Hunter Water’s Largest Treatment Plant Installs Logmax® Clarifiers with Cleansweep®
The Burwood Beach WWTP is the largest sewage treatment system that Hunter Water operate, with a processing capacity of 44 million litres per day, or up to a population equivalent of 190000.
Overview
A recent upgrade included the installation of a new secondary clarifier system. EPCO Australia were awarded the design, fabrication, installation and commissioning of a 33M diameter peripheral drive clarifier mechanism.
The clarifier mechanisms consist of the following:
- A stainless steel rotating access bridge, suitable to carry one radius of scrapers complete with aluminium grating and handrail
- A peripheral drive unit consists of a shaft mounted gear motor, adjustable axial torque element and track wiper
- The scum skimmer is a hinged stainless steel blade with neoprene squeegee
- An array of LogMax® sludge scraper blades, suspended from the bridge by chains and vertical supports directs the settled sludge towards the centre pocket.
- To limit the growth of algae in the launder channel, a self adjusting launder broom assembly is utilised.
