Advantages• Energy saving + compact design

MDQ/MDC series energy saving is achieved by construction features. Machine is designed to dehydrate sludge by gravity filtration and screw volume reduction with pressure. The equipment construction is compact and includes all necessary accessories controlled by control panel mounted on the same base. Therefore, it can be installed in a very limited space.

• Self-cleaning mechanism The filtration surface(drum) consists of two types of discs, which assembled together makes a self-cleaning mechanism. Therefore, it clogs seldom and equipment can run continuously.

• Capable to treat Oil-contained sludge

Equipment can dehydrate sludge with high oil&grease concentration. It is optimal solution for treating oily DAF sludge at food processing factories, where filter systems and centrifugal separation is hardly possible. Thus, the equipment boasts with higher solid capture rate.

• Minimal secondary pollution and maintenance The Dehydrator main unit – dewatering drum, is of semi-enclosed construction and runs at an extremely low speed. Therefore, sludge does not splatter from the equipment. The Dehydrator is of eco-friendly design that generates low noise and vibrations, and emits no odors.

• Capable to treat low concentration sludge The Dehydrator includes both gravity thickening and dehydration compression zones. Therefore, can cope with sludge concentration range from 0.3-0.5 to 10% of DS content.

• Continuous automatic operation

Due to equipment is constructed to avoid clogging, washing is not needed in order to restore original filtration performance. Only showering with minor amount of water is necessary in order to wash away sludge that leaks from the dehydration zone. Thus, the amount of wash water is minimal.

• Unattended continuous automatic operation Operators can turn on automatic operation mode of the Dehydrator and related equipment by simply pushing the button on included control panel. In this case dehydrator is putted in automatic operation according to programed operation algorithms.

• Wide product range Screw Press Dehydrators are available in wide range, with treating capacity in range from 3 to 300 kg of DS/hour, with maximum 5 dewatering drums. Customers can select from 14 models of equipment according to the size of targeted wastewater treatment plant.

• Multi-shaft construction When two or more dewatering drums are present in one machine, any individual drum can be serviced while others are in operation without interruption.
