In the Beijing Gaobeidian Wastewater Treatment Plant, sludge total solids from the primary clarifier varied from below 1 to 60 g/l, which means that from time to time only water is pumped to the sludge thickening tank. The Valmet TS total solids transmitter was installed in the outlet of the primary clarifier to control pumping.
Valmet will join the Global Cleantech Summit 2015 in September 8-10 to highlight the opportunities that Valmet’s technologies and solutions can provide to pulp, paper, energy and other process industries in creating more value from each processed tonne of feedstock or fuel.
The most important property of a shoe press belt, used in paper and board machines, is its toughness, in all probability. Tough material survives in even the hardest and fastest impact situations. In tests made at Tampere University of Technology, Valmet’s BlackBelt showed the best impact resistance compared to other belt designs.
