A study was conducted to investigate the effect of chemical substances on improvement of hygiene properties of sewage sludge. The chemicals used included H3PO4 and lime which belong among substances with disinfectant effect. These substances increase hygiene level of sludge and improve its properties important for application to soil by increasing its agronomic value in terms of important nutrients.
