea soluţiei apoase slab alcaline a sărurilor de fier(II) şi fier(III), luate în raport de 1:2.
