Sizes of iron hydroxide particles formed during ferric coagulation processes

Abstrakt

The aim of the study was to apply laser granulometer for measuring sizes of particles formed in iron-based coagulation process in water, which did not contain significant amounts of organic compounds. The research was conducted using tap water, obtained from underground sources. Iron sulfate in doses of 2.0–10.0 mgFe L–1 was added to water. During initial stage of flocculation, iron hydroxide particles reached dimensions between 0.03 and 0.5 μm (at coagulant dose of 2.0 mg Fe L–1) and between 0.1 and 0.5 μm (for higher doses). Maximum dimensions of flocks amounted to 130–500 μm and at doses greater/equal to 4.0 mgFe L–1did not depend on coagulant doses. Merely, for a dose of 2.0 mgFe L–1and after 40 min of flocculation, the flocks reached dimensions of 85–320 μm and continued to enlarge. With increasing dose of coagulant, flocks faster enlarged their dimensions and faster reached maximum sizes. Initially, the smallest particles with dimensions smaller than 0.1 μm still remained in the solution. Persistence of the smallest particles ranged up to 7 min.
