Iron(II) sulfate monohydrate (FeSO4·H2O)
Coagulants for industrial wastewater treatment and sewage treatment, hydrogen sulfide and ammonia adsorbents, pigments, water purification agents, preservatives, disinfectants, and other feed additives for agricultural use.
Ferrous sulfate monohydrate is produced by centrifugally removing the crystallization water from the heptahydrate and then drying it. Compared to the heptahydrate, ferrous sulfate monohydrate is less prone to oxidation-reduction reactions in the air and has the characteristic of containing a large number of iron ions. ◎ Industrial Use It is used as a raw material for pigments and in wastewater treatment applications. In wastewater treatment, it functions as a reducing agent, coagulant, and precipitant. - As a reducing agent, it works to reduce hexavalent chromium to trivalent chromium in chromium-containing wastewater. - As a coagulant, it has a fast sedimentation rate, large and dense sludge particles, good removal effect for coloring agents, and the advantage of being inexpensive. - As a precipitant, it can form precipitates with sulfides and phosphates, allowing for the removal of these substances. ◎ Feed Use It is used as an animal feed additive, serving the role of iron supplementation. Iron is an essential nutrient for animal growth, being a crucial component of hemoglobin, myoglobin, cytochromes, and various oxidative enzymes. It also enhances the quality of livestock meat, giving it a more vibrant red color. ◎ Fertilizer Use It is used as a fertilizer to supply iron to plants.
