The VOLUTE™ Dewatering Press Purchased Repeatedly, Plays a Very Important Role at a Tofu Factory.

Otokomae Tofu Inc.


Otokomae Tofu Inc. develops, manufactures and sells Tofu (Soybean Curd), with impressive product names. They installed the second VOLUTE™ Dewatering Press in their Kiyosato factory, following the first one installed in their Kyoto factory. We interviewed the responsible person to take care of the whole wastewater treatment plan to ask the reason why they have become our repeater.

AMCON’s offer for a solution

The responsible person had an experience to use a belt filter press. When the company was considering installing a sludge dewatering equipment in Kiyosato factory, he recommended that they install the Volute as well as Kyoto factory. "The reason why we installed the VOLUTE™ Dewatering Press again is its easy maintenance. In case of a belt press, we had to clean it up every day, every after we stopped operation. If we left dry sludge in the equipment, cake solids content would be lower. To make it worse, we had to operate the equipment 20 hours per day, with lower cake solids content. On the other hand, the VOLUTE™ Dewatering Press takes only 15 minutes per week in summer and 30 minutes even in winter to maintain it. The operation is stable and operation time is only 8 hours per day. Simple and effective."

When we were listening to his detail explanations going around in their wastewater treatment plant, it turned to the time to discharge supernatant. The crystal water is touching. Without any strong odor, he said smiling, "We could achieve this depending on our management." It is our most pleasure that the VOLUTE™ Dewatering Press could serve our clients.

Dewatering low-concentration sludge

Manufacturing Plant of Synthetic Fiber Materials in Indonesia


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


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.”
