Our Technologies

The activated Minerals Extraction System, or aMES® is an innovative process technology that enables the treatment of concentrated aqueous solutions to recover a range of valuable minerals, reagents and fresh water. The technology has applications in the desalination, energy, mining and industrial sectors.

ADVANTAGES

The aMES® technology incorporates several novel innovations into an integrated process delivering significant advantages over conventional technologies including:

• Improvements in mineral recovery and product quality
• Opportunity for substantial project capex & opex savings
• Highly efficient use of energy and produces pure water as a by-product
• Reduced water consumption
• Improved project footprint and environmental sustainability

APPLICATIONS

The ability of the aMES® technology to dewater extremely concentrated solutions including brines, and concurrently recover fractionated products, is highly desirable in a range of applications including:

• Energy – dewatering coproduced waters (recovering minerals)
• Mining – natural brine & solution mining (lithium and potash bearing deposits)
• Mining – downstream refinery wastes (cobalt, copper, nickel, REE’s and/or reagents)
• Wastewater – dewatering (to recover dissolved solids, TDS, as product/s)

The integrated Brine Causticisation, or iBC® is an innovative process technology that removes common impurities from waste brine streams enabling further processing.

The purified brine stream is subsequently treated in an integrated process, resulting in the production of various salt products and industrial-grade sodium hydroxide.

ADVANTAGES

The iBC® technology incorporates several novel innovations into an integrated process delivering significant advantages over conventional technologies including:

• Conversion of problematic impurities into products
• Enabler of further downstream processing, reducing waste brine volumes
• Recovery of water and salts into saleable products

APPLICATIONS

The ability of the iBC® technology to convert problematic carbonates and bicarbonates in brines, and concurrently recover products, is highly desirable in a range of applications including:

• Energy – dewatering coproduced waters (recovering minerals)
• Mining – natural brine & solution mining (recovering minerals)
• Mining – downstream refinery wastes (recovering minerals & reagents)
• Wastewater – dewatering (to recover dissolved solids, TDS, as product/s)

Leachate generated from municipal landfills is presenting an increasing challenge for operators, particularly when contaminated with PFAS and related contaminants.

Through a portfolio conventional and proprietary technologies, Parkway is able to deliver an effective leachate treatment solution.

ADVANTAGE

• The ability to tailor a solution that best suits the requirements of a given project
• Experience with both conventional and next-generation technologies
• The flexibility to adopt a staged approach where initial biological treatment and dewatering processes can occur immediately, providing immediate relief, whilst downstream processing options are evaluated to develop a full-lifecycle solution to leachate waste management.

APPLICATIONS

The ability of our Leachate & PFAS solutions to be customised for a given feedstock, enables our solutions to be applied to wide range of liquid waste streams including:

• Contaminated groundwaters
• Industrial landfill leachate
• Municipal landfill leachate
