The ultra-filtration plant is housed in a standard 20′ shipping container. Effluent from the main plant is diverted from existing irrigation tanks to a closed loop filtration process where it is pumped through a membrane module under controlled conditions. The resultant filtrate is monitored for turbidity and sterilised with both ultraviolet light and traditional chlorination before being stored for re-use.

The shipping container houses the membrane module as well as the switchboard, automatic valves, clean in place tank, pumps and associated instrumentation.

Masig Island (Yorke Island) is a coral cay situated in the Torres Strait at the top end of the Great Barrier Reef surrounded by pristine aquamarine seas, rich in marine life. The sea has always been integral to the way of life of the Masig islanders. Commercial mackerel fishing, prawning and crayfishing is undertaken and a highly profitable fish factory has operated on the island since the late 1970’s. Currently trials are underway on a potential sea sponge aquaculture industry.

In 2007 EPCO Australia was awarded the contract for the development of a new wastewater treatment plant on Masig Island as part of the Torres Strait Islands Major Infrastructure Program which is delivering environmental health infrastructure to Torres Strait communities.

Due to the environmental sensitivity of the area, the plant had to meet a B class discharge quality requirement, namely <20mg/L BOD, <30mg/L suspended solids, <15mg/L nitrogen, <8mg/L phosphorous and <150 CFU on a 50th percentile basis.

The wastewater treatment plant installed by EPCO Australia included biological and tertiary treatment and was designed for a sewage flow of up to 135m³/day. The treatment system included flow metering, fine screening, aerated balance tank, Imhoff stage, RBC stage, final settling, tertiary filtration and UV disinfection.

A tertiary filter has been fitted to provide A class for reuse if required.

As part of this project, local indigenous workers were employed to assist with installation of the equipment and were later given Certificate III Level training in sewage treatment plant operation and maintenance. These operators, with first-hand knowledge of the equipment and a personal interest in maintaining it, will ensure the sustainability of the project.

This project will have substantial and tangible impacts on the health, quality of life, and overall community sustainability of the Masig Island area.

Aeration equipment is vital to the biological operation of aerobic wastewater purification processes. Aeration introduces oxygen into the treatment process which is essential in sustaining the beneficial bacteria that consume the pollutants in the wastewater. If you have a requirement for reliable, energy efficient aeration, then the solution may be the EEE High Speed Floating Aerator.

A simple design with a low weight makes the unit easy to launch and it requires only mooring cables and a power supply to make it operable. This means that you will have greatly improved quality of wastewater in a very short time. The EEE aerators are well suited to aeration basins, sludge tanks, treated effluent ponds and leachate lagoons.

A better water flow begins with better streamlining. Computer-aided design and unitized fiberglass construction provides the smoothest curved intake, volute and discharge passage possible. The ergonomical shape allows for an efficient pumping flow rate – 969lps delivered by a 15kW EEE model compared to 524lps by a competitors 15kW model. Greater efficiency means ultimate savings in operational costs.

The EEE diffuser is larger in diameter to eliminate spray-back that could freeze up and corrode the motor as has been found to be the case in other aerator designs. All EEE aerators have large diffusers – the result of extensive engineering research – and these diffusers offer a number of important advantages:

• The large EEE diffuser provides more surface for the inrushing water to follow
• The spray is less susceptible to wind drift
• The weight of the EEE diffuser minimizes vibration which means less wear and tear on components and a longer operating life.

EEE aerators have been effectively utilised over a wide range of applications:

• Municipal water treatment
• Industrial wastewater treatment
• Fish farming
• Pulp and paper mills
• Fruit and vegetable industry, dairy and cheese industry
• Petrochemical industry
• Wineries
• Camp grounds
• Motels

The EEE Aerator is the most effective, energy efficient aerator available and the most affordable. Simplified design and creative engineering have produced a superior product that you can rely on.

By now you may have received a brochure from The Queensland Department of Environment and Heritage Protection announcing changes to compliance and monitoring of environmental standards.

Do you know what your compliance obligations are?

Does your process and equipment meet those obligations?

The department is changing the way it regulates by:

• Upgrading systems to increase data collection and analysis
• Expanding the compliance team to spend more time inspecting to ensure businesses are meeting their obligations.
• Increasing penalties, up to four fold for individuals and corporations that don’t comply.

EPCO Australia offers compliance assistance

EPCO Australia has teamed up with it’s strategic partner Simmonds & Bristow to offer an audit service to help our clients meet the new compliance regime.

Depending on your audit choice, our review will:

• Evaluate your licenced obligations
• Compare licence compliance with facility
• Review staff competence and procedures
• Review your process, the equipment, it’s condition
• Provide you with a costed report to enable effective implementation.

If the audit leads to further engagement for EPCO or Simmonds & Bristow, up to half the cost of the associated audit will be deducted from the cost of the further engagement.

Audits available:

• Process and compliance
• Equipment and effectiveness
• Process and Equipment combined

Could your business afford the disruption of non-compliance?

If your answer is NO then contact us now for assistance to meet your licenced obligations.
