Sweden's largest sewage treatment plant, Henrikdal, will be rebuilt to receive twice as much sludge than they can do today. To have the ability to do that, either the level of total solids (TS) must increase or expand the rotary chambers. Off which the second option is to be avoided due to the high costs.The report will answer why the origin, viscosity, shear rate, temperature and TS-level of the sludge is important to consider when pumping it. Also, the report will show results of how the viscosity will get higher either when the TS-level or the shear rate is increasing as well as the temperature is decreasing. Beyond that, the report will contain source gathering, method, conclusion, discussion and ends with proposals for further research. |
