New Humitest for Measuring Sewage Sludge Water Content
Apr 29 2012
At the end of wastewater treatment, sewage sludge water content is about 99% of the raw matter. Reducing the mass to handle avoiding dust and improving quality are the primary issues of the valorisation and the recycling of sewage sludge. Treatment can occur by reducing its water content, notably through drying.
An on site moisture meter to improve working conditions and productivity. To be able to measure moisture content of sewage sludge (municipal sludge or industrial sludge) precisely, three parameters are significant: the representativeness of the sample, the reliability of the instrument used for measuring, the compliance of the operational mode by the person who measures.
The oven dry method is the reference test to measure sludge water content, but it is costly and time consuming.
Designed for instant and reliable measurements on site, the moisture meter for sewage sludge marketed by Domosystem (France) is calibrated according to the oven dry method.
Fitted with a measuring chamber, the new moisture meter allows to measure water content and temperature of sewage sludge granules/pellets. The user can also create his own calibrations.
