Eliminating the need for tanker transportation and filter cloth cleaning. Daily sludge treatment has got easier

Plastic bottle recycling plant in Mexico

This recycling plant was using a filter press to dewater sludge, but the amount of sludge increased from the time of the installation. The sludge that exceeded processing capacity was therefore transported as liquid. Since the liquid sludge transportation alone costs the company fifty thousand dollars every month, they were looking for a new dewatering machine capable of handling the whole volume of sludge with a single unit.

VOLUTE DUO™ dewaters highly fibrous sludge

Ecological stretch film factory in Poland

This recycling plant, where plastic films for agricultural and industrial use are produced, dewaters a very fibrous sludge. This type of sludge contains up to 5 cm long plastic pieces which is making this sludge problematic to dewater. The pilot unit RVP-241 dewatered this highly fibrous sludge without any problems thanks to its patented double-cutting movement of the rings. The previous sludge dewatering equipment blocked after a few minutes of operation.

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.

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.

Removal of FOG (Fat, Oil and Grease) in raw wastewater

Frozen food factory in Japan

This frozen food factory was troubled with a high content of FOG (Fat, Oil and Grease) 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.

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.

Glass Recycling Factory in Japan

This factory recycles glass and processes them into small pieces which can be used for making glass bottles. Nevertheless, the pieces of glass need to be washed before having been shipped to another factory where the final product will be made and this cleaning water needs to be treated somehow. They had been using a belt press for dewatering sludge generated from their wastewater treatment plant, but because of its age, they started looking for a new sludge dewatering system.

Septic Tank in Ukraine

In the year of 2004 in Ukraine, there was no compact sludge dewatering equipment suitable for small-scale wastewater treatment facilities like septic tanks. As for septic tanks, it had been common that liquid sludge was disposed by tanker truck and delivered to central sludge dewatering facilities for post treatment. For that reason, the annual sludge disposal cost was extremely high, which had been a major issue among user and maintenance service company.

Large Commercial Facility (Office Building) in Japan

Some office buildings and large commercial facilities have wastewater treatment facilities underground. In such case, it is difficult to take dewatered cake out, so sludge is kept in liquid form and vacuumed out by pump without being dewatered. This potential customer also had been vacuuming out the liquid sludge, and had considered how to reduce the large cost of this industrial waste disposal.

Municipal sewage application (Nagano Prefecture, Japan)

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.
