Office building with underground wastewater treatment plant
WWTP, Japan
- VOLUTE™ Sludge thickener
- WAS (SAS)
- WWTP, Japan
Problem
Some office buildings and large commercial facilities have wastewater treatment facilities underground. In such case, it is difficult to take dewatered cake conveyed 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.
AMCON’s solution
The VOLUTE™ thickener met their request. Thickening sludge reduced the frequency of removing sludge, thus achieving the cost reduction. Moreover, the VOLUTE™ thickener mechanically concentrates sludge, differently than other devices that utilize gravity for thickening, always discharging sludge at a constant concentration. Also, they appreciate VOLUTE™ for its advantages such as its small footprint, power savings, and minimized cleaning water consumption. The thickener installed in this facility thicken the sludge from 12,000 mg/L (before thickening) to 30,000 mg/L (after thickening), which satisfied the demand of the user very much.
