Effect of Micropollutants in Wastewater on Recovered Struvite
Abstract:Struvite precipitation experiments were conducted in digested sludge and digester supernatant samples. Selected organic micropollutants (OM) consisting of ubiquitous pharmaceuticals, personal care products, industrial auxiliary substances and synthetic fragrances were measured in original samples and after the precipitation both in solution and recovery product. Depending on the used medium OM concentrations in recovery product varied explicitly. In precipitates recovered from digester supernatants 4-nonylphenols, carbamazepine, benzophenone, AHTN and HHCB were detected, 4-nonylphenols dominating. In recovery products generated from digested sludge, synthetic fragrances, 4-nonylphenols and organic phosphoric acid esters were noticeable.
