Adding magnesium to the waste can help make and extract struvite, which is a phosphorous-rich material. By capturing phosphorous in a biologically-available form within wastewater sludge, it can be composted and recycled as fertiliser, preserving nutrients in the land to ensure farming remains efficient for many more generations.

And if amounts of reagent are precisely adjusted, the water’s alkalinity will be reduced to the theoretical solubility applicable to the CaCO 3 + Mg (OH) 2 system which ranges from 2 to 3°F under normal temperature and concentration conditions.. However, this limit M-alk. figure may be increased in practice when dissolved impurities are present (e.g. organic acids, ammonium, phosphates, etc.).
