Wastes generated from industrial processes can be unpredictable, inconsistent and highly variable. Acidic industrial wastes are commonly neutralized with alkalis. The addition of alkalis alters the concentrations of dissolved and suspended solids, facilitating their separation by sedimentation. Sedimentation is the separation of solid particles from water by gravitational settling. In industrial wastewater treatment, the volume […]
Not all alkalinity agents provide equal treatment. A very important metric in alkalinity technology selection is the amount of alkalinity contributed with each gallon injected into treatment systems. Greater alkalinity contribution offers lower amount of chemical agent required, lower chemical costs, and lower transportation costs. FloMag®H Magnesium Hydroxide Slurry is such a high-contribution treatment agent. […]
Scaling occurs when chemistry conditions cause dissolved mineral salts to precipitate and form solid deposits. Scale is a problem because it narrows pipe widths and therefore compromises treatment system performance and increases the energy used in transporting aqueous flows through pipes, pumps and other conveyance elements. Wastewater commonly consists of dissolved matter of calcium content […]
Magnesium hydroxide is trusted by many of North America’s major corporations for wastewater neutralization, pH adjustment, and alkalinity supplementation by delivering a compelling envelope of technical, economic, and safety benefits. To deliver the highest quality engineering and technical support, Martin Marietta Magnesia Specialties established the Engineering & Applications Center more than 40 years ago to […]
“Reduce – Reuse – Recycle” has become a common way of thinking. Water industry thinking has taken big steps toward making this slogan a reality in everyday treatment operations. Waste treatment facilities have become resource recovery stations, enabling reuse of water resources. These recovery stations not only prevent organics and excess nutrients from entering our […]
Magnesia technologies are trusted by many of North America’s major corporations for wastewater neutralization, pH adjustment, and alkalinity supplementation by delivering a compelling envelope of technical, economic, and safety benefits. An important source of cost savings available to 50% caustic soda users originates from the greater alkalinity contribution of magnesium hydroxide. One gallon of magnesium […]
Magnesia contributes to many industrial applications. Two dozen industrial applications for magnesia are listed at this link.
Flame retardants are chemical additives used in plastics, coatings, and other products to inhibit flame sustenance. Magnesium hydroxide is used with a resin or similar base material as a flame retardant filler. This magnesia compound is physically mixed with the base material ( and “additive flame retardant”).
Magnesium hydroxide can offer economic and process benefits in pulp bleaching. Cost savings from the reduction or elimination of certain bleach chemicals can be achieved by employing CellGuard®MH magnesium hydroxide powder as an alternative alkali and cellulose protector. Additional benefits such as a reduction in BOD/COD and anionic trash can improve wastewater treatment and papermaking […]
