SciDev to supply Peabody’s Wilpinjong coal mine with OptiFlow system

SciDev Ltd has signed a two-year contract with Peabody Energy, the world’s largest non-government coal mining company, for the supply of an OptiFlox® system and associated chemicals at the 12 million tpy Wilpinjong thermal coal mine in New South Wales, Australia.

The total value of the contract is estimated to be AUS$350 000 – AUS$400 000 per annum and significantly strengthens SciDev’s growing revenue base. Peabody will pay a monthly leasing fee for use of the OptiFlox system at Wilpinjong, along with the purchase of associated wastewater treatment chemicals.


The Wilpinjong contract formalises the relationship with Peabody and follows the successful installation of an OptiFlox Mark-2 system at Wilpinjong in December 2016, after a successful six-month trial at the facility. The success of the Wilpinjong trial has resulted in an increased level of industry interest in the OptiFlox system.


The OptiFlox system is designed to address the issue of ‘blackwater’ in which the clarity of the water from a coal tailings’ thickener deteriorates to an unacceptable level, resulting in the coal washing plant shutting down and at times, coal production ceasing.


The OptiFlox system continuously measures particle characteristics of the coal tailings slurry in order to maintain optimal flocculation conditions through automated, real-time control of coagulant dosing. The system minimises delays and stoppages in production, caused by ‘blackwater’, and enables consistent clarified water to be produced for return to the washing plant.


To support the contract with Peabody and develop further business in NSW, the company has appointed an executive with considerable experience in industrial waste water treatment, particularly in the NSW coal, metalliferous and quarrying industries. This executive will be based in the Hunter Valley and will have responsibility for servicing the Wilpinjong contract and expanding SciDev sales in extractive industries in NSW, with a principal focus on the coal industry.
