Lhoist Open House


Join us for a unique presentation on lime's water quality applications. Registration for this limited-capacity event is open to all.

This event will be a one-of-a-kind exposition on the capabilities of lime use in both municipal and industrial water & wastewater treatment. Participants will experience live slaking and slurry demonstrations, learn of best practices of lime storage, mixing, pumping, and dosing; and visualize jar testing comparisons to highlight differences between lime vs. caustic soda vs. magnesium hydroxide.

Safety equipment required: closed toe shoes, pants, no contacts.
