The sludge (solid concentration 1-5% DS) is concentrated, to obtain a solid content in the range from 18 to 40% DS. As a result of dewatering, the product achieves a solid consistency that allows to handle and dispose it easily.
Giotto Water offers a wide range of dewatering machines, designed to meet the specific needs for both civil and industrial applications.
Belt press filter, with an innovative design, to obtain the highest performances ever reached by a belt press filter. This result is achieved by increasing the working filtration area and the efficiency of the low pressure system (with wedging roll).
The mechanical components have been designed to guarantee reliability and continuity of operation, even in the more difficult operating conditions.
Belt press filter designed for dewatering both municipal and industrial sludges. The new modular frame concept combines outstanding performance with low capital costs, thus maximizing the costs/benefits ratio. It is suitable to treat sludges in a wide range of concentrations: the “Standard” version of the machine is designed to dewater sludges with standard solid concentration, while the “Cascade” version, in combination with a belt thickener, fits for very diluted sludges. The high pressure zone, modular, is available with 8 rollers: in option, it can be easily converted to an 11 rollers zone, adding a 3 rollers module to increase final dryness.
Belt press filter for dewatering of biological sludges, municipal and industrial.
Compact enclosed design, including a high pressure zone with 6/8 rolls. Simple and cost-effective construction, with minimum space requirement and efficient operational results. Frame available in hot dip galvanized or stainless steel.
Belt press filter designed for dewatering both primary and mixed fibrous sludges (pulp and paper industry, sugar beets mills, etc). It features a high pressure zone, with 7 “S” rolls of equal diameter, followed by a linear pressure NIP to further increase the final dryness up to more than 40% BDS with most fibrous sludge.
Belt press filter for mineral slurries, specifically designed to treat high flowrates at low feed concentrations. The large gravity zone and the long retention time in the low pressure zone, consisting of a large diameter perforated roll, enables the machine to effectively dewater sludges with very fine and unstable solids.
