FIELD: microbiological water treatment processes.
SUBSTANCE: invention relates to microbiological water treatment process wherein alkaline water is subjected to neutralization with sulfuric acid. The latter is obtained directly in acidification stage performed by bringing initial water into contact with granulated sulfur in presence of bacterium species Thiobacillus. Furthermore, additional water treatment stage is possible, wherein initial water is clarified by filtration through grainy filter material.
EFFECT: increased chemical and environmental safety of process thanks to obtaining sulfuric acid directly in neutralization stage.
