W badaniach analizowano wpływ zasadowości koagulantu wstępnie zhydrolizowanego na skuteczność uzdatniania wody o niskiej zasadowości ogólnej. Wyniki przeprowadzonych testów wskazują, że zastosowanie koagulantu o małej zasadowości pozwoliło na uzyskanie wysokiej skuteczności obniżania absorbancji UV254(80%), porównywalnej do koagulantów wysokozasadowych, przy znacząco mniejszej dawce optymalnej Koagulantu...
Six prehydrolyzed commercial Al polychlorides of various basicity and aluminium sulphate (alum) were analyzed to determine the reliable method of Al speciation. The tests were carried out on the basis of colorimetric reaction of ferron with aluminum species. The analysis results were calculated based on two commonly used methods. The results have shown that the traditional ferron method may introduce...
