Aerofloat designed a simple washwater treatment plant for Astron Plastics and formed a lasting relationship with PACT Group.

Aerofloat was able to quickly identify a simple and cost-effective treatment plant to meet the client’s need.

The Need

Astron was after a solution that provided lower turbidity water for washing of its plastics, reduced odour of its water and overall plant, and a bag dewatering system to allow sludge to be disposed of in a skip rather than liquid waste in an IBC.

The Solution

Aerofloat custom designed a wastewater treatment solution to treat Astron Plastics wash water by using its patented dissolved air flotation unit, the AeroDAF 100.

The Benefit

A successful trial and final project, that achieved the agreed success criteria of lower turbidity water, reduced odour and a manageable sludge dewatering solution.

Background

Astron Plastics’ Sydney plastic recycling plant required a wastewater treatment solution. Astron Plastics is part of the PACT Group.

The plant does not recycle post-consumer plastics but does recycle old and damaged garbage and recycling bins. As such, the wash water quality is not as readily contaminated as that from other plastics recyclers Aerofloat has worked with.

The Aerofloat Solution

Aerofloat was able to install a simple, cost-effective recirculating wastewater treatment system on a trial basis for Astron Plastics.

Aerofloat designed, installed and commissioned a wastewater treatment plant that included Aerofloat’s proprietary moving bed biofilm reactor AeroMBBR, a 3m3/h dissolved air flotation (AeroDAF) unit and a bag sludge dewatering system.

Results

Following the successful trial implementation of this plant in meeting the specified performance criteria, Astron has agreed to purchase the system.

Aerofloat is excited about the new design option it has created for the plastics recycling industry. Aerofloat is seen as a leader in wastewater treatment for the plastics recycling industry and received a GreenTech Consensus Award in December 2019 for its achievements in this area.

After Care Service

Aerofloat can help you maintain optimal performance of your wastewater treatment system long after installation.
