Hydroflux is a leading provider of tailored water treatment solutions. With extensive experience and expertise, we specialise in developing customised solutions that address the unique water treatment needs of each site and operation.

Our team understands the complexities of water treatment and the unique conditions faced in mining. No operations and processes are identical and as such, we believe in the importance of tailored solutions. We work closely with the with each operation to develop optimised treatment solutions uniquely designed to suit site conditions and operational needs.

We have designed water treatment solutions for various aspects of a mine’s operational requirements. This includes treatment of process water, potable water and wastewater treatment for onsite operation and mining camps. Our equipment and systems are built to be extremely robust with minimal maintenance to take into account the harsh environment and remoteness of many operations.

The Hydroflux team brings decades of experience in water treatment and a deep understanding of the requirements in the mining sector. Our team consists of dedicated project managers, process and mechanical engineers, electrical & automation and technical support engineers. This multidisciplinary approach enables us to offer end to end solution for your project and direct ongoing support with experts who are familiar with your project and requirements.

Water plays a vital role in various processes, streams, and critical operations within each operation. The significance of water becomes even more pronounced considering the remote and harsh environmental conditions in which mine sites are often located, along with the challenges of water availability.

Hydroflux specialises in providing customised solutions to address all aspects of a mining operation, including:

  • Process water treatment. Maximising recycle and treatment for application for dedicated systems which may otherwise require a cleaner water source (i.e. raw water, potable water)
  • Raw water, bore water, potable water treatment plants. Removal of contaminants for dedicated process systems or critical operations (i.e. safety showers, washdown, facilities)
  • Waste water treatment systems, for facilities and camps.
  • Tailings management
  • Environmental discharge & regulatory compliance
  • Mine remediation

We understand that each operation is unique, in its process, operations, location and environmental requirements. We approach each project collaboratively with a tailored and engineered approach, utilising proven technologies to provide a solution that meets and exceeds performance requirements, whilst remaining cost effective and a focus on minimising maintenance and maximising availability.

Some of our technology scope includes:

Potable water is perhaps one of the most valued water on site. Potable water supplies operations with their drinking water, site amenities, safety equipment and specific process systems (i.e. safety showers, gland water, chemical batching).  Hydroflux provides complete, onsite potable water treatment solutions customised to your water source.

Groundwater is a common source for many potable water treatments that Hydroflux supplies. The quality of ground water can vary depending on the location and the geological characteristics of the surrounding soil and rock formations. In some areas, the groundwater may have a high level of salinity due to the presence of dissolved minerals and salts, making it brackish. A typical process which Hydroflux employs for treatment includes:

Depending on your water source:

  • For high turbidity, the initial stage of treatment will usually involve chemical coagulation followed by clarification. This process aims to remove suspended solids and particles from the water, enhancing its clarity and reducing turbidity.
  • For non-brackish water with low levels of dissolved salts, the secondary and final treatment approach involves media filtration followed by disinfection. Media filtration effectively removes impurities and particulate matter from the water, while disinfection destroys harmful microorganisms, ensuring the production of potable water.
  • For brackish water, a popular method of treatment is the utilisation of reverse osmosis (RO). This involves passing the brackish water through a semi-permeable membrane to effectively remove dissolved solids and salts. Reverse osmosis is highly efficient, capable of removing up to 99% of salts and minerals present in brackish water. Hydroflux can also incorporate Ion Exchange technology for similar purposes, utilising a resin bed that facilitates the exchange of ions.

Hydroflux can provide your full potable water treatment solutions tailored to your operation requirements, containerised or skid mounted for easy installation and operations.

Most mines are situated in remote areas and to extreme conditions with sensitive environments and shared water resources. Wastewater treatment of onsite facilities and camps must incorporate water treatment solutions that are efficient and allow for ecological restoration and include monitoring. They must also consider fluctuations in water supply and varying contaminants. For many operations, treatment demands can include effluent to be reused in onsite amenities.

Hydroflux have been designing, developing and supplying wastewater treatment plants for over 60 years. Hydroflux’s RoadTrain activated sludge plant is one of the most robust and simple to operate wastewater treatment plants, designed specifically for remote operations and highly customisable to accommodate various needs, capacities, conditions and local water supply.

The original RoadTrain have been installed in the mining industry since the 1960s with upgraded versions still supplied and heavily favored among our clients today due to its customisation and scalability. RoadTrains were installed in the Bowen Basin coal mine, located in central Queensland in the 1970s designed to cater for 400 people. After a series of relocations and upgrades, it accommodates for up to 800 people in 2012.

Today, the RoadTrain range offers several options from activated sludge treat process to enhanced nutrient removal. Diagram and specifications of the original RoadTrain and its variations today can be found in the gallery below and through this link. The RoadTrain has also been engineered in pre-fabricated systems that can be simply bolted to a concrete slab. They arrive to site in a flat pack system reducing logistical issues for sites with minimal road access or absence of cranes. This was the case for a bolted RoadTrain that was installed at Moro village within the Oilsearch mining lease in the Papua New Guinea southern highlands in 2015.
