Sludge Dewatering Solutions

VOLUTE™ Dewatering Press
FS Series

Our standard model offers proven reliable dewatering and a user-friendly operation, with an exceptional build-quality. It offers all the usual VOLUTE™ benefits such as 24/7 automated operation, power-saving, water-saving, and low noise. Same as on all our units, it comes with advanced control modes which enable the most optimal and stable dewatering performance. The model size ranges from 100 to 200 000 PE.

Advance control modes to maximize performance

Several advance control modes for the sludge feed pump, polymer dosage equipment, and V-Screw speed constantly work together to optimize and stabilize the dewatering performance. This further reduces the required manpower for operation, decreases polymer consumption, and ensures that the machine is always processing the maximum amount of sludge. Having all parameters connected and controlled from a single point enhances user-friendliness and avoids complicated setup procedures.

Clog-free, even with oily sludge

The machine has a filter element (cylinder) that consists of alternating layers of Fixed Rings and Moving Rings, with spacers in between to maintain a gap that allows filtrate to escape. Inside the cylinder, a single screw conveys and subsequently pressurizes the sludge through the cylinder towards the end plate. As the screw rotates, it drives the moving rings up and down, which cleans the filtrate gap, creating a clog-free and self-cleaning mechanism. Only a very small amount of water at low pressure is periodically used to gently clean the rings from the outside. The design delivers stable dewatering performance even with oily sludge.

No pre-thickening required

The VOLUTE™ integrates both thickening and dewatering into a single machine. This allows direct dewatering of both high- and low-concentration sludges without any pre-thickening system. A feed concentrations as low as 0.5% TS is possible. This enables dewatering of aerobic sludge straight from the aeration tank. This eliminates the costs for construction and operation of thickening and storage systems and reduces odors. On top, it reduces phosporus and nitrogen emmissions back into the waste water treatment plant, by dewatering the sludge when it’s as fresh as possible.

  • Above throughput is calculated as approximate and may vary depending on sludge conditions. For model selection, please contact AMCON.
  • Throughput of each model is based on sludge cake with 20±5% solids content.
  • There is no definite upper limit on inlet sludge concentration; however, the target sludge must be flowable.
  • All the figures above are provided for the reference purpose only based on the standard design. The design may change without notice.
    Please contact AMCON for the latest information.

PROCESS FLOW

  1. 01

    Flocculation Tank

    Polymer and sludge are stirred and mixed, forming flocs suitable for VOLUTE™.
  2. 02

    Cylinder Unit

    In the first part of the cylinder unit - the thickening zone - the sludge is further thickened without much pressure being applied. In the second part of the cylinder unit - the dewatering zone - the pressure on the sludge is increased to squeeze out the water.
  3. 03

    Outlet for Dewatered Cake

    The end plate applies additional pressure to the sludge to get it to its final dry solids content.

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.

流れ
Feel free to contact us. After collecting information about your treatment process, sludge volume, operating hours, and other conditions, we will recommend the most suitable model for your sludge and your situation. After a free sample analysis, we will send you a report stating the expected amount of chemicals to be dosed, dry solids content of the dewatered cake, recommended technology, etc. Upon request, a pilot test can be performed at your wastewater treatment plant to further validate this data and let you experience the user-friendliness and reliability of our equipment. Based on your requests, we will then prepare a tailored solution proposal for a VOLUTE™ and auxiliary equipment. Before handover of the equipment, our service engineer will commission the unit on site and train the local operators to ensure the optimal result for you.
