The Situation


Operational practice at the client’s alumina refinery is to use hoses on washer underflow to assist with pumping performance.

The practice was recognised as having a cost to the business but was perceived to be required due to the condition of the equipment and nature of the slurry being pumped. 




Under the umbrella of a broad refinery wide technical service agreement Advisian identified this practice as an opportunity for improvement and quantified the business impact. 

Advisian’s scope was then to work with the client’s operations team to deliver sustained reductions in hose water usage.  

Our Solution


The methodology adopted by Advisian was key to driving success. Goals were set, KPI monitoring established, procedures and routines updated, operator training provided. A culture of shared ownership and responsibility with the site team was actively promoted and developed.

The project was delivered in three weeks. USD $1M per annum caustic savings were delivered, exceeding expectations.

The improvements have been sustained when audited at a later date. Client feedback was overwhelmingly positive.
