Abstract: Compania Aquaserv is the regional operator for water and sewage services in Mures and partly in Harghita country. The company recently completed a rehabilitation project in wastewater treatment plant Tîrgu Mures, regarding the sludge infrastructure. Additionally to the existing process formed of sludge concentration, anaerobic digestion (including biogas utilisation in CHP unit) and mechanical sludge dewatering were added two new elements: ultrasonic sludge disintegration and thermal sludge drying. Due to the new technology the efficiency of the digestion and the biogas production increased. The quality of the sludge resulted at the end of the process line is highly improved (humidity, odour, general aspect) and the quantity is lower.
