Floating Cover-China - Case Study

" We have Thermophilic digested biological sludge, digested at 55 degrees. This is done in the digester, from which the sludge is fed to a open storage tank. Subsequently the sludge is dewatered, and the water from the dewatering is led to an "Anita Mox` process. This process should preferably stay above 18" degrees, so it is important that the temperature does not drop too low in the storage tank. To avoid this, we have installed Hexa-Coverand by doing this we have reduced the heat loss in the storage tank. The temperature of the Anita Mox` process is raisedfrom 17.2`Cto 19.7" C (measured from January to February 2013), despite temperatures down to-15° C. Henrik Thygesen, Coordinator - Operations.
