Low energy consumption and compact design
MDQ/MDC model's energy saving is achieved thanks to its construction features. The machine is designed to dehydrate sludge by gravity filtration and screw volume reduction. The equipment is compact and includes all necessary accessories operated by a control cabinet mounted on its base, allowing installation even in narrow spaces.
The filtration surface consists of two types of discs, which once assembled, form a self-cleaning mechanism. This allows the equipment to run continuously without clogging.
Oily Sludge Treatment
This unit can dehydrate sludge with high oil and grease concentrations. It is an optimal solution for treating oily DAF sludge at food processing factories, where filter systems and centrifugal separation are a challenge.
The dehydrator main unit dewatering drum, of semi-enclosed construction, runs at an extremely low speed. Consequently, sludge does not splatter from the equipment. The dehydrator generates low noise and vibrations.
Capable of Treating Low Concentration Sludge
The dehydrator includes both gravity thickening and dehydration compression zones, handling a sludge concentration range of dry solids from 0,3-0,5 to 10%.
Very Low Wash Water Consumption
Due to its clog-free filtering surface design, washing with water is not necessary to maintain the original filtration performance. Only a shower with a minimal amount of water is needed to remove sludge that may escape from the dewatering zone, therefore the amount of wash water is minimal.
Completely Automated and Unattended Continuous Operation
Operators can turn on automatic operation mode of the dehydrator and related equipment by simply pushing the button on its control panel. In this case, the dehydrator is activated according to programmed operation algorithms.
Wide Model Range
Screw dehydrators are available in a wide range of design and size, with capacity ranging from 6 to 500 lb DS/h, with a maximum of 5 dewatering drums. Customers can select from 14 models of equipment according to the size of the wastewater treatment plant.
For models with two or more dewatering drums, any individual drum can be serviced while others are in operation without interruption. There are two types of screw dehydrators that can be used depending on the type of sludge and installation conditions:
MDQ models equipped with a storage tank and sludge feed pump;
Model MDQ-C, without tank or sludge feed pump.
