Advantages

MDQ/MDQ-C Dehydrators
• Energy saving + compact design MDQ/MDQ-C series energy savings are achieved by unique construction features. The 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 from a cabinet 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 make a self-cleaning mechanism. Therefore, it seldom clogs and equipment can run continuously.
• Capable of treating Oil-contained sludge
Equipment can dehydrate sludge with high oil & grease concentration. It is an optimal solution for treating oily DAF sludge at food processing factories where filter systems and centrifugal separation are not ideal. Thus, the equipment boasts a 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 an eco-friendly design that generates low noise and vibrations and emits no odors.
• Capable of treating low concentration sludge The Dehydrator includes both gravity thickening and dehydration compression zones. Therefore, the dehydrator can cope with a sludge concentration range from 0.3-0.5% to 10% of DS content.

MDQ/MDQ-C Dehydrators
• Continuous automatic operation
Since the equipment is constructed to avoid clogging, washing is not needed in order to restore the original filtration performance. Only washing with minor amounts of water is necessary to clear away sludge that might leak from the dehydration zone. Thus, the amount of wash water is minimal.
.• Unattended continuous automatic operation Operators can turn on the automatic operation mode of the Dehydrator and related equipment by simply pushing the button mounted on the control cabinet. This will place the dehydrator in automatic operation according to programmed operation algorithms.
• Wide product range Screw Press Dehydrators are available in a wide range of models with treating capacity ranging from 3 to 300 kg of DS/h with a maximum of 5 dewatering drums. Customers can select from 14 models of equipment according to the size and needs of the specific 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. There are two types of Screw Press Dehydrators that can be used depending on the type of initial sludge and installation conditions: - Model MDQ which is equipped with a technological chamber for initial sludge; - Model MDQ-C which is not equipped with a technological chamber for initial sludge.
