Engineered waste water treatment plant for the OZ minerals project

RWTS were successfully awarded the head contract to design and construct a suitable engineered waste water treatment plant for the OZ minerals project in Carapateena South Australia.

 

Client: OZ Minerals

Location: Carapateena South Australia

Technology implemented: EcoFarmer 250

Industry: Mining

 

BACKGROUND

The OZ minerals camp design life was for 20 years with a 450 peak manning accommodation and mine services administration facility attached. OZ Minerals required a waste water treatment plant solution to facilitate the accomodation water service needs. The Remote Water Treatment solutions experts designed the arrangement of a containerised Ecofarmer 250 platform. The modular sequence was required to be constructed to accomodate the wastewater for the project over the construction phase into permanent accommodation.

THE RWTS SOLUTION

ECOFARMER 250

To achieve the project scope a centralised johnson wire screened raw sewage drew from the camp. Then screened fluid was transferred to the combined balance holding tank and the sequencing of the SBR trains allowed fluid to enter the biological treatment phase. Treated water chlorinated was dispersed on to the designated land application area. RWTS executed the project within the intended time line and meet all government approvals and certification. South Australia health requirements and submissions strictly state that all tankage must be structurally engineered and process certified. RWTS had the steel fabricated shells engineered and process reviewed certified by third party. RPEQ process engineering team, used sophisticated modelling software to achieve a suitable final effluent stream.

 

RESULTS

All equipment and hardware used on the project was of high standard and supported in the Australian markets giving RWTS clients the peace of mind that the equipment is built and deigned to the highest of standards.

Engineered water treatment system for the township of Linville: SEQWater

RWTS were subcontracted by SEQWater to design and manufacture a engineered water treatment system for the township of Linville. 

 

Client: Practical Engineering and SEQwater

Location: Linville municipal water treatment plant

Technology implemented: Engineered water treatment system for the township of Linville

Industry: Infrastructure

 

BACKGROUND

Due to the 2013 floods and changes in raw water from the Bores supplying the original Linville Water Treatment System, the Linville township potable quality of water could not be guaranteed. As a consequence of the environmental changes that were affecting the Linville township water quality the original water treatment system needed to be decommissioned. In the past seven years as an interim solution the potable water from Kilcoy Potable Water Treatment Plant was trucked in and pumped into the town reservoir which serviced the town requirements. This was not going to be sustainable in the long run and thus RWTS was engaged to provide a water treatment solution to meet the township long term needs and requirements.

CHALLENGES

Due to the non release site, a minimal waste water was being generated; which resulted in common back washable filter types not being a viable option.

THE RWTS SOLUTION

FILTRATION | ULTRAVIOLET DISINFECTION SYSTEM

RWTS partnered with Practical Engineering – a specialist project team who were given the opportunity to construct a purpose designed and engineered water treatment facility and compound. The Water treatment process required by SEQwater had strict specifications and needed to meet a specific virus and protozoa log reduction through various forms of treatment application and disinfection packages.

RWTS proposed a validated absolute replaceable cartridge filtration process with no backwashing requirement, validated Ultraviolet Disinfection System treatment and residual chlorine disinfection equipment. SEQwater process engineers agreed to the proposed process offered and the design was signed off as a viable solution for the township of Linville. RWTS was engaged and responsible for the turn key water treatment process, procurement, engineering, installation, commissioning and operator training hand over package to client.

Work commenced in late 2019 and was successfully completed in April 2020 after extensive performance testing was completed over a period of 6 weeks.

RESULTS

The Linville township was successfully supplied by RWTS with treated potable water via a custom designed turn-key potable water treatment system. The  water treatment system RWTS implemented provided a high quality potable water source conforming to the Australian Drinking Water Guidelines standards and strict guidelines outlined by the utility provider SEQwater.
