At Blue Grass Chemical Specialties, we manufacture high-quality ferric hydroxide in New Albany, Indiana, supplied as a slurry in drums or totes. Ferric hydroxide is a proven solution in water and wastewater treatment, effectively removing heavy metals and phosphates to reduce nutrient pollution. In anaerobic digesters, it enhances biogas quality by scavenging hydrogen sulfide (Hâ‚‚S), protecting equipment, reducing odors, and improving community acceptance. It also supports process stability by buffering pH and mitigating sulfide inhibition, often increasing methane output by 10–20%. Our product offers dependable performance that meets environmental standards and supports cleaner, more efficient treatment operations. This product is manufactured in New Albany, Indiana, and can be supplied in drums or totes.
