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 […]
“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 […]
Acidic wastewater effluents are common across a wide spectrum of industrial categories. In a perfect world, industrial users of alkalinity agents would enjoy unequalled economic and technical benefits. Magnesium hydroxide slurry is a member of the family of industrial alkalis. Environmental professionals do not need to be held captive by higher-cost treatment agents such as caustic […]
Anaerobic digestion is used for solids reduction and as a method of energy production in wastewater treatment. Organics digesting bacteria use oxygen that is chemically bound in organic compounds such as starches, proteins, and fats.
Industrial processes that produce high ammonia loading in wastewater are common. Biological nutrient removal (BNR) systems employ sequential nitrification/denitrification to convert ammonium into harmless N2 gas. In nitrification, aerobic nitrifying bacteria convert ammonia to nitrate: Ammonia → Nitrite → Nitrate
