Atlas Iron awarded Maca a contract to carry out open pit mining services at the Corunna Downs iron project in the Pilbara region of Western Australia.

Client: Maca

Location: Pilbara region of Western Australia

Technology implemented: Ecofarmer 50 series wastewater treatment plant

Industry: Mining

 

BACKGROUND

Corunna Downs, which is 100 per cent owned by Atlas Iron, is 33 kilometres south of Marble Bar and close to the iron ore miner’s Mt Webber project. The mine is expected to annually produce four million tonnes of iron ore initially. The life of the mine is expected to be between five and six years, with potential for future expansion as the current ore reserve considers only the above-water table resource.

Remote Water Treatment Services have designed in their custom Ecofarmer fabricated engineered reactor a waste water treatment system to cater for mining administration areas, ideal for low flow scenarios.

THE RWTS SOLUTION

Ecofarmer 50

waste water treatment system

The design known as the Ecofarmer 50 SBR caters for flows as low as 2,000 l – 10,000 l per day, an extremely versatile waste water treatment plant for the demand and environment.

The waste water treatment system takes it’s design and methodology from big brother the Ecofarmer 250, with the main process pump and motors located in the plant room, no moving parts are internal of the reactor allowing for ease of servicing.

The Ecofarmer design offers a treatment process with carbon and alkalinity supplementation dosed through our grundfos dosing platform controlled through the human–machine interface (HMI) ensuring optimal nutrient balancing through low demand periods. The system program looks for the level within the balance chamber automatically adjusting the cyclic nature of the process to achieve the desired aeration/mixing cycles. Further to this we have offered in our base offering a uninterruptible power supply (UPS) and Ewon remote modem for remote access into the programmable logic controller (PLC) and Human–Machine Interface (HMI), we can update software remotely and assist site based operators with handling issues that may arise without a call out fee.

Result

A waste water treatment system that caters for mining administration areas and met all council regulations and had a positive impact on the surrounding environment.

RWTS structurally engineered containerised plug and play Ecofarmer system was installed with in 5 days of mobilisation. The system is backed by RWTS remote dial in logging platform to allow our staff to maintain and record plant parameters from our Brisbane based office assisting our clients site operations.

Location:Fitzroy River, Central Queensland

Technology implemented: Twin train Ecofarmer 250 series wastewater treatment plant

Industry: Agricultural

 

BACKGROUND

Accionia were awarded the contract to construct the Rookwood Weir as part of the Fitzroy river catchment development plan through Sunwater.

Working along side Black Diamond Project Group to construct a workers accommodation village to accommodate 250 workers through the construction phase of the project saw the need for waste water and water treatment to maintain vital village services.

Remote Water Treatment Services were successfully awarded a design and construct project to action a suitable wastewater treatment plant to cater for the Fitzroy River village waste water requirements.

THE RWTS SOLUTION

Ecofarmer 250

RWTS provided a twin train Ecofarmer 250 series wastewater treatment system to cater for the village waste water requirements. We also completed the design and implemented the irrigation field evenly dispersing the treated water over 50 000 m2 through supported wastewater distribution networks.

In addition RWTS provided the potable water treatment system to cater for the village demands, raw water is to be harvested from the lower Fitzroy region and delivered to the raw water storage tanks. As water is required for consumption through the camp the treatment process commences operation passing water through the array of water treatment specialty filtration modules and stored in treated water storage tanks. Water in the treated water storage tanks is continuously recirculated and monitored for Chlorine, Ph, conductivity and turbidity. RWTS also sized and installed the main village reticulation pumps ensuring potable water delivery to the village on demand.

The solution simple, from harvesting raw water to making treated water conforming to the Australian Drinking Water Guidelines (ADWG) to then gathering and treating the waste water and dispersing on to land.

As part of RWTS service offering we provided a turn key solution for all our clients project water treatment needs.

RWTS were awarded the contract by client Santos cooper basin projects to deliver an engineered wastewater treatment system catering for their remote camps waste water needs out at Tarbat operations, Queensland.

Client: Santos

Location: Tarbat Queensland.

Technology implemented: EcoFarmer 50

Industry: Mining

BACKGROUND

Due to the ever flocculating camp numbers (as low as 15 to 50 ep), the process of  converting the BOD and Nitrogen loadings placed on the plant was a challenge.

THE RWTS SOLUTION

The RWTS process team overcame the issue by utilising a biological additive yielding 900mg/ kilo of mass dosed through our dosing system set up. The results allow for a constant and stable mixed liquor within the aeration chambers vital to the growth of essential bacteria.

The wastewater treatment system was completed within the confines of an international shipping container, making for seamless road transportation. Built from the ground up and structurally certified, the wastewater treatment system was the perfect fit for the environment. The hand rails and ladder system were compliant to code, thus allowing for safe height access. Furthermore, the turnkey design minimised the commissioning process so allowed the camp to continue business-as-usual operations while the plant was installed for remote camp tenants by 6 pm.

RESULTS

The treated effluent was then dispersed on the lease via sprinkler system and compliant to the overarching Environmentally Relevant Activity (ERA) as set out by the Queensland Department of Health.

Wastewater Storage vs. Onsite Wastewater Treatment For Mining

Are you curious as to whether it’s worth investing in onsite wastewater treatment for your project or simply storing wastewater before pumping offsite? We’ve been asked this question time and time again, so we’ve weighed up the pros and cons of each management method to help you decide.

Water management plays an integral role in the seamless day-to-day operations of any remote site, particularly an accommodation camp within the mining sector.

Water is an essential resource when it comes to:

 

  • cooking,
  • cleaning,
  • operating amenities such as showers, taps and toilets,
  • vehicle wash bays,
  • and most importantly, providing safe drinking water.

It’s no mystery then, that wastewater is an inevitable by-product of the extensive water usage on remote sites. In the early stages of planning any accommodation village, the pressing question of how this wastewater will be dealt with arises.

There are two primary options on the table:

1. Integrating an onsite sewage treatment plant

2. Storing wastewater for offsite treatment

There is no hard and fast rule when it comes to choosing which option is best suited to your site, but we’ve discussed a few key factors to consider. The table below very generally captures the best option based on these factors.

 

Water Storage vs. Water Treatment Matrix

1. TIME

How long is your site realistically going to be in operation?

Short-term

A short-term site with a lifespan of just 1-8 months will likely see greater benefit in water storage.

Why?

 

  • Reduced capital investment – Any water treatment plant will likely not in operation for long enough to offset the greater investment of such a system.
  • Rapid deployment – Water storage options such as tanks or the WaterBox, offer the advantage of rapid deployment. These are pre-packaged products that can be transported to site on short notice.
  • Environmental approval takes time – A tailored wastewater treatment system requires environmental approval from the state’s environmental regulatory body in order to discharge effluent onsite. This is often a time-intensive process and, depending on the terrain of your site, may not be feasible for your site or project timeline.

Long-term

If your site will be in operation for longer than 8-12 months, looking to an onsite wastewater treatment plant will likely be worth your while.

Why?

 

  • Pump-out fees will be too expensive – Although a more costly investment upfront, by integrating a wastewater treatment system you will be forgoing the costly pump-out fees of transporting your wastewater to an approved discharge location. This may be justified on a short-term project, but over time this will chew through the budget significantly.
  • Treated wastewater can be reused – Depending on your site, the treated wastewater can be used for local irrigation, reducing the demand on potable water.

 

2. Environmental Regulation

Environmental bodies have rigid regulations when it comes to discharging treated wastewater to the land. This can make the process of having a wastewater treatment plant approved a difficult endeavour, and even impossible when the terrain is not permissive of irrigation (e.g. close proximity to a bore, watercourse, wetland or spring).

Should your plans not comply with regulation, wastewater storage may be your only option.

3. MOBILITY

Mobile

Is your camp likely to be relocating on a regular basis? If so, a wastewater storage solution will be the better option. The WaterBox has been optimised for such circumstances and can be relocated with a 12-tonne forklift or crane. It’s shipping container design also lends it to easy compatibility with any truck/train transport.

Fixed

Wastewater treatment systems tend to be far more difficult to relocate, and commission and decommission. Taking all other factors into consideration, these are far better suited to camps that will be in a fixed location for a prolonged period.

If you are looking for a turnkey wastewater treatment system that can move with your camp, discover the EcoFarmer.

 

4. CAMP SIZE

Similar to the factor of time, the size of your remote camp will impact the volume of wastewater produced.

Small

For a small camp consisting of up to 100 people, less wastewater will generally be produced and therefore, wastewater storage may be more feasible.

Large

For a larger camp accommodating over 100 people, the volume of wastewater produced would likely be in excess of what mere storage could handle. This increased load would lend itself to a wastewater treatment solution being integrated.

 

5. COST

At this point, you’ll understand that many factors will impact the cost of a wastewater management system, but generally:

 

  • for a short-term or mobile project, wastewater storage will be more cost-effective.
  • for a long-term, fixed project, onsite wastewater treatment will be more cost-effective.

Below we’ve outlined the primary costs (other than the cost of the system itself) associated with each option:

Wastewater Storage

 

  • Wastewater pump out – Only licensed liquid waste transport operators can legally transfer wastewater to an external facility. Due to the environmental, public health and workplace safety risks of transporting such high volumes of sewage, the cost of liquid waste removal services can be extremely high.

Wastewater Treatment System 

 

  • System maintenance – A wastewater treatment plant will require regular maintenance to ensure the ongoing efficiency of the system. Neglected plants with built up residue will eventually break down and require expensive repairs or replacement. We recommend a cleaning-in-place (CIP) system to ensure the long-term health of your plant.
  • Chemicals and consumables – In order to treat the wastewater, chemical dosing is generally required. Therefore, there is an ongoing cost of ensuring there is sufficient inventory to keep the system in operation.
