Abstract:As a substitute for extracellular polymeric substance
from waste
activated sludge, alginic acid (AA) has been proven to exert a significant
inhibitory effect on struvite crystallization for phosphorus recovery
from the sludge. The inhibitory effect is highly dependent on ionic
strength in the sludge supernatant, especially in terms of seawater
and brine as the magnesium source. However, the role of ionic strength
in the inhibitory effect has remained elusive. The purpose of the
study was, therefore, to compreh… Show more
