    MDQ/MDC series

  • Dehydrators are designed for mechanical dewatering of industrial and municipal wastewater sludge

    Screw dehydrator MDQ EKOTON was awarded the Grand Prix at International Exhibition Fair of Machines and Devices for Water Lines and Sewage Systems WOD-KAN 2013 (Bydgoszcz, Poland)

    Excess sludge from biological processes.

    Coagulated sludge.

    DAF sludge from various industries.

    Different types of mixed sludge.

    Advantages

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

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

    Capable to treat Oil-contained sludge

    Equipment can dehydrate sludge with high oil 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 dehydrator and related equipment by simply flushing the button on included control cabinet. In this case dehydrator is put in automatic operation according to programmed operation algorithms.

    Wide product range Screw dehydrators are available in wide range, with treating capacity in range from 6 to 500 lb DS/h, with maximum 5 dewatering drums. Customers can selectfrom 13 models of equip-ment 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. There are two types of screw dehydrators that can be used depending on the type of initial sludge and installation conditions: - Model MDQ-XXX which is equipped with technological chamber for initial sludge; - Model MDQ-XXX C which is not equipped with technological chamber for initial sludge.

    1) Municipal wastewater treatment plant SBR (Szecseny, Hungary)

    One unit is installed at municipal WWTP and is designed for dewatering of SBR excess sludge and primary sludge mixture. Inlet sludge DS concentration is 1,5% and outlet cake DS concentration is 19-22%. Productivity by initial sludge is 10-15 m3/h (350-500 cu.ft./h)

    2) Olive oil and canned vegetable factories wastewater treatment plant (Ashdod, Israel)

    One unit is installed at industrial WWTP and is intended for dewatering of DAF sludge from WWTP which receive sewage from food manufacturing plants. Inlet sludge DS concentration is 5-6% and outlet cake DS concentration is 23,5%.

    3) Poultry factory wastewater treatment plant (Kanev, Ukraine)

    One unit is installed at poultry factory for dewatering of DAF sludge. Inlet sludge DS concentration is 10-15% and outlet cake DS concentration is 44%.

    4) Municipal wastewater treatment plant SBR (Melykut, Hungary)

    One unit is installed at municipal WWTP and is dedicated for dewatering of SBR excess sludge.

    5) Municipal wastewater treatment plant (Ozd, Hungary)

    Two units are installed at municipal WWTP and are dedicated for dewatering of thickened sludge. Inlet sludge DS concentration is 2% and outlet cake concentration is 20%. Productivity by initial sludge is 6-8 m3/h (210-280 cb.ft/h).
