  • The intermediate thermal hydrolysis process: results from pilot testing and techno-economic assessment

    Thermal hydrolysis has proven to be an efficient pre-treatment process for sludge before anaerobic digestion (AD), by thermally enhancing organic matter hydrolysis. Recent research has shown that a new configuration with the existing technology can further enhance the efficiency of the system. The intermediate thermal hydrolysis process (ITHP) has been explored and tested in the Sludge and ...

  • Effects of thermal hydrolysis temperature on physical characteristics of municipal sludge

    Effects of thermal hydrolysis temperature on the physical properties of municipal sludge was further studied by a series of experiments. There was a decrease in bound water content with an increase in hydrolysis temperature, while there was an increase in pH at temperatures below 120 °C, and a decrease at temperatures exceeding 120 °C. An analysis of settleability, centrifugation and vacuum ...

  • Numerical simulation of drainage scenarios for lowering groundwater rise due to construction of a new barrage on the Nile River

    The government of Egypt constructed a New Naga Hammadi Barrage (NNHB) 3.6 km downstream of the Old Naga Hammadi Barrage (ONHB). Upon construction, the water level raised by about 0.5 and 4 m upstream and within the river reach between ONHB and NNHB respectively. In this paper, a two–layer groundwater model was built using MicroFEM to study the groundwater rising problem. The model was used to ...

  • Waterschapsbedrijf Limburg (WBL) - case study

    Along with WBL Sustec has tested and lab researched  the continuous thermal hydrolysis of the surplusslib of the wastewater treatment plants Hoensbroek and Venlo. On this basis is determined the most optimal hydrolysis method. Then for nine months on pilot scale tests were carried out to the thermal hydrolysis and fermentation of the surplusslib. The tests confirmed that by thermal ...

  • Thermal hydrolysis of waste activated sludge at Hengelo Wastewater Treatment Plant, The Netherlands

    The thermal hydrolysis process (THP) is a sludge treatment technique which affects anaerobic biodegradability, viscosity and dewaterability of waste activated sludge (WAS). In 2011 a THP-pilot plant was operated, connected to laboratory-scale digesters, at the water board Regge en Dinkel and in cooperation with Cambi A.S. and MWH Global. Thermal hydrolysis of WAS resulted in a 62% greater ...
