Claims (9)

1. Menetelmä mikrobisen kasvun estämiseksi prosessivedessä, tunnettu siitä, että alumiini-ioneja lisätään prosessiveteen ennen perhapon tai perhappo-jen seoksen lisäämistä tai perhapon tai perhappojen seoksen lisäämisen yhteydessä alumiini-ionien pitoisuuden saattamiseksi tai pitämiseksi 0,05 ppm:n - 100 ppm:n tasolla prosessivedessä, siten parantaen mainitun perhapon tai perhappojen seoksen biosidistä tehoa prosessivedessä, jossa perhappo on peretikkahappo tai permuurahaishappo tai niiden seos.
2. Patenttivaatimuksen 1 mukainen menetelmä, jossa perhappo on perkar-bonaatti.
3. Patenttivaatimuksen 1 tai 2 mukainen menetelmä, jossa alumiini-ionit ovat alumiinisuoloista, kuten alumiinikloridi, polyalumiinikloridi, alumiinisulfaatti, alumiinikloorihydraatti, alumiinihydroksidi.

5. Jonkin patenttivaatimuksen 1-4 mukainen menetelmä, jossa alumiini-ionit asetetaan prosessivedessä 0,5-20 ppm:n tasolle, edullisesti 0,5-5 ppm:n tasolle ennen perhapon lisäystä tai perhapon lisäyksen yhteydessä.
6. Jonkin patenttivaatimuksen 1-5 mukainen menetelmä, jossa prosessivesi sisältää puhtaan veden, jäähdytysveden, teollisuusprosessin kierrätys- ja jätevedet, suolanpoistoprosessien vedet.
7. Jonkin patenttivaatimuksen 1-6 mukainen menetelmä, jossa prosessivesi sisältää sellu- ja paperiteollisuuden, metalliteollisuuden, tekstiiliteollisuuden tai ruokateollisuuden teollisuusprosessivedet.
8. Jonkin patenttivaatimuksen 1-7 mukainen menetelmä, jossa prosessivesi sisältää vettä suolanpoistoprosesseista.
9. Alumiini-ionien käyttö 0,05 ppm:n - 100 ppm:n pitoisuutena prosessivedessä perhappoyhdisteiden tehon parantamiseksi mikrobisen kasvun estämiseksi prosessivedessä, jossa perhappo on peretikkahappo tai permuura-haishappo tai niiden seos.
