GRAVITY TABLE | |
重力による水分除去用の非常に効果的な装置。 |
![]() |
Highly effective equipment for dewatering by gravity. Operation at a minimal cost, low volume of wash water consumed. Sludge is flocculated by the use of polymers, introduced on the belt and the released water is drained through the gravity belt. While the process is simple, the decrease in sludge volume is impressive. Some features are included to maximize performance and minimize maintenance (replaceable plow shoes and variable speed drive motor). Operation to process a wide range of sludge, flows and solid concentrations. |

BELT PRESS | |
2本の浸透式ベルト間で積極的な圧縮を加えることで広範囲のスラッジから水分を除去するためにデザインされたダブルベルトの水分除去装置。 |
![]() |
Double belt dewatering machine designed to dewater a wide range of sludge, by means of progressive compression between two permeable belts. 3 different draining zones: Gravity zone, consisting of the upper belt supported by high density polythene bars where most of the water is drained by gravity. Wedging zone (medium pressure section), where upper and lower belts approach each other and form a “S” configuration by means of pressure rolls with a decreasing diameter along the working direction of the machine so that pressure exerted on sludge gradually increases to produce a stabilized cake. NIP zone, consisting in 2 high pressure NIP that allows to reach higher performance of dryness in sludge final cake. The cake leaving the high pressure zone is removed from the belts by two doctor blades. The cleaning of the belts is performed by two washing stations, one for each belt, consisting of a pipe with high pressure jet nozzles. Two pneumatic systems provide the tensioning and the automatic centering of the belts. The Gravity Table installed on Belt Press is giving the Cascade, a solution allowing to dehydrate sludge that has not been previously thickened (dry solid concentration between 0,5-1,5%), with consequent advantages in terms of costs and installation space and also to assure high performance of separation and easy maintenance. |
