The impact of marble powder on the performance small seasonal treatment plants dealing with high ammonia concentrated wastewater has been investigated. carbonate added to one two parallel lab-scale SBR-systems as an alkalinity depot and a bio-carrier. focus monitoring program was put measurement carbon fractions in liquid solid phase conditions. Monitoring results show significant correlation between dosage (and corresponding inorganic concentration pH-value) sludge volume index nitrification rate.
