  • Reduction of sludge volume in waste waters at the end of the drinking water treatment process : [master thesis]
    Fakin, Rebeka, fizičarka
    Water treatment at Seierstad drinking water treatment plant is done by chemical coagulation using aluminum-based coagulant. The quality of the drinking water source - Lake Farris, has decreased ... throughout the years, that is why more and more particles, organic matter and dissolved minerals must be removed. That contributes to the volume of sludge being produced at the end of the process. The main objective of the assignment is to reduce sludge volume by coagulation and flocculation in the sedimentation basins using a coagulant/flocculent. In order to choose the right coagulant tests have been performed in the laboratory and on the actual process. The laboratory analyses showed great potential and one of the coagulants has been chosen and tested on the actual process. The testing was followed up for the entire summer of 2016 and then compared to the year before. We have been following the pH and Al3+ content in the water being released back to the environment and visibility in the top water layer in the sedimentation basin. Cost analysis, including the cost of chemicals and electricity usage, has been done. The sludge reduction was successful, and it was approximately 49 % less than the year before.
