Suitable for piggery wastewater treatment!

Ishikawa Stockbreeding, Inc.


Ishikawa Stockbreeding, Inc. had faced problems with labor and maintenance works accompanied with the handling of excess sludge, generated from their piggery wastewater treatment plant.
Before installing VOLUTE™ Dewatering Press, the excess sludge had been treated by all of the workers in the firm through a series of process; pumping the sludge, carrying out and disposing. These time-consuming and burdensome works had been regarded as major problems.

AMCON's offer for a solution

Ishikawa Stockbreeding, Inc. decided to install a sludge dewatering equipment as a solution to their problems. After having undergone a thorough examination of various sludge dewatering equipments in terms of their performance, cost and operational easiness, they decided to choose VOLUTE™ Dewatering Press. VOLUTE™ Dewatering Press with its clog-free-self-cleaning structure allows fully-automatic operation and these characteristics considerably minimized their burdensome works. As a result, they now have enough time for their main work, which is taking care of pigs rather than sludge handling.
In addition, they now make compost out of the sludge cake discharged from VOLUTE™ Dewatering Press by using a composting unit. The compost made is sold as a product and they now pay "zero cost" for sludge disposal.

We are proud to be given such a comment by the president of Ishikawa Stockbreeding, Inc., "Unfortunately, some people in the same profession think that a fine for sludge disposal is cheaper than the cost to buy equipment, which means that they do not understand the fundamental meaning of wastewater treatment. However the VOLUTE™ Dewatering Press has made our work easy."

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.”
