Farewell to Oily Sludge and Clogging Issues

Tecroveer, our distributors of VOLUTE™ Dewatering Press in South Africa had succeeded in winning a significant industrial project in a poultry farm in Rustenburg, a town located 130 km north-west from Johannesburg.

This poultry farm is the biggest chicken processing plant in the Southern hemisphere, with an average production of around 400,000 chickens a day. The company employs over 5,000 people working on a three-shift schedule. The production runs for 20 hours a day followed by 4 hours of maintenance.

VOLUTE™ Dewatering Press ES-352-SA-CE in South Africa

VOLUTE™ Dewatering Press ES-352 was placed in the wastewater treatment plant to dewater sludge from an advanced DAF technology called GEM (Gas Energy Mixing System). The product – nutritionally rich cake was transported to the cookers and added as a component to the by-produced animal feed.

When it comes to oily sludge, conventional dewatering technology faces major problems such as clogging, daily cleaning process, etc.

Our key to successfully unlock the process is the unique dewatering drum design. Layers of spacers and rings (fixed and moving) construct a cylinder.

The moving rings, which are slightly smaller than the outer diameter of the screw and slightly narrower than the spacers, are located between the fixed rings and are moved by the screw. Moving rings continuously clean sludge off the gaps and prevent clogging. This is the secret self-cleaning movement that enables handling oily and greasy sludge without any issues.

Overall, the end user was very satisfied with the VOLUTE™ technology and left a voice as follows:

“We had to replace the old DAF unit for a new one and include the dewatering step in the process. The new DAF unit is GEM, and for dewatering, we use AMCON’s VOLUTE™ Dewatering Press ES-352. The VOLUTE™ has reached exceptional results. We are now running the whole effluent plant ourselves, and everything is running smoothly. Thanks, guys, for sorting out those problems.”
