Mining and Primary Metals

We employ specialised technologies to provide reliable and cost-effective solutions that maximise productivity, minimise downtime, and meet your environmental discharge requirements using a rage of proven and established process operations including screens, clarifiers, oil separators, chemical handling and dosing equipment, DAF systems, various types of filtration and membrane plant and solids handling equipment. The following diagram shows a typical primary treatment processes using clarification.

Key application areas include:

• • Raw material recovery

• • Contaminant removal

• • Regulatory Compliance

• • Tailings Management

• • Environmental Discharge

• • Mine site remediation and treatment of wastewater

Hydroflux Industrial work collaboratively with our clients environmental and engineering teams early in the planning phase to ensure all options and risks are identified before providing a solution to meet your projects objectives.

Regardless of the nature of your local water source, we can design a mine water treatment plant that provides a consistent supply of water that meets your operational needs. Our pre-water treatment systems deliver process water to mining facilities in remote locations across Australia and New Zealand, ensuring uninterrupted operations to maximise profitability.

Process Water & Reuse Solutions

Water is a key component to all successful mining operations. Due to the remote locations where mining operations are located, availability of reliable and sustainable water sources is critical for the long term viability of any mine site. Site operations produce wastewater which include a wide range of inorganic contaminants. Hydroflux inhouse design and construction of advanced water reuse solutions provides our mining partners with options to reuse water from virtually any source on site.

Hydroflux evaporation and zero liquid discharge solutions also allows mines to recover and reuse 95 – 99% of their process water.

Hydroflux Solutions

Hydroflux have a range of proven, highly efficient process and advanced water solutions for the manufacturing sector, including:

• Specialised selective membrane and ion exchange systems for advanced water reuse
• Tailings Dam Reuse
• Acid Mine Drainage treatment & Reuse
• Seawater desalination
• Bore water treatment systems
• Ultrafiltration & Reverse Osmosis
• Ion Exchange & Electrodeionization for high purity water production
• Evaporation & Zero Liquid Discharge

Design and Construct solutions for Process and Recycled Water Treatment

As a specialist in both water treatment and wastewater treatment, our team are uniquely placed to offer complete support for all water services. We understand how process water management impacts on mine production efficiency and operating costs. Due to our capability to offer complete water project solutions in house and also execute complex site construction works, procuring the complete design and construction scope through Hydroflux provides significant benefits to our partners in the mining Industry. Sourcing the design and construction scope for a water treatment specialist avoids significant performance risk and reduces project costs.

Our team are familiar with the typical safety, civil, mechanical and electrical standards applied on mining sites. Hydroflux’s ability to integrate our own high standards for equipment design and safety with our partners specific site engineering standards means the best possible outcome for the finished project.

Hydroflux designs and models all water and wastewater treatment plants in 3D

The utilities division provides the link to integrating the Hydroflux® businesses by providing a comprehensive support network for customers throughout New Zealand.

Hydroflux Utilities provides virtually any form of wastewater management programs including:

Chemical optimisation

Hydroflux has a comprehensive range of coagulant and flocculants suitable for conditioning water, wastewater or sludge. The most appropriate chemical program will be determined before commissioning based on experience, or test work if possible, and long-term cost-effective chemical supply contracts can be arranged.

Preventative maintenance and service

Our engineers and technicians will discuss service and maintenance programs with you during construction of the treatment plant so that you can be assured that the system will perform consistently from day one. There are many types of programs available from routine preventative maintenance, periodic

service and overhauls, to complete plant operation. Our technicians are available 24/7 to attend to unforeseen breakdowns.

Biological plant modelling and remote monitoring

Hydroflux designs, operates and maintains biological wastewater treatment plants and we are familiar with the many causes of failure and malfunction.  Via routine site attendance or online remote monitoring of the  biological operating parameters, Hydroflux engineers can predict potential process issues to minimise any impact on the performance of the plant or prevent even problems from happening.
