FloMag® Magnesium Hydroxide:
The Safe And Effective Wastewater Treatment Alkali
A non-hazardous (by DOT standards), environmentally-friendly magnesium hydroxide slurry, Martin Marietta Magnesia Specialties' FloMag is a safe and cost-effective method for alkalinity addition and pH adjustment of acidic waste streams. FloMag’s minimal requirements for safe handling, storage and use make it the smart choice for wastewater treatment versus caustic soda or lime.
FloMag greatly reduces sludge compared to lime-treated sulfate systems and caustic treated heavy metal systems for reduced disposal costs. In addition, FloMag magnesium hydroxide buffers to a maximum pH of 9 in most wastewater streams – making biomass damaging pH excursions less likely. (Lime and caustic soda can easily reach a pH of 12 and 14 respectively).
Martin Marietta Magnesia Specialties' FloMag offers price stability relative to historical caustic soda price volatility.
