Water and sludge treatment products

Sludge Dryer
SP Series

This system can convert waste activated sludge and chemical sludge into dried sludge with a water content of 10 to 40%, reducing the amount of the waste sludge. High thermal efficiency is achieved with the direct contact of the the dewatered cake to the heat source. The unique double layered drum structure ensures a sufficient drying area while providing a compact design.

ADVANTAGES

Significant reduction of waste sludge volume

By drying the dewatered cake with a water content of about 80% to the water content of 10 to 40%, the dryer significantly reduces the amount of waste sludge. Your sludge disposal cost is greatly reduced.

Water content and weight of sludge

Sludge condition Water content Sludge cake weight
Raw sludge 99% 10000kg
Thickened sludge 96% 2500kg
Dewatered cake 83% 588kg
Dried sludge 40% 167kg
30% 143kg
20% 125kg
10% 111kg

Compact design and easy installation

When combined with the VOLUTE™ Dewatering Press, the dewatered cake discharged from the dewatering machine is fed directly into the dryer which produces the dried cake continuously. Large-scale operating systems such as storage hoppers, large drying tanks, and motors are not required.
In addition, the unique double layered drum structure ensures sufficient drying area.
Its compact design makes it suitable for small facilities, and the installation is also easy.

Sludge discharged in flake form for easy handling

Dry sludge is continuously discharged in a flake form.
Discharging the dried sludge in this form reduces the scattering of the sludge and eases handling.
In addition, dried sludge with low water content is less likely to decompose than dewatered cake, making it less likely to produce foul odors when temporarily stored.

PROCESS FLOW

  1. 01

    Discharge of Dewatered Cake

    The dewatered cake with a water content of about 83% discharged from the sludge dewatering press is continuously fed into the dryer.
  2. 02

    Inside of the Dryer

    Dewatered cake fed to the dryer is gradually dried in the drying drum.
  3. 03

    Dried Cake

    Dried cake with a water content of 10 to 40% is discharged.

RENTAL

Rental of Sludge Dewatering Presses

You may wonder, “Can the machine dewater the sludge as desired?” or “Is it difficult to operate the machine?”
In addition to eliminating concerns before purchase, you can also use our products as a replacement machine during the service period of an existing dewatering machine or during the construction period of a wastewater treatment facility.

Flow for Product Installation

流れ
Feel free to contact us. After collecting information about your treatment process, sludge volume, operating hours, and other conditions, we will select the most suitable model for your sludge and your concerns. During jar test, we will simulate the amount of chemicals to be dosed, the estimated water content of the dewatered cake, dried cake, etc. After determining the specifications and ancillary equipment, we will start producing the equipment. Our sales representative or service engineer will perform operational adjustments at your wastewater treatment plant and you will check how to operate the system before we hand over the equipment.
