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.

Major meat-process plant in Canada

In the meat-process plant in Canada managed by a world's leading meat-process plant, huge amount of sludge disposal cost had been a longstanding problem. In production process, approximately 96m3 sludge had been generated a day, and the sludge had been disposed by a waste disposal firm. This sludge disposal cost had reached as much as 93.6 million yen a year. The existing belt press had produced no substantive results in dewatering performance of the oil sludge generated in this plant. Oil sludge dewatering problem had been abandoned as hopeless to solve.

Secure treatment for high oil content sludge

Coffee manufacturing plant in Thailand

An instant coffee manufacturer in Thailand had dewatered sludge with a filter press. 10 to 20 percent of the coffee beans is oil, which has caused clogging of the filter and trouble to stop the equipment for maintenance.

Removal of the normal-hexane extracts in raw wastewater

Frozen food factory in Japan

This frozen food factory was troubled with a high content of normal-hexane extraction material (mainly oil and fat content) concentration in the waste water discharged into the sewage. However, other high hurdles such as the need of large-scale expansion for dewatering facilities or site prevented them from reaching the best solution. In such situation, AMCON received their consultation if VOLUTE™ can remove oil and fat content.

Installation in a narrow space

Meat processing factory in Japan

This factory had used multi disc type dewatering equipment for long time; however, they had been facing problems such as aging and lack of throughput of the equipment. Due to a limited space for the dewatering equipment, they were looking for compact dewatering equipment with larger capacity.

Dramatic Change in Efficiency Brought by The Installation of The VOLUTE™ Dewatering Press

Yamauchi Company (Japan)

Since sludge dewatering equipment had not been installed in their wastewater treatment plant, sludge had been treated with a sand filter and took them 1 to 2 weeks to dry. Furthermore, the dried sludge had been picked up and placed in a tub by 30 employees, and it took them an hour to complete their task. It was not only time-consuming but also required high labor cost. However, this was not the only issues that they had been confronted with in sludge treatment. Since the sand filter is installed outside, sludge treatment can be significantly influenced by the weather. For instance, there is a huge disparity in temperature between summer and winter, and this undesirable environment had affected their productivity to a great extent. Moreover, the fact that the time when the sludge dries depends on the weather made them difficult to treat sludge according to plan.

Our biggest models can dewater huge amount of sludge during summer months.

Juice Producer in France

After a successful pilot test has been carried out, AMCON successfully installed one of our biggest models, ES-351 in the Juice factory in France. Although they had been using a belt press until then, they were not satisfied with its performance and they were always looking for an alternative solution for their sludge dewatering until they found VOLUTE™ Dewatering Press.

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

Otokomae Tofu Inc. (Japan)

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.

VOLUTE™ Dewatering Press reduces maintenance time sharply!

Komagata Foods Co., Ltd. (Japan)

Komagata Foods Co., Ltd., manufacturing feed for fish cultivation, used to use a belt filter press, but they had always faced clogging problems because of the oily sludge. They also suffered from spillage over from the side of filter cloth, making operators to keep their eyes on the machine all day.
