Atlas Iron awarded Maca a contract to carry out an open-pit mining at the Corunna Downs iron ore project in the Pilbara of Western Australia. Client: Maca Location: Pilbara region of Western Australia Technology implemented: Ecofarmer 50 series wastewater treatment plant Industry: Mining BACKGROUND The project, some 33 km south of Marble Bar in the Pilbara, will see Atlas develop five open pits using conventional drill and blast, and load and haul methods. Some 23.3 Mt of iron ore will be mined above the water table over an approximate timeframe of six years, according to a filing with the Environmental Protection Authority. Our dealer RWWA have designed a custom Ecofarmer 50 wastewater treatment plant to cater for mining administration areas. THE RWWA SOLUTION 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 custom design wastewater treatment plant that caters for mining administration areas and met all council regulations and had a positive impact on the surrounding environment. Ecofarmer Australia dealers ALWAYS delivers environmental sustainability to all sites, by ensuring wastewater treatment plants are always in compliance to minimise environmental impact and other sensitive environmental water matters.
