Sludge Dewatering Equipment

Sludge Dewatering Equipment

Excess amount of water is still present in sludge thickened and it needs to be removed to have more stable and easy to-handle sludge in less volume and to make it less expensive for transporting.

We offer most common methods of sludge dewatering such as belt press and filter press.

Our Engineers are always ready to help you choose the most efficient sludge dewatering equipment.

Sludge dewatering systems can be custom engineered and integrated into your process to remove solid waste and extract water from sludge. Choosing the correct sludge dewatering system that is right for you and your process is vital for maximum efficiency and low operating costs. 



Belt presses are the equipment working continuously and used for dewatering of sludge from municipal and industrial wastewater treatment plants as well as water treatment plants in medium and large sizes. They are cost-effective, efficient solutions for dealing with sludge flows in large scales. Main working logic is based on filtering the water by pressing the sludge between belts and drums. One of the most important points maximum efficiency from belt presses is the selection of best-fit equipment. Sismat offers the best solution according to the customer demands. The capacity and performance of belt presses can be defined with regard to the criteria below:

  • Belt width
  • Pressure applied
  • number of drums
  • Pre-dewatering section height

Sismat Belt Presses are mainly made up of pre-dewatering part, cake thickness adjustment part (in MBP and HBP series only), low-pressure dewatering part, high pressure dewatering part, belt washing part and cake transportation part.


A filter press is a type of mechanical equipment which achieves solid-liquid separation of slurry using pressure filtration with the help of filter plates and clothes. Filter presses are the parts of batch operations and commonly used for sludge dewatering in municipal and industrial wastewater treatment plants due to their economical and easy-to-operate design. Filter presses are generally consist of metal components, plates and filter clothes. The main purpose of metal components is to protect the filtration unit from pressure applied during operation. Filtration unit is the part of equipment which separate solid and liquid in filter presses. This unit is composed of the plates having the same sizes.
