Aerofloat delivered an effective wastewater treatment plant to ensure cost effective operations for the Brisbane packaging plant.
The wastewater at the Brisbane plant needed to be treated to a level suitable for sewer discharge and accommodate growth at the site.
Some structures within the system had also reached the end of their lifespan and required upgrades to ensure safe and effective operations.
Aerofloat installed its circular dissolved air flotation unit, the AeroCircDAF.
Aerofloat incorporated its AeroCirc DAF technology and associated process equipment, tanks and controls to treat the process wastewater to the sewer discharge standards and provided a new filter press system.
In addition to the compliant effluent result, Aerofloat’s design was compact and had a minimal environmental footprint.
Its sealed and vented tanks created an odourless plant, and the mechanical simplicity of the design, with its self-cleaning hopper bottom, ensured a maintenance-friendly system.
A prominent packaging and boxing plant required new wastewater treatment system to ensure optimal compliancy and accomodate growth.
Aerofloat was contracted to build a wastewater treatment facility to process the wastewater from the cardboard packaging plant after constructing similar plants at the client’s New Zealand and Melbourne facilities. It was able to draw on this experience to ensure the new Queensland facility exceeded expectations.
The prominent packaging and boxing company needed to upgrade its wastewater treatment plant in Brisbane to meet production growth. Aerofloat was contracted to build a wastewater treatment facility to process the wastewater from the cardboard packaging plant after constructing similar plants at Visy’s New Zealand and Melbourne facilities. It was able to draw on this experience to ensure the new Queensland facility exceeded expectations.
At the pre-existing plant, process wastewater was being treated by chemical flocculation and sedimentation prior to discharge to sewer. Waste sludge was being dewatered in a plate press prior to disposal to landfill. Aerofloat was contracted to design a low maintenance wastewater treatment plant that would ensure compliant effluent.
Aerofloat incorporated its AeroCirc DAF technology and associated process equipment, tanks and controls to treat the process wastewater to the sewer discharge standards and provided a filter press dewatering system.
From production, wastewater high in ink waste pumped over a 2mm rotary drum screen to automatically remove solids, labels and foreign matter. The screened wastewater then gravitated to a 46,000 litre balance tank to be pH corrected.
From the balance tank, wastewater was pumped through Aerofloat’s patented AeroCirc DAF with the capacity to treat flows of up to 12m3 per hour.
Aerofloat’s coagulant and flocculant were added to the wastewater process to create solid separation and the thickened floated solids were automatically scraped off the top of the AeroCirc DAF sludge hopper and pumped to a new 10,000 litre stainless steel sludge tank. The sludge was then mixed with an agitator to keep effluent mixed and homogeneous. The sludge was then pumped into the filter press dewatering system to produce filter cakes that could be simply disposed of. The filter press was able to achieve up to 40% solids content which significantly reduced disposal costs for Visy.
The system was logic-controlled to ensure only compliant effluent was discharged. Both the operators and Aerofloat’s engineers can access the system remotely via the eWon remote access system to allow maximum control of the plant. The plant automatically returns any effluent that is out of spec to the balance tank to be reprocessed. A pH probe and turbidity monitor were installed and an alarm provided in the event that the effluent was out of specification.
In addition to the compliant effluent result, Aerofloat’s design was compact and had a minimal environmental footprint. Its sealed and vented tanks created an odourless plant, and the mechanical simplicity of the design, with its self-cleaning hopper bottom, ensured a maintenance-friendly system.
Meat manufacturer Meyer Food Co. utilised Aerofloat’s AeroDAF to ensure compliancy for its meat processing facility.
Circular Plastics Australia’s new plant in Altona North, Victoria, will recycle high-density polyethylene (HDPE) and polypropylene (PP) plastics from the Melbourne community. It required a wastewater treatment solution that would meet Melbourne city’s strict trade waste requirements.
Circular Plastics Australia’s new plant in Laverton, Victoria, required a wastewater treatment solution that would meet Melbourne city’s strict trade waste requirements. Aerofloat has worked with Circular Plastics Australia on multiple projects to ensure compliant wastewater.
