Gravity thickener IFTP

for sludge treatment

The sludge thickener with peripheral drive is installed on medium and large size treatment plants if a substantial reduction of the percentage of water contained in the organic or inorganic sludge is desired. This type of thickener consists of a mobile steel girder, a baffle cylinder, a scraping system with two blade holder arms in the lower part and a set of pickets in the higher part, double lateral trolley, two rotation units with peripheral drive, each complete with an electric motor and a gear box. The sludge inlet is in the middle, but the flow is deviated by the baffle in order to optimise the thickening. The sludge scraper blades, made in standard section, remove the sludge accumulated on the bottom and collect it in a central pit wherefrom, by a piping, is conveyed to the outlet. Blades and pickets are adjustable. The standard construction is in carbon steel. On request it is possible the construction in stainless steel or aluminium.
