Disc Press JD


Highly efficient equipment for dewatering industrial and domestic wastewater sludge.

Disc Press JD is a highly efficient equipment for dewatering industrial and domestic wastewater sludge.

  • The JD Disc Press can be used as the main stage for the purification of wastewater from livestock complexes (hydraulic washes, scrapers, etc.).
  • They are ideal for small to medium-sized wastewater treatment plants.
  • Unlike traditional types of dewatering equipment, the Disc Press processes sludge with coarse and fibrous inclusions successfully and cost-effectively.

Scope of application of Disc Press JD:

  • Sludges of municipal wastewater treatment plants;
  • Food industry (dairy, meat, fish, beer, etc.);
  • Stockbreeding and biogas complexes;
  • Textile and leather industry;
  • Pulp-and-paper and woodworking industries.

Multi-Disk Dehydrator JD

Features and efficiency of JD Disc Press:

  • High degree of dewatering of sludge with a high content of fats, oils, petroleum products and sludge with abrasive particles.
  • Self-cleaning roller design eliminates clogging problems and the need to shut down equipment to clean the filter surface.
  • The special self-cleaning ability of the filter pores eliminates the use of water for rinsing them.
  • High efficiency due to minimal energy consumption.
  • Low weight compared to other dewatering systems.
  • Low operating costs.
  • Compact and closed design, which requires little installation space and low ventilation costs.

Reliability, easy of operation and maintenance of JD Disc Press:

  • Maintenance of equipment can be carried out by plant personnel without the need for special training.
  • The Disc Press control system has built-in protection against incorrect process settings and overflows.
  • The main components of equipment and electric drives are easily accessible for maintenance.
  • Due to the low rotational speed of the rollers, multi-disc dehydrators are characterized by minimal noise and vibration.
  • Thanks to the built-in sludge conditioning system, additional tanks and agitators are not required for the dehydration process.

Durability of JD Disc Press:

  • JD Disc Press casing is made of AISI 304 or AISI 316 stainless steel.
  • Additional mandatory anticorrosion treatment in the form of volume etching and passivation by special agents.
  • Working chains for transmission of rotation between the driving and driven rollers are made of high-strength metal.
  • Disc material is epoxy-based wear-resistant plastic and stainless steel.
  • The shafts on which the discs are mounted are made of special extra strong stainless steel.

How do I know which dehydrator to use – JD Disc Press or MDQ Multi-Disc Screw Dehydrator?

a) JD Disc Press is used when the dewatered sludge is highly mineralized (less than 60% of organic content in dry matter) b) When the sediment contains relatively large solid or fibrous inclusions (straw, fibers, particles of animal origin, etc.).

How often should the rollers be replaced?

Rollers discs are replaced as they wear out. Typically, critical wear of discs occurs after 5 to 7 years of operation. The replacement can be made without involving the manufacturer's representatives.
