Following the trend set by numerous other water authorities around Australia, two of HUBER’s largest rotary screw presses were recently commissioned for TasWater at the Ti Tree Bend Wastewater Treatment Plant in Launceston.
Hydroflux supplied these units to Aquatec Maxcon, who was the head contactor on the recent upgrade of the TasWater Biosolids Facility at the Ti Tree Bend plant.
The units supplied can each process up to half a tonne of dry solids per hour, which is generated from the anaerobic digestion process. Each machine is fitted with a 3kW main drive with an operating speed of up to 0.8rpm — an equivalent sized centrifuge would consume in excess of 40kW per hour with speeds over 3500rpm.
Anaerobically digested sludge is dewatered anywhere between 20-22 per cent dry solids which represents a volume reduction of 85-88 per cent.
Hydroflux has applied the HUBER QPRESS on a variety of municipal and industrial applications in Australia. Clients welcome the low energy usage, low noise, slow rotational speed, automatic unattended operation and low maintenance requirements.
The rapid uptake of HUBER QPRESS has led HUBER to build a separate production line dedicated to these machines which has reduced manufacturing costs and lead times.
These HUBER QPRESS units complement the existing HUBER SDRUM units which have been in operation since 2005. The SDRUM are thickeners which serve two purposes — waste activated sludge thickening and recuperative thickening.
