Mining Water Treatment

Tailored Water Treatment Solutions for Mining Operations

For mining operations, water is the most precious commodity and the supply of clean water is critical for essential processes, services, and daily operations. Hydroflux provides customised solutions to address all aspects of a mining operation, including:

• Ground & process water treatment.
• Tailings, wastewater treatment.
• Potable water treatment.
• Sewage wastewater treatment.
• Environmental discharge & regulatory compliance.
• Mine remediation.
• Recycling and Reuse

With extensive experience and expertise, we specialise in developing tailored water and wastewater treatment solutions that address the unique water needs of each mine site and its operations. 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 each operation to develop optimised treatment solutions which are uniquely designed to suit site conditions and operational needs.

Comprehensive Solutions for Process and Tailings Water Treatment

Over the past decade, the demand for treatment plants capable of producing high-quality treated water for recovery, reuse, and compliant environmental discharge at mine sites has significantly increased, particularly for end-of-life mining operations. Effective treatment of process water and tailings management is essential for minimising environmental impact, ensuring regulatory compliance, and maximising water reuse.

Hydroflux provides comprehensive solutions for process and tailings water treatment, offering turnkey plants and system upgrades that integrate seamlessly with existing infrastructure. Our treatment systems are designed to manage complex challenges, including high suspended solids, heavy metals, sulfates, nitrates, and other contaminants. Recognising that every mining operation is unique, we take a collaborative, tailored approach, leveraging proven technologies to deliver cost-effective, low-maintenance solutions that maximise system performance and availability while meeting stringent environmental standards.

Some of our key processes and technologies include:

Effective water management is essential for the sustainability and operational efficiency of mining projects. Hydroflux is Australia’s leading water treatment company committed to advancing the sustainability of mining operations through innovative water treatment technologies and solutions.

Fully Customised, On-Site Potable Water Treatment Solutions

Potable water is one of the most critical resources on site, supplying drinking water, site amenities, safety equipment, and essential process systems such as safety showers, gland water, and chemical batching. Hydroflux provides fully customised, on-site potable water treatment solutions tailored to the specific water source and site requirements.

Groundwater is a common source for potable water treatment, but its quality varies depending on location and geological conditions. In some areas, high levels of dissolved minerals and salts can result in brackish water, requiring specialised treatment. Hydroflux designs and implements tailored treatment processes to ensure safe, high-quality potable water, typically incorporating the following process elements.

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.

Decades of Expertise in Mining Sewage Treatment

Most mines are located in remote areas with extreme conditions, sensitive environments, and shared water resources. Wastewater treatment for onsite facilities and camps must be efficient, adaptable to fluctuating water supplies and varying contaminants, and designed to support ecological restoration and monitoring, and in many operations, treated effluent is also required for reuse in onsite amenities.

With over 60 years of experience, Hydroflux has been at the forefront of designing, developing, and supplying advanced wastewater treatment plants for the mining sector. The Hydroflux RoadTrain activated sludge plant is a highly robust and easy-to-operate system, specifically engineered for remote operations. Its customisable design allows it to meet diverse capacity requirements, site conditions, and local water supply variations, ensuring reliable and efficient wastewater management even in the most challenging environments.

A Proven Track Record Since the 1960s

The RoadTrain has been a trusted wastewater treatment solution in the mining industry since the 1960s. Upgraded versions continue to be supplied today, remaining a preferred choice among clients due to their scalability and adaptability. One notable installation was at the Bowen Basin coal mine in central Queensland during the 1970s. Initially designed for 400 people, the system underwent multiple relocations and upgrades, eventually accommodating up to 800 people by 2012.

Today, the RoadTrain range includes various options, from standard activated sludge treatment to advanced nutrient removal systems.
