About

About Martin Marietta Magnesia Specialties Martin Marietta Magnesia Specialties is a global leader in the manufacture of high purity magnesium oxide and magnesium hydroxide products, which are used in a variety of environmental, industrial, chemical, and specialty applications. Additionally, Martin Marietta Magnesia Specialties is the largest producer of high purity dolomitic lime in North America. With its primary manufacturing facilities in Manistee, Michigan (magnesia plant) and Woodville, Ohio (dolomitic lime plant), Martin Marietta Magnesia Specialties also employs global and domestic distribution points to better serve its customers both domestically and worldwide. Martin Marietta Magnesia Specialties' high purity, magnesium hydroxide is used for pH control and alkalinity supplementation in wastewater treatment applications. FloMag® products are non-hazardous, environmentally friendly, safe and cost-effective treatment options versus caustic soda and lime. FloMag® H magnesium hydroxide buffers to a maximum pH of 9 in most wastewater streams, making biomass damaging pH excursions in biological wastewater treatment systems less likely. In addition, FloMag® greatly improves solids settling and dewatering, resulting in reduced sludge volume when compared to caustic soda and lime. FloMag® H magnesium hydroxide slurry offers price stability relative to historical caustic soda price volatility.
