Treated Water Boost Pumps

Glencore's Oaky Creek Coal (OCC) operation uses recycled water treated within an onsite RO plant to provide treated water for use by various operations on site. OCC recognised an opportunity to use this clean treated water for water supply to critical equipment such as Horizontal Belt Filters (HBF), improving the quality of water used for equipment, reducing downtime and maintenance requirements associated with poor quality water, in-turn improving the efficiency of the operation of the equipment.

MIBC & Diesel Upgrade

The purpose of the Reagent System Upgrade project at Glencore's Oaky Creek Coal Mine was to install new reagent storage tanks, discharge / delivery pumping system and automated flow control distribution manifolds for the delivery of each reagent to the nominated process connections. In the event of failure of the automated flow control system, rotameters for manual reagent addition were included as a contingency.
