Project objectives: 
There is a large need to develop technologies to optimise thickening/dewatering management systems at sewage plants with the objective to optimise the treatment 
of sludge. The need from the market is a technique which can:    
- measure the electric charge of the particles in the flocks;    
- analyse the contents of the flocks, determine the optimal volume and compound of chemical additives;    
- detect the presence of hazardous pollution;    
- have a direct surveillance and communication with the monitoring of the treatment.
Project Summary: 
All over the world there is a need to purify and re-cycle waste water in order to improve the balance of water resources. In many parts of Europe, and also all over 
the world, there is lack of water of good quality at a reasonable price. An important part of waste water treatment plant is the sludge handling. In this project 
we focus on trying to improve the thickening and dewatering of sludge by a more sophisticated system to regulate these systems.    
In most kind of thickening/dewatering systems chemicals (polyelectrolytes) are added to form particles into flocks. The result is depending on amount 
and kinds of chemicals added. The sludge mixture is normally overdosed with chemicals to compensate for possible changes in the sludge mixture. Both over - 
and under dosing gives a faulty results. In most cases all adjustments, of the chemical additives dosage, are made by knowledge acquired from experience and 
without direct control or measuring. At certain intervals, or when the result is not satisfactory, samples are sent to laboratories for tests. The test results 
are used to adjust the mixture and quantity of chemicals.
