Squeeze sludge fresh out of the reactor. Don’t wait until it stinks!

Municipal sewage application (Nagano Prefecture)

Problem

In the wastewater treatment plant of a town in Nagano, the long-used belt press was in a time to be overhauled. The person in charge had racked his brain over the problem of huge cost required to overhaul this equipment at regular intervals. He had been seeking a solution to this problem.
In addition, he had to cope with another knotty problem that a planned new construction of sludge treatment plant cost had to be lowered as possible.
Furthermore, there had been multiple problems in this town in connection with sludge treatment including odor problem generated from the Sludge Thickening Storage Tank, the employment cost of resident staff to manage the existing dewatering equipment.

AMCON's offer for a solution

The encounter with VOLUTE™ Dewatering Press resolved all these problems in this town. The person in charge started with setting up VOLUTE™ Dewatering Press at a cost of overhauling the existing belt press, which allowed him to avoid the burden of regular huge overhaul cost. As concerns odor problem, one of the features of VOLUTE™ Dewatering Press (direct dewatering system from OD tank) substantially-improved the odor.
VOLUTE™ Dewatering Press also allowed him to reduce resident staff to manage the equipment and the employment cost.

The introduction of VOLUTE™ Dewatering Press was included in a new construction of sludge treatment plant in the basic design phase. With this introduction, there were no need of Sludge Thickening Tank and Sludge Storage Tank, which resulted in about 20 million yen reduction of construction cost.

Dewatering low-concentration sludge

Manufacturing Plant of Synthetic Fiber Materials in Indonesia

Problem

Before installation of VOLUTE™ Dewatering Press, they threw cake into their dryer after dewatering by their belt press . Drain of Synthetic Fibers purified from oil was not suitable for micro-organisms and was low MLSS. In addition , sludge concentration from thickening tank was quite low(6,000mg/L). So, Water content in Sludge cake became 92% by belt press machine. Because of throwing the soft sludge like Tofu, the load was pretty high.

AMCON’s offer for a solution

Since VOLUTE™ Dewatering Press adopted the unified structure that serves two functions, thickening and dewatering in the single machinery, the low concentration sludge can be dewatered. The drum filter, because of the clog-free, realizes higher speed of filtering phenomena per filtering area as compared to the methods, and the sludge is instantly thickened by gravity. They can constantly throw sludge into the dryer by installation of VOLUTE™ that can keep 85 % of water content so easily.

Dewatering of oily sludge without clogging

Chicken processing plant in Ukraine

Problem

The chicken processing plant in Ukraine had a big issue on tremendous amount of sludge disposal costs due to direct disposal of the sludge without dewatering. They had tried to look for a suitable sludge dewatering equipment for easy dewatering of the oily sludge, however it was almost impossible to find.

AMCON's offer for a solution

The customer installed ES-303 model understanding of the advantage of VOLUTE™ Dewatering Press; high resistance to oily sludge.
Customer’s comment: “We used to hesitate to install dewatering equipment due to anxiety for problems such as clogging and frequent maintenance of equipment for dewatering of oily sludge. However we are surprised at the fact that VOLUTE™ hardly has clogging. The full automatic operation is very helpful for easy management. The water content in sludge cake is as good as 71.5%, which is the performance of the VOLUTE™ Dewatering Press we are greatly satisfied with. We really realize that the installation of VOLUTE™ is the best choice we made.”
