AMALGAM-60 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). This contributes to the system’s stability and optimizes microorganism activity, as microorganisms don’t respond well to pH swings.
