For decades, caustic soda has been known for price and supply volatility. As a result, it is not uncommon for current purchasers of caustic soda solution to investigate “caustic soda replacement”, “caustic soda substitution”, “caustic soda supplementation”, “caustic soda partial substitution”, or to be interested in “caustic soda comparison” with other “alternative sources of alkalinity” […]
Magnesium hydroxide is ”slightly soluble in water at room temperature”. “If magnesium hydroxide is only slightly soluble in water, how would it function in my treatment process?” Let’s provide an answer to that question! Martin Marietta Magnesia Specialties produces a high-solids, high-stability magnesium hydroxide slurry. Liquid slurry is magnesium hydroxide particles suspended in water. Magnesium […]
As emission limits tighten, fossil fuel electrical power generation plants are employing wet electrostatic precipitators (WESP) to control pollutants. WESPs generally use this post-combustion emissions control sequence: SCR → DESP → WFGD → WESP
CellGuard®OP Magnesium Hydroxide Slurry can offer several economic and process benefits in mechanical and chemical pulp bleaching. Cost savings from the reduction or elimination of certain bleach chemicals can be achieved by employing CellGuard®OP as an alternative alkali and cellulose protector. Additional benefits such as a reduction in BOD/COD and anionic trash can improve wastewater […]
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
